PTFE Gasket Tri-Clamp DN 40

Works well with all our DN40 (ID 38 mm) fittings.

PTFE gaskets are great when you need to rotate an installed fitting. Often you will need to tighten them a bit more than a silicone gasket to get a good seal.

• Inner diameter 38 mm
• Outer diameter 50.5 mm
• For Tri-Clamp size: 50.5 mm = 1.5"
• Temperature range -70C to 230C

These DN40 gaskets are have an appromimately 3 mm wider inner diameter than standard 1.5" gaskets.
