Keep your gas-powered equipment running smoothly with the BBQHKCX R622H first-stage propane regulator, a robust solution for residential, commercial, and industrial applications. This high-capacity regulator delivers precise pressure control (adjustable from 4–12 PSI) with a factory setting of 8 PSI, ensuring reliable performance for heaters, burners, generators, and outdoor cooking systems.

Designed for LP, propane, and natural gas systems, the R622H features a 3/4″ NPT inlet/outlet and a 7/32″ orifice for seamless integration. Its spring-loaded first-stage design safely reduces high tank pressure, preparing gas for second-stage systems—ideal for commercial kitchens, industrial setups, and high-demand outdoor applications.
