Ok, so I disconnected my backhoe hydraulic lines and they had built up pressure. Had to hit the male fitting to relive it and somehow rolled the poppet O-ring off.
When I pulled the fitting, the internal
c-clip was a wire. That clip holds the pressure spring and poppet in place.
But may have also been inverted. Meaning the shape had the dome UP (as you look into it).
I bought a replacement from my dealer and it was NOT a TYM brand fitting. It has a proper c-clip and the mechanics has the dome facing down.
My questions:
1) Why would TYM use a wire and make the part less serviceable?
2) If the dome cage is directional (and directly affects the pressure relief spring) would the pressure be different between one hose and the other? (The other fitting seems to be constructed similar to the replacement part, with cage dome down and a proper c-clip).
This image is the problem child. The wire “c-clip” is missing, in my attempt to remove it, the clip shot off in some random universe to be lost forever. But you can see the cage and its pressing upward. The scratches are from small pliers trying to grab the ears of the wire clip but they were aligned with the legs of the cage with no room or material to grab.
This image below is the other fitting, same wire c-clip, but the cage is inset, or facing down.
Here is a replacement fitting with a c-clip also cage is facing inward (or down).
