O-RING - CONTROL PISTON (Hyster HY154685)

A damaged control piston O-ring can allow fluid bypass, reducing system pressure and causing sluggish operation. This aftermarket replacement part cross-references Hyster part number HY154685. The O-ring creates a seal between the control piston and its bore, preventing leakage during actuation. Over time, exposure to heat and pressure can cause the elastomer to harden or crack, leading to internal leakage. In a typical repair scenario, a worn O-ring is often discovered when the piston fails to hold position under load. The item ships at approximately 0.001 pounds. Verify the serial number or application, then call (562) 693-7748.
