Oxygen/Acetylene Welding, Check Valve Set, Torch end, use w/flashback arrestor

Description

High quality Oxygen and Acetylene Check Valve Set.  9/16 -18 threads, B Size. Can also be used with Oxygen and Propane.
These are not flashback arrestors and should not be used as a standalone defense against flashbacks. They are check valves that should be used in combination with flashback arrestors. They are only part of a flashback prevention system. Check valves are a first line of defense against flashbacks. Installed at the torch, they are meant to protect your hoses and provide some protection against flashbacks. Flashback arrestors must also be installed at the regulators in combination with these check valves.
We also carry flashback arrestors for the regulator ends.  Please click

N
ever connect a torch to acetylene and oxygen tanks without installing a set of flashback arrestors in the hoses at the regulators and a check valve set at the torch handle. Without these safety devices, it is possible a flash can occur within the hose, and ultimately follow back into the tanks, causing an explosion. This would be an extremely rare occurrence, but check valves & flashback arrestors will make it a "never" occurrence. Check valves are only a first line of defense and may not ultimately stop a flash back. Only the flashback arrestors will.
Made in China. Very high quality. Thanks very much.
