O-RING (Yale YT218K358)

YT218K358: A damaged O-ring can allow fluid or gas to leak past a sealed joint, reducing system pressure and causing component inefficiency. During inspection, an O-ring may show hardening, cracking, or flattening that compromises its sealing ability. This aftermarket replacement part is cross-referenced to Yale part number YT218K358. The O-ring functions as a deformable seal that compresses into a groove to block leakage between mating surfaces. A failed O-ring often leads to gradual loss of lubricant or coolant, which can accelerate wear on adjacent moving parts. Keeping an O-ring in sound condition helps maintain consistent sealing force under static or dynamic pressure. Verify the serial number or application, then call (562) 693-7748.
