I'm now following this thread with great interest. Yesterday I was driving my Handyman &, after an extended time of not needing to brake, stepped on the pedal & had to really push to get the old gal to stop. I was near home so I carefully drove back & looked under the front to find the right brake hose dangling. The banjo bolt had fallen out! I had used copper washers like you're supposed to & now I have to decide how to keep this from happening again. Luckily, NAPA had another bolt, but I'm thinking of getting some Stat-O-Seals from Summit. Sheesh!It's always something.

Maybe there are different types of rubbers used in them? Wayne says they work & hotrodg says not to use them. I think in theory they'd be just the ticket, but I'd like to be sure & get the right ones. Is it because the brake fluid degrades it or because they might not take the pressure? Or both?
"Real" Statoseals are made by Parker. They are available in a number of rubber compounds.
The "normal" or "generic" Parker Statoseal uses nitrile rubber. Both Earles and Russell show their Statoseals to be nitrile. They probably buy them from Parker since they are using Parker's trademarked name. Nitrile is NOT compatible with automotive brake fluid.
Parker does show a compound that is compatible with automotive brake fluid.
Without getting too much farther into it, that's what's going on here.
