Rego 1/2"FPT in X 1/2"FPT Outlet 2nd

The LV4403B4 Rego 1/2" FPT × 1/2" FPT 2nd Stage Propane Regulator is a straight-through second stage regulator designed for installation at the structure to deliver stable downstream pressure for high-demand LP gas systems. It provides 2 PSI delivery pressure (11" water column) at a 10 PSI inlet, supports up to 935,000 BTU output capacity, and features an adjustable outlet pressure range of 1–2.5 PSI. This regulator is intended to be used in conjunction with a 10 PSI first-stage regulator at the tank (such as a compatible Rego first-stage model).
