Nipple on Harbor Freight Regulator?

[njviking]

Just picked up an extra regulator from harbor freight and am having a heck of a time getting the argon nipple out so I can install the Co2 nipple.

Anybody have experience getting one changed. I'm known to destroy things by exerting too much pressure and figured I'd ask before twist it into a pretzle.

Thanks

Is it left hand thread? I know when I put two regulators together I had to get a double left hand thread nipple

Its not cut marked, but then again that doesn't mean anything.

good point. I'll go check.

I just checked my HF regulator... regular threads on mine... It was a ***** to get out though... funny because I ended up reinstalling the argon/ oxygen tank attachment and using it for a tank of beergas (nitrogen/co2 mix)

Nope, regular thread. I hit the body real quick with a torch and it spun out with a little muscle.

Seems to be working. We'll see.
