Use Nylon....PSS uses them in their shaft seals....no real force, no real pressure and if worried about breaking put a cover on it.


SS and bronze lasts a pretty long time unless something else is wrong. Heck we put bronze props on stainless shafts...yes different alloys have different characteristics but holy cow...not that much different.


Even brass in bronze, isolated from most everything else by a mile will last a long time, ask all of us that have found them on our 30 year old trawlers.


Sure there are better materials, but lets not panic yet...check them regularly (not even daily or weekly...but regularly) and when you can break it off in you hand with a sharp blow, it's time....hopefully you have the replacement in your hand.


If your boat can sink from just that fitting, you may want to rethink your bilge pump system.
