What type of high pressure propane regulator would you suggest I use.
Hey @Slowhand, welcome to Blacksmith Forums!
I usually run my forge ~10-15lbs of pressure, there are quite a few propane specific regulators that go 0-20 or 0-30, just cause sometimes you might want to put it up to 15 or higher for forge welding.
It really depends on what you want to spend, I have a propane regulator with a couple gauges (tank side, hose side) and a needle valve that has a good range (0-50 I think) but that’s way more than most need. A 0-20 or 0-30 should do ya fine.
