Accusump Check Valve 1/2 in npt

The CANTON Accusump Check Valve 1/2 in NPT is a brass check valve engineered for oil accumulator systems where backflow prevention and one-directional fluid control are critical. This component features 1/2 inch NPT female inlet and outlet connections, making it compatible with standard oil accumulator plumbing configurations. Built from brass for corrosion resistance and reliable long-term performance in pressurized automotive lubrication systems, the Accusump check valve ensures oil flows in only one direction, protecting engine oil galleries and accumulator integrity during engine shutdown and startup cycles.

Check valves in oil accumulator circuits serve a specific hydraulic function: they allow pressurized oil to charge the accumulator while preventing backflow when system pressure drops. The 1/2 NPT threading standard ensures compatibility with most aftermarket Accusump accumulator kits and custom engine oiling modifications. Brass construction provides excellent resistance to mineral oil degradation and temperature cycling, critical for applications where oil temperatures regularly exceed 200°F. The compact design—weighing 0.35 lbs—integrates seamlessly into tight engine bay configurations without requiring custom fabrication or adapter fittings.

This check valve is specified for high-performance street engines, racing applications, and vintage restorations where oil starvation during hard acceleration or cornering presents a reliability risk. Drivers upgrading to remote-mounted oil accumulators rely on check valves like this to maintain consistent oil delivery to critical bearing surfaces. The part is essential for any Accusump system installation where the accumulator sits remote from the engine block, as backflow through the oil line during engine shutdown would defeat the accumulator's pressure-maintenance function. Direct replacement for OEM Accusump systems and compatible with most bolt-on accumulator kits.
