ASTM D2241 PVC pressure pipe chart — outer diameter and wall thickness
PVC pressure pipe (CTS-adjacent iron pipe sizes). Walls are minimums, so a derived bore is a maximum. This table covers 9 nominal sizes from PVC 1/2 to PVC 8. It gives the outside of the pipe and every wall we publish for it; the bore each wall leaves is on that size's own page.

How to read this table
- OD is fixed per size. Changing the wall changes the bore, never the outside. A Sch 40 and a Sch 80 of the same nominal size fit the same fitting, clamp and hole.
- Wall series here:Sch 40, Sch 80— a “—” cell means that combination is not published here, not that it does not exist.
- Walls here are minimums. A pipe may be thicker than the number in this table, never thinner — so a bore computed from it is amaximum. The size pages label it that way.
- Millimetre columns are derived from the inch value × 25.4 — the standard is inch-native, so the inch column is the one to quote.
Size pages
Each size has its own page with the wall series side by side, bore in both units, DN and sources:
PVC 1/2 · PVC 3/4 · PVC 1 · PVC 1 1/2 · PVC 2 · PVC 3 · PVC 4 · PVC 6 · PVC 8
Same nominal, other materials
ASME B36.10M (welded and seamless steel pipe) · ASTM F876/F877 (CTS) (PEX tubing) · ASME B36.19M (stainless steel pipe)
Edition not captured. The numbers are confirmed by two independent published sources, but we have not verified which printing of ASTM D2241 they came from, so no year is claimed here.How values are verified and what is still open.
