Suburban Mfg 523003 Vertical Vent Two-Stage LP Gas Regulator

Suburban Mfg 523003 is a combination two-stage propane regulator designed to control the flow of LP gas to all appliances in your RV or motorhome. The two-stage design first reduces cylinder pressure down to 10 psi, then a second stage maintains a stable, consistent working pressure of 11 inches water column at the appliance — ensuring reliable performance regardless of tank fill level or ambient temperature.
