Stainless steel elbow: dimensions and dimensional drawing to EN 10253-4
All dimensions of the stainless steel elbow to EN 10253-4 in one table, the dimensional drawing of your size above it – available from stock or to order. Elbows in stainless steel are covered by a part of the fittings standard of their own: EN 10253-4. It is built to the same pattern as part 2 for steel – and gives different figures throughout. This page carries those figures: pick design, angle, outside diameter and wall thickness series, and the page shows the dimensional drawing, the dimension table and the limit deviations for exactly that size. What a design 2D, 3D or 5D is, and how type A differs from type B, is explained on the elbow basics page.

Dimensional drawing for your size
The dimensional drawing – also called dimension sheet, outline drawing or dimension sketch – shows every dimension and the tolerances for your size.
How it works: Choose 3D in the field “Design”, 90° in the field “Angle”, 114.3 mm in the field “Outside diameter” and Series 2 in the field “Wall thickness series”. The dimensional drawing immediately shows every dimension of the stainless steel elbow with tolerances, the table below all sizes. “Print this size as PDF” takes the drawing with you.
Example 90°, design 3D, 114.3 × 2.6 mm: outside diameter D 114.3 mm, wall thickness T 2.6 mm, inside diameter ID 109.1 mm, bend radius (also the centre-to-end dimension F on a 90° bend) R, F 152 mm, back-of-bend to centreline distance W 209 mm, pressure factor (type A only) X 77 %, mass 1.7 kg.

Select design, angle, outside diameter and wall thickness series – the drawing and the dimension table then show exactly that size, with the figures in the drawing itself instead of only the dimension letters. What separates the designs 2D, 3D and 5D, and type A from type B is on the basics page. The dimension tables for the sizes listed here are further down this page.
EN 10253-4 covers the greyed-out sizes. Our dimension overview lists them as order dimensions – see the table “Further deliverable dimensions” below.

Tolerances (limit deviations): what range the standard permits
For each dimension the range that EN 10253-4 permits is given – minimum and maximum instead of the deviation that would first have to be worked out. In the drawing this is shortened to tolerance – the word everyone uses in practice. In technical terms the two values given are the limit dimensions of the dimension, their distance is the tolerance and the deviations from the nominal size are the limit deviations. The basis is clause 11.2 with Table 8 and Table 9, and clause 11.3 – where the standard specifies nothing, that is stated.
These dimensions have two limit deviations – which one applies depends on the specific part
For the following dimensions the standard specifies two limit deviations. Which one applies does not depend on the nominal size but on the specific part. Both cases are therefore written out.
This answer determines: out-of-roundness Ov.
out-of-roundness Ov – calculated as 100 · (Dmax − Dmin)/D, largest and smallest outside diameter in the same cross-section
Where is the out-of-roundness measured? (the standard allows more out-of-roundness on the body of the fitting than at the weld ends. The weld ends are the two straight, flat end faces at which the part is welded into the line – the body is everything in between, on a elbow the curved section, which inevitably becomes somewhat oval in bending. What is measured, in one and the same cross-section, is the largest outside diameter minus the smallest)
- at the weld ends out-of-roundness Up to D 406.4 no separate limit is specified – but Dmax and Dmin must each lie within the limit deviation of the diameter, and that limits the difference by itself.
- on the body of the fitting out-of-roundness at most 4 %
- I don't know both cases remain
What the standard specifies beyond the dimensions in the drawing
The following requirements are not tied to any dimension in the drawing. They are set out here in the structure of the standard, under its own headings. The label on each line says what kind of information it is – a dimension from the standard, a statement of the standard, an acceptance criterion on the finished part, or a manufacturing requirement.

Every dimension has its reason – whoever knows why they measure, measures better.

Where the standard gives no limit deviation of its own
- back-of-bend to centreline distance W – For the calculated dimension W, EN 10253-4 gives no limit deviation. What is limited is the centre-to-end dimension F, measured from the axis of the welding end to the centre of the bend.

Why limit deviations exist at all and how to read them is explained on a page of its own: Tolerances and limit deviations.

Without a wall thickness there is neither a scale drawing nor a complete dimension row – so these sizes are not in the dimensional drawing.
Dimensions are nominal dimensions to EN 10253-4 and do not replace the data sheet of the actual item. No statement about pressure or temperature suitability and no statement about the material. The bend radius is a nominal dimension of the standard and not a commitment about how the individual piece is made. Direct link to this size
Where it is measured – at the welding end
Measured at the welding end – D on the extended cylindrical outside surface, T as the full wall to the inside surface, as the standard enters both at the end plane – not at the root face.
EN 10253-2 and EN 10253-4 measure outside diameter D and wall thickness T at the welding ends. In the standard’s figure both are entered at the end plane: D on the extended cylindrical outside surface, T as the full wall between the extended outside surface and the inside surface – the bevel only appears to cut the wall. The root face C of 1.6 ± 0.8 mm is not T. If the end is machined (chamfered outside up to 30° and inside up to 18°, which the standard expressly allows), T runs from the edge where the outer chamfer ends to the edge where the inner chamfer ends. On the body of an elbow the wall may be thinner – only the lower limit of table 12 applies there (type A), and no upper limit is defined for the body. The diameter on the body is limited only by out-of-roundness.
Typical measuring error: Measuring with the caliper across the bevel or the inside taper gives too small a wall – a conforming fitting is then wrongly rejected.
Rule of thumb: Measure the full wall – not the root face.
How to measure correctly
An elbow is identified by three measurements: outside diameter D and wall thickness T, both taken at the welding ends and not on the bent part, and the centre-to-end dimension. The bend radius itself cannot be measured on the part – that is what the dimensions B, W and Z are for. On a 90° elbow, measure in the plane of the welding ends from the centre of curvature to the outer edge.
- outside diameter D
- measured across the edge at the welding ends, not on the bent part
- wall thickness T
- measured at the welding ends – on the fitting body it may only deviate downwards, to table 8
- back-of-bend to centreline distance W
- from the centre of curvature to the outer edge – the dimension the trade quotes
- back-of-bend to centreline distance (180°/45°) B, Z
- measure in the plane of the welding ends – from the centre of curvature to the outer edge
- centre-to-centre dimension C
- only on a 180° bend – distance between the axes of the two legs
A measured value rarely matches the table exactly. The dimensional drawing on this page shows the limit deviations of EN 10253-4 for every size.
Looking for the elbow in non-alloy or alloy steel? For that, EN 10253-2 applies – the dimensions are on the page on elbows in steel. What is written here is limited to what is different for the stainless steel elbow.
Elbow basics – designs 2D/3D/5D, angle, type A and type B as well as seamless versus welded apply to every material and are therefore on a page of their own. Here are the dimensions and tolerances for stainless steel to EN 10253-4.
Part 4 is not Part 2 with a different material
Both parts of EN 10253 are structured alike: the same designs, the same angles, the same system of pressure factor and wall thickness. Whoever concludes from this that the figures are the same is mistaken. When this page was built, the pressure factors of both parts of the standard were held against each other cell by cell: in none of the 147 comparable combinations do they agree.
Three differences stand out in daily work:
- No catalogue dimension W for the 90° elbow. There, Part 4 dimensions the overall dimension F from the pipe axis – see below.
- No wall thickness series in the main body. Part 2 carries a table of its own; Part 4 names preferred values only in the annexes and therefore only for some of the diameters.
- A second, metric dimension table with the designs D+100, 3DM and 5DM, which do not exist in Part 2.
Type A and type B: the pressure factor
As in Part 2, the standard distinguishes two versions – the system is the same for both materials and is explained in the basics. Here are the figures of Part 4. The pressure factor X is the ratio of the pressure resistance of the fitting to that of a straight pipe of the same dimensions, given in per cent.
Type A – reduced pressure factor
The wall thickness corresponds to that of the connecting pipe. Because the intrados is compressed and the extrados stretched in bending, the fitting does not reach the full strength of the straight pipe – for this the standard gives a pressure factor per design and wall thickness series. The dimensional drawing above names it for the selected size.
Type B – full pressure resistance (standard: “for use at full service pressure”)
The elbow is manufactured so that it reaches the strength of the straight pipe; for that, the wall at the intrados is thicker than at the welding end. This wall thickness at the intrados is shown separately by the dimensional drawing. At the welding end the dimension is the same in both versions – there the elbow fits the pipe, and only that counts for the weld.
The pressure factor applies to type A only; for type B it is by definition 100 %. The values on this page have been recalculated from the equations of Annex B of the standard.
Designs 2D, 3D and 5D: the bend radius
What the designs mean in principle – schematics to a common scale and the selection criteria – is explained in the basics on the designs. Here are the particularities of Part 4.
The design says how tightly the elbow is curved. The bend radius R is a multiple of the pipe outside diameter: for 3D, three times. The tighter the radius, the less space the elbow needs – and the greater the flow resistance.
A special case one has to know: in Part 4, design 2D carries no 45° elbow. There, the dimension table names only the column for the 180° elbow. The dimensional drawing therefore does not offer the combination at all, instead of offering it and then staying empty.
The metric designs D+100, 3DM and 5DM
Besides the ISO table with 2D, 3D and 5D, EN 10253-4 carries a second dimension table with the metric designs D+100, 3DM and 5DM. Bend radius and overall length are given there as ranges: they are to be agreed between purchaser and manufacturer and are not fixed catalogue dimensions. Moreover, the standard carries these designs only as type A and names no pressure factor for them.
The dimensional drawing above therefore does not show them – we would otherwise have to display a number that does not appear in the standard in that form, such as the middle of a range. They are mentioned here so that the overview leaves no gap the reader would never learn about.
The overall dimensions: F, W, B and Z
This is where Part 4 departs most clearly from trade custom, and that is why it is explained in detail on this page.
For the 90° elbow the standard carries the column “R, F” – one value with two names. F is the centre-to-end dimension, measured from the centre of a welding end to the centre of the bend; for the 90° elbow that is geometrically the same value as the bend radius R. The drawing therefore dimensions the radius R – and for the 90° elbow that is at the same time F. The dimension table therefore lists the row under both letters: “bend radius (also the centre-to-end dimension F on the 90° elbow)”.
The dimension W customary in the trade – from the back of the elbow to the centre – is not carried by Part 4 for the 90° elbow. It follows as W = R + D/2. The dimension table names it additionally and marks it expressly as calculated, so that nobody takes it for a standard value.
For the 180° and the 45° elbow the standard carries a common column “B–Z”: B is the overall dimension of the 180° elbow, Z that of the 45° elbow. The dimension C – centre to centre – exists only on the 180° elbow; there it is twice the bend radius.
In 125 sizes the standard value deviates by one unit in the last digit from the calculation R + D/2. We show the standard value and name the deviation in the note – nothing is adjusted. At ⌀ 82.5 mm in design 5D the standard value is inconsistent in itself; that too is stated as a footnote at the row and not as a silent correction.
Limit deviations, out-of-roundness and wall thickness
The limit deviations are given in the dimensional drawing at every single dimension – shown and hidden via the switch “Show tolerances”. Two rules of Part 4 deserve a mention of their own, because they do not follow from the nominal size alone.
Out-of-roundness
Up to and including ⌀ 406.4 mm the out-of-roundness at the welding ends is already included in the limit deviation of the outside diameter – there is no separate figure there, and that is not an omission but the statement of the standard. Above that it depends on the ratio D/T, that is outside diameter to wall thickness: up to D/T ≤ 100, 2 % applies, above that the out-of-roundness is to be agreed. In the elbow body 4 % applies.
So the question “where is it measured?” alone is not enough – one also needs the wall thickness. The dimensional drawing calculates D/T for the selected size itself and shows the case that applies.
Wall thickness
Upwards, the wall thickness is limited to +20 %. Above ⌀ 610 mm the standard distinguishes downwards between seamless and welded fittings – the same size then has a different lower limit deviation depending on the manufacturing route.
Which sizes this page shows – and which it does not
Dimension table A.1 of the standard carries 50 outside diameters from 13.5 to 1219 mm. This page shows dimensional drawings and dimension tables for 26 of them. The reason lies in the standard itself: Part 4 carries – unlike Part 2 – no wall thickness series table in the main body. Preferred values for the wall thickness are given only in the annexes, and they cover 26 diameters.
For the other 24 – 25, 31.8, 38, 51, 57, 63.5, 70, 82.5, 101.6, 108, 127, 133, 152.4, 159, 177.8, 193.7, 244.5, 559, 660, 762, 864, 1067, 1118 and 1168 mm – the standard names no series and hence no wall thickness value. A drawing of these sizes could only be drawn with an invented wall thickness. We do not do that.
They are not omitted for that reason, though: what the standard gives for them – bend radius and overall dimensions – is listed in the section Sizes without a wall thickness series below the dimension tables. So this group too is represented here, and where a value is missing, it says that it is missing.
Frequently asked questions about the stainless steel elbow
How does EN 10253-4 differ from Part 2?
Part 4 applies to fittings in stainless steel, Part 2 to non-alloy and alloy steel. The two parts share the structure but carry numerical values of their own: in no comparable combination do the pressure factors agree. Part 4 is therefore not Part 2 with a different material.
Why is there no catalogue dimension W in the standard for 90° elbows to Part 4?
Part 4 dimensions the overall dimension of the 90° elbow as F, measured from the pipe axis – that is geometrically the bend radius R. The dimension W customary in the trade, from the back of the elbow to the centre, is not carried by the standard for the 90° elbow. It can be calculated as W = R + D/2 and is expressly marked on this page as calculated.
What are the metric designs D+100, 3DM and 5DM?
A second dimension table of EN 10253-4 besides the ISO table with 2D, 3D and 5D. Bend radius and overall length are given there as ranges and are to be agreed between purchaser and manufacturer; there are no fixed catalogue dimensions for them. The standard carries these designs only as type A.
How is out-of-roundness limited in EN 10253-4?
Up to and including an outside diameter of 406.4 mm the out-of-roundness at the welding ends is included in the limit deviation of the outside diameter. Above that it depends on the ratio of outside diameter to wall thickness: up to D/T 100, 2 per cent applies, above that it is to be agreed. In the elbow body 4 per cent applies.
Are the weights on this page standard values?
No. The standard carries no weights. The values given are guide values, calculated from nominal dimension and wall thickness with a density of 8.0 kg/dm³. The text of the standard governs.

standard dimension: D, T, R, F, B, Z, C · calculated: W, kg · calculated: ID, X, Tint · assignment: DN
DN: EN 10253-2 does not assign a nominal size to every size. Where the dash stands there is none – the size is ordered by its outside diameter.
Dimensions outside the preferred series
EN 10253-4 pairs diameter and wall thickness through a series number. The sizes below we carry with a wall thickness that is in no series for that size – or with two wall thicknesses that are each in the standard, but not in the same series. The dimensions are established in the same way as in the grid above. Where the standard gives its values through the series number, the cell stays empty.

Where a dash stands, EN 10253-4 gives the value through the series number – and this row has no series number. This affects the guide mass from the catalogue table and, on the pipe end closures, the pressure factor and the type B wall thickness from the annexes. Nothing is calculated in their place.
Sizes without a wall thickness series – 9 further outside diameters
EN 10253-4 gives these outside diameters in the dimension table but names no wall thickness series for them – preferred values are given only in the annexes and cover the remaining diameters. What the standard does give here is the bend radius and the centre-to-end dimensions, and that is what stands below.
No wall thickness, no mass, no pressure factor – all of them hang on the wall thickness, and an invented figure has no place here. For the same reason there is no dimensional drawing for these sizes.

Order dimensions and values calculated by us; deliverable from stock or to order, availability on request. Limit deviations and figures from the standard: see the main table and the standard itself.
The dimensions given are nominal dimensions. The masses are guide values calculated from the nominal dimension and the wall thickness – the standard gives no masses. The text of the standard prevails. The German edition DIN EN 10253-4:2025-10 reproduces the European version EN 10253-4:2025.

Where do I find the dimensions of a stainless steel elbow 90 degrees DN 50 to EN 10253-4?
The dimension table on this page lists all available sizes to EN 10253-4; the dimensional drawing above it shows the selected size with all dimensions and tolerances and can be printed as a PDF - the data sheet for your size.
Where is the wall thickness of a fitting measured – and does it apply in the bend?
At the welding end, as the full wall the way the standard enters T at the end plane – not at the root face and not across an inside taper (EN 10253-2 and -4, clauses 11.2.1 and 11.2.3). In the bend the wall may be thinner, but for type A fittings it must not fall below the lower limit for the welding ends. There is no upper limit on the body.
