Victor Regulator Mount Check Valve Pair (Oxygen & Fuel)

Stay Safe with Victor Regulator Mount Check Valves

Safety is the number one priority when working with oxy-fuel torches, and the Victor 0690-0012 Check Valve Pair is your first line of defense against dangerous gas mixing. This kit comes with two high-quality brass valves—one for your oxygen regulator and one for your fuel regulator. Their job is simple but critical: they let gas flow out to your torch but slam shut the instant gas tries to flow backward. This prevents gases from mixing in your hoses or regulators, which is the main recipe for dangerous flashbacks and explosions.

Installation is a breeze. These valves screw right onto the outlets of your regulators (where you normally attach your hoses). They use the standard B-size fittings (9/16"-18) found on almost all professional welding gear, so you don't need any adapters. Once installed, you simply screw your hoses into the back of the check valves. The solid brass construction means they are tough enough to handle the shop environment, and the internal high-flow design ensures you still get the pressure and volume you need for cutting and heating.

Don't take chances with your setup. Whether you are using acetylene, propane, or propylene, these check valves are a must-have upgrade for any regulator that doesn't have them built-in. They are a small investment that provides peace of mind every time you light the torch. Remember, check valves stop gas flow, but for maximum safety, consider pairing them with flash arrestors to stop flames as well.
