Looking for 2 yoke valves with 5/8 or 11/16 threads, Can Anyone Help Me Out?!

[ra516]

i need to change the valves on my tanks to yoke, but they dont make them any longer in the thread size that I need from what I have heard. I am looking for someone who has 2 yoke valves they are willing to part with that are either 5/8 threads or 11/16 threads. Any help will help me out a lot.

Thanks,
Reilly

I think you need to do a little more research into what the threads actually are, as I have never seen or heard of 5/8" or 11/16" scuba threads.

What tanks are they? 3500 PSI steel? If so those are 7/8" UNF threads, and there have never been yoke valves made in that thread.

If you knew a machinist, you could get a standard set of valves turned down and re threaded to fit.

Are your perhaps trying to adapt a non-scuba tank to scuba? If so it is a thankless and rarely rewarding job.

First thing to do is positively identify the threads.

Welcome to the board. Once you have 5 post, put some photos of the tank necks, model numbers and of the valves you have. Then we may can help you.
