Oil Pressure Regulator 40-psi 4an ORB Ports

The Oil Pressure Regulator 40-psi 4an ORB Ports by TURBOSMART USA is a precision fluid management component engineered for high-performance fuel and oil systems in modified vehicles, racing engines, and custom turbocharged applications. This regulator maintains consistent pressure at 40 psi, protecting critical engine components from overpressure damage while ensuring stable delivery of fuel or oil under varying load conditions. Whether upgrading a forced-induction setup or refining an existing fuel system, this regulator delivers the reliability demanded by enthusiasts and professional builders.

Built from black anodized aluminum, the Oil Pressure Regulator 40-psi 4an ORB Ports features dual 4 AN female O-ring boss (ORB) ports for inlet and outlet, accommodating -4 AN hose fittings without adapters. A 1/8 inch NPT gauge port allows direct connection of a mechanical oil pressure gauge for real-time system monitoring. The regulator maintains bypass capacity to manage excess pressure, automatically diverting fluid back to the tank or reservoir when system pressure exceeds the 40 psi threshold. The included mounting bracket enables secure installation in engine bays with space constraints, while the compact 3.45 x 2.15 x 4.45 inch footprint fits seamlessly into most custom plumbing layouts.

This regulator is ideal for builders installing remote oil coolers, upgrading fuel delivery systems on boosted engines, or adding secondary oil supply to turbochargers and superchargers. The 40 psi setting is compatible with stock and modified fuel pumps while providing margin for pressure spikes during high-load acceleration. Installation requires AN hose routing from the pump or pressure source through the inlet port, with the outlet directed to the cooler, gauge, or return line. Weighing just 0.28 lbs, it adds minimal mass while delivering maximum control over system pressure stability.
