i spent 11$ on a can of MPS gas and when i hooked it up to my gun it would clog the adapter up and i cant get pressure into my meter

did i get a shitty can of MPS or does MPS suck

i thought that mps was really good. i have never done a mps gass metering but i have a torch that runs off of mps and it does not get cloged up. check to see if you have something else is the adapter or hose. cause mps should not clog up anything

What's MPS gas?

mps gas (also known as mapp gas) is about the same as propane but it burns hotter. somewhere i saw excactly what it is made of but i cant remember it that was on this site or not. anyways it is just like propane

What is the temp? And when you fill it is the tank valve pointing up or down?

Oh, I know what MAPP is...

Oh, I know what MAPP is, I'm just not used to people referring to it as MPS...

I had this exact problem with MAPP and my Taternator II. After a shot or two, the gas would stop flowing. At first I thought it was my regulator getting iced up inside, but then I noticed that after unscrewing the tank, gas would fisss out of the stem of the torch head, but there was no pressure at the inlet side of the regulator.

After much trial, error and cursing, it turned out that the MAPP was freezing the check valve inside the torch head's stem - the short bit that actually pokes into the tank and opens the tank's little ball bearing valve. To fix, I unscrewed the stem from the torch head, then drilled out the spring and tiny check valve inside it. The stem was very hard to remove because the threads are locktited. Be careful not to scar the shiny stem surface. I reassembled the stem with a fresh coat of locktite on the threads. Works like a charm! I suspect that this check valve freezes by design, preventing liquid fuel from entering the torch head.

A propane torch head can't be used with MAPP/MPS/Razor gas, but you can use a MAPP/MPS head with propane. So its the propane rig not the tank.
