Description

• Without check valves, reverse flow of oxygen and fuel gases can occur when a tip becomes clogged.

• If one cylinder empties during use it can allow the higher-pressure gas to back up into the other hose and regulator, which could lead to a regulator explosion.

• Close automatically when outlet pressures drop below 1/2 PSIG, preventing the reverse flow of gases.

• Outlet Connection: 9/16-18 LH & RH Internal

• Inlet Connection: 9/16-18 LH & RH External
