Are there Yoke or Convertible (DIN/YOKE) valves available for the 7/8" PST tanks?

Are there Yoke or Convertible (DIN/YOKE) valves available for the 7/8" Pst tanks?

Buy two din filler things and screw one in.

Hack excess threads off to flush with filler.

Polish with file to smooth.

Swap fillers

Have someone else do it?

No, there are not. That said it has been reported that more than one person has taken a std 3/4" NPS and re-threaded to be 7/8" UNF. But unless you can do it yourself or have a friend with a shop that will do it do a 6-pak of beer your best route is to either convert your regs to DIN or sell the cylinders and get the modern HP equivalent.

Well I just ran across some pictures of 4 Pst 120s that I bought some months ago, & sold them right away....

here is a pic of the valve...

just wondering where they came from

sounds like the PST tanks you bought/sold were the modern std 3/4" NPS version, so that's why they're already equipped with the 'convertable' (screw in adapter) tank valves.

Sorry, posted this in the wrong place.

Those cylinders are 3442 psi cylinders which use 3/4" NPS DIN/Yoke valves, the older PST are 3500 psi which are 7/8" valves and DIN only.
