Hey, Ron - I'm just finishing up the rebuild on a Sportsways SJ2 - Twin Manifold. I need a couple tank valve o rings in 90D. My valves are 3/4 inch straight threads.

Having trouble finding some in 90D without buying 20 of them. My really ancient tanks don't have the square profile recess cut - just the inwardly tapered cut in the neck.

Thanks

George, I ran out of those probably about 3 years ago, but McMaster-Carr has them really cheap.

Thanks, I was able to go into the back room of my LDS on Wednesday and I found 4 of them - cleaned them out

Do you know the size designation on those? I have just been picking some that fit from my metric box, and while not having any problems, would prefer to use the correct size.

Just realized it may be a "Boss" type oring, #912. Can anyone confirm that?
