# Copper tube Types K, L, M and DWV (ASTM B88 / B306): OD, wall and ID, 1/4 to 12 in, + 100 mm hollow sections

> What are the OD, wall thickness and ID of Type K, Type L, Type M and DWV copper tube, including 2-1/2 to 6 in?

- Category: Tri-clamp & pipe › Pipe, tube & threads
- Kind: Standard part
- Basis: Engineers Edge's ASTM B88 / DWV table (all four types), Engineering ToolBox's Type K table and Zoro's K / L / M ID table agree where they overlap; a copper-tube weight sheet is a fourth, independent check on the walls

**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Copper water tube is sold by nominal size, which is not a measured dimension: the actual outside diameter is the nominal size + 1/8 in at every size in the tables (1/2 in is 0.625 in, 2-1/2 in is 2.625 in, 6 in is 6.125 in). The type letter only changes the wall: Type K is the thickest, Type L is the medium wall, Type M is thinner, and DWV (drain, waste, vent) is the thinnest of all (Zoro: very thin wall, for drain-waste-vent use only). Type K and L are made in 1/4 to 12 in, Type M from 3/8 to 12 in, DWV from 1-1/4 to 8 in in the tables read.
- ASTM B88 covers seamless water tube (K, L, M); ASTM B306 covers DWV tube. The standards themselves were not read. The numbers are Engineers Edge's table (inch, OD, ID, wall for all four types); Engineering ToolBox prints the same Type K table (18 sizes, OD, wall and ID equal), and Zoro prints the same K / L / M IDs for 1/4 to 3 in (every value equal). In every row of the Engineers Edge table the ID equals OD − 2 × wall to within 0.001 in (checked in this script) except one: its DWV 3 in row prints an ID of 3.030 in, where 3.125 − 2 × 0.045 is 3.035 in; the wall 0.045 agrees with the weight sheet, so the ID shown for that row is the derived 3.035. Millimetres are inches × 25.4, rounded to 0.01.
- Weight per foot is from a copper-tube weight sheet (title 'Copper Tube for Plumbing and Mechanical Applications', 2022-04-06; the maker is not named in the text read; the column is headed WT/FT and no unit is printed, read here as pounds per foot). It is not a second source for the walls, but it is consistent with them: weight ÷ ((OD − wall) × wall) is constant to within 0.8 % across every size of each type (a check made here, not a published statement).
- 1/4 to 2 in Type L and M are on copper-pipe-type-l-m; the Type L / M rows here repeat them so one table covers every size. Plumbers call this 'copper pipe' and 'copper tube'; the tables here are the water-tube sizes (nominal + 1/8 in OD).
- Files: 100 mm hollow sections of Type K (all 18 sizes), Type L and M from 2-1/2 to 6 in, and DWV (all 8 sizes). They are plain annuli at the published OD and wall; the length is Xem's example length. Sweat (solder) fittings grip this OD: see copper-solder-fittings-b16-22-sizes. EN 1057 metric tube (15 mm, 22 mm, 28 mm) is a different size system: copper-tube-metric-en-1057.

## Questions

**What is the OD and wall of 2-1/2 inch copper tube?**

Actual OD 2.625 in (66.68 mm) for every type. Wall: Type K 0.095 in, Type L 0.080 in, Type M 0.065 in.

**What is the ID of 3 inch DWV copper tube?**

OD 3.125 in, wall 0.045 in, ID 3.035 in (77.09 mm) (OD − 2 × wall; the Engineers Edge table prints 3.030).

**Why is 3/4 inch copper pipe 7/8 inch OD?**

Copper tube is named by nominal size and its actual OD is the nominal size + 1/8 in at every size in the tables: 3/4 in is 0.875 in (22.225 mm).

**What is the difference between Type K, L and M?**

Only the wall: at 1 in Type K is 0.065 in, Type L 0.050 in, Type M 0.035 in (same 1.125 in OD).
