PLUG - HYDRAULIC W/O-RING (Hyster HY0197571)

A damaged retaining ring can allow a hydraulic plug to loosen under pressure, leading to fluid leaks. The Hyster catalog reference HY0197571 identifies this aftermarket replacement part as a PLUG - HYDRAULIC W/O-RING. Its general function is to seal a hydraulic port, with the O-ring providing a static seal against fluid escape. A plain mechanical function is that the plug threads into a port to block flow. A concrete generic failure consequence is that a missing or worn O-ring can cause gradual fluid loss, reducing system pressure. This item ships at approximately 0.1 POUNDS.
