Re: Water quick-disconnects for tender/loco

failure is from dropping the o-ring on the ground and not having a spare. properly done, o-rings work just fine...but ALWAYS have a few spares on hand. Even the o-rings in Joe Tansky's fittings (Joe doesn't make them)...occasionally 'get cut' and leak air and can cause problems as a result. I always...

Re: 3/4" Scale J1e
