Ross Controls 5212B3017 Air Pressure Regulator

The Ross Controls 5212B3017 is a compact 3/8" NPT air pressure regulator that delivers a stable, adjustable output of 0 to 50 psi for compressed-air systems, making it well suited to precision pneumatic work, small actuators, and tooling that demand consistent pressure control. The unit uses 3/8" NPT inlet and outlet ports with 1/4" NPT gauge ports; the integrated pressure gauge reads 0 to 200 psi, allowing quick verification of the regulator’s set point and actual output in operating conditions. As part of Ross Controls' Full-Size Regulator family, the 5212B3017 is designed for reliable performance in industrial environments, typically installed close to the point of use in control panels or near pneumatic actuators to minimize pressure drop and improve response to load changes. For non-NPT piping schemes, a BSPP-thread variant exists (C5212B3017) that preserves the 3/8" port sizing and 0–50 psi range; the model number clearly identifies the port size and regulation range, aiding cross-reference in catalogs and spare-parts inventories.
