Industrial R353-125 Pneumatic Regulator 125 PSI

Arrow Pneumatics' R353 3/8" NPT air regulator with gauge provides precise downstream pressure control in industrial compressed-air systems, delivering a 5–125 psi output range for reliable actuation of cylinders and tools. The regulator features an aluminum body with a brass valve seat and a self-relieving design, helping to maintain steady pressure and relieve excess downstream pressure when airflow is halted. Rated for up to 250 psi inlet pressure and capable of flows up to 80 SCFM, the R353 uses straight-through ports with 3/8" NPT inlet and outlet connections for straightforward installation. This gauge-equipped regulator is well-suited for automation panels, pneumatic tooling, and general manufacturing applications where accurate, stable pressure is essential. The built-in gauge allows quick verification of the regulated pressure, enabling fast tuning and system diagnostics in daily operation.
