Re: torch check valve in reply to tractordanp, 02-19-2012 15:59:51 HI Guy's put the check valve at the torch end of the hose. Or you could end up like me. With 80% of my back burned 3 Spots were 3 deg. burnes. Had to wear a special vets for about 2 Yrars NOT FUN. The check valves were at the reg. Missed 30days of work. It took some time befor i would use the torch and when poped back when sone one eles was useing it i would about pump out of boots. THINK ABOUT IT EVERY TIME I USE A TORCH!!!! BE CAREFULL Thank You Rod in MN

Puddles, the flow is backwards because the long ones go on the regulators, this is the type we use. buy em at Praxair and says right on the package for regulator use only.

You're correct torch safety, I didn't notice the black mark!
I can almost get the short regulator style on the acetylene gauge inside the propane valve protection. If I replace the long crimp ferrule on the hose with a short one I'm sure it will work. But I'll wait until my new "T" grade hose gets here to see what size ferrules it has on it.

First, flashback arrestors are not the same as reverse flow check valves. That's why they have a different name. LoL F/A's are better(they will stop a fire going back and are also reverse flow check valves). As far as where they go, they will only go in one place because of the type of threads they have. Torch would have B fittings and regulator should be NPT (1/4" I think). Additionally it should tell you in the manual that comes with the torch set. You can get F/A's for the regulator, the torch and hose to hose depending on what you want or need.

Disregard the different threads line above. I was thinking of quick couplers that thread directly into the regulator. The arrows and/or blowing through F/A's will tell you where to install them. I had a customer that wanted quick couplers at the reg. side so he could take his hoses off and connect them together...Acetylene to Oxygen!!!! That's why they make quick couplers a different size. Otherwise you could use couplers for an air hose.

NEVER connect the fuel and oxygen hoses together, NEVER!

They should also have an arrow on them indicating which way the flow goes.

Well, if I would have opened the package I could have read which ones are which! If by chance you can not read the package, the small flashbacks go on the regulator, and the large ones go on the torch.

But as most things with welding equipment, not as easy as you would think! The flow is backwards! :roll:

Puddles, if you look on your blue package, the regulator box has a black mark to indicate they're for the regulator.

Some places such as Cargill, ADM, and others I do millwright work for require regulator mounted arrestors. The torch mounted ones are not allowed. Their safety people insist torch mounted arresters do not meet the current OSHA regs for our work.

One guy actually explained the reasoning to me that if something hot melts a hole in the hoses the torch mounted arrestors will do nothing to protect the tanks. Made sense to me

Buy a new set of Victor brand, and the valves are built into the regulators.

I have a set of Flashback arrestors with plus check valve made by Smith H7 10. They are for the regulators. The way they are made it is impossible to put them on backwards. At work we used back flow preventers at the torch handle, not sure what brand, maybe Harris. Those were impossible to put on backwards also. Unless you did some creative plumbing. Maybe different manufactures make them a little different. All the ones I have seen can only be put on one way. Just like you can't put an oxygen hose on an acetylene regulator. Things are made like that so people can't make an honest mistake. This is just from by experience.

They make them that will attach either place and either will work just as good as the other. The ones attached to the regulartor will be female inlet and male outlet, and the ones to the torch will be male inlet and female outlet. Like others have implied they can't be used in place of each other because that would involve reversing them and if reversed no gas will flow through them.

If I remember correctly, there are two types, one that attaches to the regulators, then the hoses attach to the flash backs. The other type attaches to the torch, and the hoses attach to the flash backs.
I have several sets of flash backs still in boxes, but I don't know where they attach to. Does anybody have a number for which ones are which? I have flash backs on my regulators now, but I'm switching over to propane, had to go with a small gas regulator to fit inside the valve protection of the propane tank, it's so tight inside there a flash back won't fit on the regulator. So now I'd like to have a flash back on the torch, but don't know which ones to use. Any help?

Flash backs are just a check valve. They will not let any gas/fire/oxygen back into the tank or hose. So just see which way is checked and which way is free flowing. I bought a set of regulators and torch off a pawn shop a few years ago. The guy sold them to me real cheap as he thought that they where bad. They just had two sets of flash backs on them. They where on backwards. So there was not any flow either way in the hoses. I took all of the flash backs off and the torch worked fine.

Mine came attached to the torch when it was new. I "think" you can test them by reversing them, without the torch attached, and holding them in a bucket of water. Should be no bubbles.

The flash back protectors go on the regulator then the hoses hook to them.
