I can't find how to post a new subject, but I have a problem with the Vans gascolator O ring.
I had a leaking O ring and tried to get a replacement locally. That was no good so I got one in from Vans. That one leaks. The gascolator is a Vans G4
Has anyone else had O ring problems with this Usher manufactured gascolator? Does anyone know the actual sizing of the O ring?
I can't understand why the O ring should suddenly leak and a new one not work. There is nothing visible and a pressure test proves it is the O ring, not a leaking thread or gascolator body.
