Fisher Type R122H LPG First-Stage Pressure Regulator

The Fisher Type R122H Pressure Regulator is a high-performance first-stage regulator designed for use in LPG (liquefied petroleum gas) systems. Engineered for superior overpressure protection, this regulator ensures safe and reliable pressure reduction from the storage tank to the downstream system.

The R122H is built with rugged materials for durability and optimal performance in residential, commercial, and industrial applications. Its compact design and high capacity make it ideal for installations requiring consistent and precise pressure control. The model R122H-AAJ is factory-configured to meet specific pressure requirements for efficient operation.
