Rego 1/4"FPT in X 1/2"FPT Outlet 1st Stage Red Propane Regulator, 10PSI Output

Rego 1/4"FPT in X 1/2"FPT Outlet 1st Stage Red Propane Regulator

The LV3403TR RegO 1st Stage Propane Regulator is a compact, high-capacity first-stage regulator designed to reduce container pressure to an intermediate pressure of approximately 10 PSIG for propane installations. Built for demanding applications up to 1,500,000 BTU/hr, it features a large flow orifice to help resist freeze-ups, a piped-away capable bonnet vent for underground installations, and built-in safety features that comply with NFPA 58 overpressure requirements.

Country of Origin
