Constructed from high-grade NBR or optional FKM, this shaft seal delivers superior resistance to harsh detergent additives, hot wash liquid, and dynamic mechanical wear. Under continuous exposure to soapy environments, standard polymers often degrade, swell, or lose sealing tension. CFKS elastomer formulations resist thermal hardening across broad temperature swings while providing low-friction operation. This inherent toughness preserves sealing lip integrity, shielding outer tub bearings from fluid contamination and premature corrosion.

Engineered for straightforward repair and overhaul workflows, this 35*75.55*10/12 water seal installs securely into the rear tub housing without dynamic distortion. Proper fitting requires clean shaft seating, a uniform application of waterproof grease within the lip cavity, and gentle, flat press-fitting. The stable outer profile ensures a snug static seal against the tub wall, preventing fluid bypass. Its resilient structure drastically lowers wear rates during high-spin cycles, offering long-term reliability and reducing the need for frequent teardowns.
