Regulators

Pressure Regulators — New & Used
Pressure regulators precisely control and stabilize downstream pressure in pneumatic, hydraulic, and gas systems. Designed to maintain consistent flow regardless of supply fluctuations, regulators are essential for ensuring system safety, equipment longevity, and process accuracy. Available in air, gas, and liquid service types, they support a wide range of industrial and laboratory applications.
At Surplus Select, we carry a rotating selection of new and used OEM pressure regulators from leading brands like Parker, Norgren, SMC, Watts, Fairchild, and Fisher. Our inventory updates daily, offering surplus pricing on precision regulators for MRO, OEM builds, and system upgrades.
