Notes

  • Schedule 40 and Schedule 80 PVC share the outside diameter (the steel NPS OD); only the wall differs, so both fit the same sockets and fittings. Sch 80 is thicker inward: 1/2 in has a 0.109 in wall in Sch 40 and 0.147 in in Sch 80.
  • Sources: OD, minimum wall and ID from Westlake Pipe's Sch 40 / Sch 80 table; OD and minimum wall repeated by JM Eagle's spec sheet (Rev 12) for all nine sizes (equal); Sch 80 minimum wall and ID repeated by McMaster-Carr's Schedule 80 pipe page. In every row Westlake's ID equals OD minus twice the minimum wall (to 0.0015 in). The Sch 40 sizes 1/2 to 2 in match the existing 'schedule-40-pipe' page (OD 21.34 to 60.33 mm, walls 2.77 to 3.91 mm).
  • Minimum wall, not nominal: real pipe is thicker and OD has a tolerance. The ID is a calculated value, not a control dimension.
  • STEP/STL for Sch 40 pipe stubs (1/2 to 2 in) are on 'schedule-40-pipe'; no pipe files are repeated here. Left out: Sch 40 / 80 OD tolerances and sizes under 1/2 in and over 4 in (in the same tables, not asked), Schedule 120, and pressure ratings (differ by maker and temperature).

What is the difference between Sch 40 and Sch 80 PVC?

Wall thickness only: the OD is identical, so the same socket fittings fit. 1/2 in is 0.109 in thick in Sch 40 and 0.147 in in Sch 80.
