Regulator keeps freezing up


Recommended Posts

So I run my forge at about 15 psi on a 20lb tank, no problem. I got a 40lb tank and the regulator looks like Antartica! My step-dad said the tank was set up for liquid and I should just turn it upside down. Thoughts?

What Justin said. If you try to run liquid propane through a gas regulator you will destroy it. And possibly you and your shop as well. A 40 lb tank for forge use looks just like a grill tank only taller.

It's not a fork lift tank, it's identical to the gas grill one just doubled in size. I run propane forklifts at work and know the difference. That's why I'm confused on why it's freezing up. The previous owner, my bil, used it with those Lil space heaters you mount on them to heat the garage

Hmmmm... well, I'm at a loss now too! I run a two-burner heater with a 40lb tank with no issues, and I once used it on a turkey fryer and it didn't freeze the regulator.

There is no tube, don't turn it upside down! If it doesn't have an OPD valve it may be overfilled so you're pulling liquid. Try cracking the valve with nothing attached and see what comes out. Point it in a safe direction and wear gloves just in case, you don't want freezerburned hands or face.

it might be overfilled, when i first got it filled, the little hole behind the port was hissing and faint gas smell then i ran it and it went away. I'll crack it this weekend and let some of it out to see. The guy that filled it was old school and didnt even have it on a scale so id say its too full
