SEAL - PISTON (Yale YT220078919)

A damaged piston seal can allow fluid bypass, reducing system pressure and causing sluggish or incomplete movement. This aftermarket replacement part references the Yale catalog and cross-references part number YT220078919. The seal functions as a dynamic barrier between the piston and cylinder bore, preventing leakage during reciprocating motion. Over time, a worn seal may lead to internal fluid loss and diminished force output. In a typical repair scenario, technicians replace the seal when cylinder drift or reduced stroke speed becomes noticeable. The item ships at approximately 0.015 pounds. Verify the serial number or application, then call (562) 693-7748.
