  • 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.
  • Smiths reverse flow check valves close automatically when outlet pressures drop below 1/2 PSIG, preventing reverse flow of gases.
  • Outlet Connection: 9/16-18 LH & RH Internal
  • Inlet Connection: 9/16-18 LH & RH External
