Regulator Nipple ID

Trying to figure out what adapter this is on a Victor HPT270. It's not a 320, and obviously not a 580, just trying to figure out if I should swap it out for a 320 stem entirely, or if there is an M -> 320 F adapter that would work with this one.



Anyone have a clue what this is?

Not sure what it is. An adapter, if you found one that worked, would make the inlet pretty long. I'd just remove it entirely (pipe wrench works best in my experience, ideally in conjunction with a bench vise) and replace. If you don't mind the color, a brass nipple and nut from Western Enterprises (AirGas is a WE retailer) should cost $10 or less.

That nut likely will slide down the nipple so you can get at the nipple. You may have to smack it on a hard surface or twist it down. Can't see inside, but is there a washer crammed in there?

No, it's a filter screen and a tapered surface, looks similar to a 580 with a slightly larger hole and screen in the middle.

Anyway, I'll just swap it out, I didn't even think of how long this would end up with an adapter if even one exists. Hopefully this one comes off relatively easy. Last one of these I did was ridiculously difficult to remove.

Pretty sure it is not a 320.. Just replace it..

err side says Oxygen.. Let me guess..CGA 540...

also the reg may not go much past 30 psi.. Victor usually put "double range" gauges on..So 60psi gauge means reg. tops out at 30...ish..maybe

If you have any trouble or lack tools to change it out, I might be able to help as I'm somewhat close. I pick the nipples and nuts up from a local shop to avoid waiting and paying shipping. Give me a PM is it gives you problems.

Facepalm... Pretty obvious now.

I typically only run 10 - 20 on the output so 30 should be fine. Makes the gauge usable as well.

Thanks. I'll let you know. The last one I did was in pretty used shape, so hopefully this goes smoother.

What shop do you go to locally? I couldn't find the right part at granger so I was going to order online but would be easier to get local.

Good enough. Sometimes it feels wrong to ask for this type of help so thought I might offer first?
I was downtown so went with going to a shop on Chicon but if you are in different part of town, I would do a few calls to ask if the closer guys might have them.
