The part numbers 3936365, 3902338, and 3927622 ensure compatibility with a broad spectrum of Cummins engine families, including the 4BT, 6BT, 6CT, ISB, QSB, ISC, and ISL series.

Designed for both automotive and industrial markets, this valve meets the rigorous standards of the automotive replacement oil pressure relief valve gasket category, where it ranks #16 in best‑selling performance. Since its launch on July 4, 2022, the product has earned a perfect 5‑star rating from three verified customers, reflecting its reliability and ease of installation. Whether you are servicing a 1989‑2018 Dodge truck equipped with a 5.9L or 6.7L Cummins engine, or maintaining industrial equipment that relies on Cummins power units, this valve delivers consistent pressure regulation and protects critical engine components from over‑pressure damage.

The valve’s design incorporates a dual‑port flow path that distributes oil evenly, minimizing turbulence and ensuring smooth operation under varying load conditions. Its NPT threaded outlet aligns with standard fittings found in most Cummins service manuals, simplifying the replacement process and reducing downtime. The metal construction not only provides durability but also offers superior heat dissipation, helping to maintain stable oil temperature during prolonged operation.

Overall, the Hconcet Oil Pressure Relief Valve combines robust materials, precise engineering, and universal compatibility to provide a dependable solution for maintaining engine health. Its straightforward installation, combined with a proven track record of performance, makes it an essential spare part for mechanics, fleet operators, and industrial maintenance teams seeking to safeguard their Cummins‑powered assets.

Usage

The valve is ideally suited for use in medium to heavy‑duty trucks that rely on Cummins diesel engines, particularly those in the 5.9L and 6.7L displacement range. In these applications, the valve regulates oil pressure during engine start‑up, idle, and high‑load conditions, preventing pressure spikes that could damage bearings, seals, and other internal components. Its dual‑port design ensures that oil flow remains balanced, which is especially important in engines that experience rapid changes in load, such as those used in towing or off‑road operations.

Beyond automotive use, the valve performs excellently in industrial settings where Cummins engines power generators, compressors, and construction equipment. In these environments, the valve helps maintain consistent lubrication, reducing wear on critical moving parts and extending the intervals between major overhauls. The NPT threaded outlet matches the standard fittings on most industrial oil circuits, allowing technicians to replace the valve without needing specialized adapters.

Installation is straightforward: the threaded inlet connects to the engine’s oil pressure line, while the NPT outlet mates with the existing relief line. The compact size permits installation in confined engine bays, and the metal housing provides a secure anchor point that resists vibration. After installation, the valve requires only a routine pressure check during the first service interval to confirm proper operation. Its durability means it can withstand the harsh conditions of desert, arctic, and maritime climates, making it a versatile choice for fleets operating across diverse geographic regions.
