So I'm currently rebuilding a cocker that's been sitting in a closet for years. I noticed that the LPR was not working correctly so I took it apart and found this on the tube...
The dry rot ate away at the o-ring and some metal plating has been chipped off. I can still see some slight "bubbling" around the damage. After a vigorous wipe-down, I can't get any more shards or flakes to come off my finger when scratched.
Do you think I need to replace this tube? What kind of lube should I be using on the new o-ring?
Thanks in advance.
