Reg question

[baywatch106]

Ok, I just got a Pressed steel 120 cu tank that I believe has the smaller 7/8 thread( pressed steel dot-e9791-3500tp5250 10-96ia571059ps81 union carbide) . The valve is a din valve. My current 1 st stage is a scubamax yoke reg. Should I get a yoke to din converter,than get a din to yoke converter---( I have another tank that is yoke)-- -- get a din 1st stage and buy a din to yoke adaptor? Any ideas on which way to go?

Is your 120 a LP tank? If the DIN valve has 200 Bar threads, you should be able to screw in an insert that will make it yoke-compatible. If not, I'd suggest either a DIN or DIN-adapted reg.

I believe it the 300 bar from reading all the posts on the pressed steel tank. ( i dont have it yet)

In that case, you probably don't want to be using yoke regs with it if you can help it, as they may not be rated to use with a high pressure cylinder. Get DIN first stages and a yoke converter (for travel, etc) and you'll be good to go. Your LDS may be able to convert your existing reg to DIN, but I don't really know the scubamax.

If its the same valve I had with my old PST 120, you'll need a din first stage.

What I'd do, convert to din reg, convert the other tank to din and buy a yoke adapter for the din reg.

All of my regs are din and all of my tanks are din. I do have 3 or 4 yoke adapters laying around as well as a couple of yoke K valves.

want to sell an adaptor?

I don't think the yoke K valve will work with those threads if it's the tank I think it is. It has different threads than most other tanks. But I agree that you should change your reg to din & get an adapter when you use another tank. Plus, if you do convert your reg, be sure your LDS gives you the yoke parts back. Then if you go on a trip where you'll use rental tanks, you can convert your reg back to yoke so you don't have to use the adapter.
