got a 3/4 camlock setup, is this the right gasket material for moving liquids?
Answer by: Customer Support on Oct 24, 2025, 6:05 PM
For liquid service, Buna-N is a common seal choice and that is what this 3/4 inch cam and groove gasket uses. It is specifically called out as designed for use with liquids.

It's made to fit a 3/4 inch cam and groove fitting.
Question by: Brent E on Jun 23, 2025, 11:10 AM
Got a 3/4 inch cam lock setup on a liquid transfer line and the gasket's shot. This a straight swap for the existing seal, or do I need to worry about it fitting different brands of couplers?
Answer by: Customer Support on Jun 25, 2025, 8:27 AM
As long as your couplers were built to standard A-A-59326 or DIN 2828, this gasket will interchange without any fitment headaches. That covers the vast majority of cam and groove hardware out there. Worth knowing that 1/2 inch and 8 inch sizes don't follow those standards and tend not to cross between brands, but the 3/4 inch falls right in the range where interchangeability holds up. Buna-N is a solid general-purpose seal material for liquid service, so if that's what your line is running, you're in good shape.
