Product Questions & Answers

Got a C-604 coupler that's been leaking a good while now, this the right seal kit to fix it up?

Question by: Todd C on Oct 5, 2025, 12:06 PM

For the C-604 coupler, this is the correct repair kit. It carries the part number C604K and is built specifically for that coupler. The kit uses a black O-ring seal, so if yours has worn down or started weeping fluid, swapping in the new seals from this kit should get it back to holding pressure like it should.

Will this seal kit fit my C-604 coupler, or is there more than one version? Just want to be sure before I order.

This kit is specifically for the older style C-604 coupler that uses a black O-ring seal. If your coupler has that black O-ring, this should be the correct kit.
