Product Questions & Answers

got an older C-604 coupler that's starting to weep hydraulic fluid around the seal, is this the right kit to fix that, or is there a different one I need?

For the C-604 coupler, you want to confirm you're picking up the newer style kit, which is what this one is. It carries the blue or green polyurethane lip seal, so if your existing coupler has that same seal style, this kit is the correct replacement. The part number to cross-reference is C604K1, and it also goes by catalog number C1FZ31 if you're working off a parts list.
