# Sanitary clamp end caps, 10 and 12 in (16AMP, tri-clamp style)

> How thick is a 10 inch tri-clamp end cap?

- Category: Hardware › Sanitary clamp fittings
- Kind: Standard part
- Basis: Steel & O'Brien 16AMP: A 0.480 in, B 10.570 / 12.570 in; ISO 2852 face profile

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

## Notes

- Drawn at 0.480 in (12.19 mm), the Steel & O'Brien value; other makers list 0.500 in (Shaw) and 0.562 / 0.625 in (Holland), so measure the cap in hand. The flange diameter agrees across all three.
- At 6 bar gauge a 0.480 in cap simply supported at the gasket groove sees about 85 MPa at the centre and bows 0.35 mm (Roark, uniform pressure): a large cap carries a large load (10 in: 32.1 kN at 6 bar). The cap must be rated for that at its temperature.
- The gasket-groove diameter (C2) at 10 and 12 in is not in ISO 2852 (its table stops below these sizes): it is drawn at flange − 7.5 mm, the land width the site already uses for the 4 in, and stated as derived. Everything else here is from the cited tables.
