- Double Lip Protection: Engineered with a primary spring-loaded sealing lip for maximum oil retention and a secondary auxiliary dust lip that acts as a robust shield against external contaminants.
- Chemical Resistance: Optimized for resistance against modern engine and transmission lubricants containing aggressive additives, preventing premature hardening of the seal.
