SEAL (Yale YT220161645)

A worn seal can allow fluid leakage, leading to reduced system pressure and eventual component failure. This aftermarket replacement part references the Yale catalog number YT220161645. The seal functions as a static or dynamic barrier between two mating surfaces. Its primary mechanical role is to prevent the passage of fluids or contaminants under normal operating conditions. A common failure consequence is gradual loss of lubricant, which accelerates wear on adjacent moving parts. In a typical usage context, seals are exposed to temperature cycles and pressure variations that can degrade elastomeric materials over time. Verify the serial number or application, then call (562) 693-7748.
