Just had a steal 72 hydroed, it passed no problem but when I inspected the threads on the valve they were almost non-existant. Now the problem is the valve is a 1/2 inch NPS that's with the O ring not the NPT. Does any one know of a source for these valves. I don't care if it is a J valve.
 
Here is a Sportways valve that has that kind of threads:

Here is also a White Stag with the same thread:

Here is a Demone in nice shape. I think it is the same threads This is very rare.
Vtg 50's Rare Demone 1/2" J Valve Straight Thread Vtg - eBay (item 130426667309 end time Sep-07-10 02:54:06 PDT)


They are all from the same seller. IMHO, his prices seem a bit high, but it is hard to compare since they are fairly rare items. They do come up on eBay evry once in a while.


Good luck
 
Thanks for posting these up as I had not seen 1/2" straight threaded valves before.
 
I have a couple of good Sportways valves. A J and a K; both are 1/2" straight O-ring valves. PM if interested.

Thanks, not sure how to PM you but I am really interested in the J valve. The cylinder came with an identical valve as yours. If you know how to PM me please contact me with a price.
Thanks, ZDD

I know this is a really old thread but I just came into ownership of one of these 1/2 nps valves. Does anyone know the oring size for these? Thanks in advance.

oh and are these 1/2-14 like the current are 3/4-14?
