    Never said they were dowty washers. Just an alternative that is much like the OEM washer.

    Actually they're metal topped with a rubber sealing surface. They're also concave shaped like a spring washer so they don't release pressure as the rubber contracts. Have had them in my bikes for years. No deterioration over that time and no leaks. Mount them with the rubber surface facing the tank and the metal towards the bolt. 1/4 inch works great.

    Darn, with so many daily riders it's hard to decide which one to jump on next.;)

      As far as I can tell the OEM washers look line the ones JTGS850G posted.At least the ones I've gotten off various bikes have been.I'm going with bwringer's nylon washer idea backed up by a bit of RTV on the bolt just to be sure.We did go to the dealer yesterday.I got a shock when the parts girl told me that it was $8 for the "O" ring.Could have dropped me with a feather,sure you can get them for $4.50 in the US but shipping and the weak CAD will make it mute.Note to self check the dealership here,it might not be as bad as I think!

          When I can't get Dowty washers, I smear under the bolt head, both sides of a steel washer, and the mating surface of the petcock with Hylomar. Let it set for two minutes and assemble. They never leak.

            That sounds like a plan,don't remember seeing it here but I'll be looking for it now.Did get the nylon washers but I like the idea of something more.
