    Hi Hank, The regulator doesn't seem to regulate, it is about 30psi out. Turning the knob on the front makes it open or close/stop the flow of Hydrogen.  Maybe it never adjusted, it just seemed right pressure and i accepted[…]

    No need to spend more than about $100. Some regulators have to be built using special materials (like those for corrosive gases), but hydrogen and oxygen regulators are built the same and I have purchased 4 or 5 oxygen regulators[…]

    Carlton,That's exactly the model Larry is looking at!  It's listed by Smith as a single stage by the way with a 3 year limited warranty.  Not likely you could find a two stage regulator, new, through a distributor, for that[…]

    On this list right hand to left hand adapters have been discussed and bought by several groups.  There were even part numbers specified, IIRC.  That way their tried-and-true helium regulators didn't go to waste when a lot of the groups[…]

    I'm no expert on regulators so I'm hesitant to give an opinion.  If you can find reputable reviews for this brand, it should be just fine.  Mine is a well known brand thst I bought on ebay that wasn't too[…]
