Hey, brand new to this forum and need help.
I have an old steel tank from 1958, just hydroed, tumbled, VIP'ed, and filled.
However, the o-ring is not good any longer and very hard to find as it is a strange setup.
The o-ring outside diameter is 3/4 inch, inside diameter hole 3/8 inch,
and the back of the o-ring is FLAT. Not flat from wear, designed t be flat in the back against the actual valve.
The valve is chrome plated brass (I believe 1/2 inch tapered thread),
straight square vertical about 4 inches, with on/off handle at the top (like an O2 bottle design).
Any idea where I can find replacement O-rings???
