About this item
Product details
Smith Equipment H698 Regulator Mount Reverse Flow Check Valves 1 PairPart # H698Reverse flow check valves are an important part of any oxy/fuel system. Without check valves, reverse flow of oxygen and fuel gases can occur when a tip becomes clogged, or when one cylinder empties during use allowing the higher pressure gas to back up into the other hose and into the regulator, thereby creating conditions 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.Inlet Connection: 9/16"-18 LH & RH Internal Outlet Connection: 9/16"-18 LH & RH ExternalH698 Reverse Flow Check Valves attach directly to the existing regulator outlet fittings.
- Material Brass
- Standards UL Listed
- Series H698
- For use with Regulators
