Notes

  • End cap: ISO 2852 face (rim 2.85, recess 1.6 inside the groove diameter, 20° back) on a 6 mm solid disc. Drill feedthrough bosses at least 6 mm in from the rim so the clamp still seats.
  • Gasket (ISO 2852 Type B, all sizes): bead thickness U 5.5 mm sitting in both recesses, web T1 1.7 mm between the sealing lands, compressed thickness V 2.1 mm, inner lip 1.1 mm thick × 2.8 mm long into the bore. Outside diameter ≈ groove diameter (56.5 mm for 2 in).
  • Silicone to ~230 °C; EPDM, Viton and PTFE for other service. For an engine, a PTFE-envelope or silicone gasket on the hot end.

Questions

What are 1.5 inch and 2 inch tri clamp gasket dimensions?

1.5 in: 50.5 mm OD, 35.8 mm lip ID. 2 in: 64.0 mm OD, 48.8 mm lip ID. Both: bead 5.5 mm thick, web 1.7 mm, compressed 2.1 mm (ISO 2852 Type B).

Which gasket material for a hot tri clamp end?

Silicone to about 230 °C, EPDM and Viton for chemicals, PTFE or PTFE-envelope for the hottest service.

Where can I put a feedthrough in a tri clamp end cap?

Drill or model bosses at least 6 mm in from the rim so the gasket land stays flat; the free STEP cap here is a 6 mm disc with the ISO 2852 face.
