ISO 9001 Certified Factory. Highest quality. 1 year Warranty
Heavy Duty flashback arrestor set of 2 for oxygen/acetylene torch work. Plus, check valve set for the torch end. 1 year warranty. Never connect a torch to acetylene and oxygen tanks without installing a set of flashback arrestors in the hoses at the regulators. 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 flashback arrestors will make it a "never" occurrence. Check valves are only a first line of defense and may not ultimately stop a flashback. Only the flashback arrestors will.
