Superior Thermal Stability: The FPM (Fluorocarbon Rubber) compound is engineered to maintain sealing integrity at significantly higher temperatures than standard NBR, ideal for high-stress drivetrain and engine zones.
Chemical Additive Resistance: Offers exceptional resistance to aggressive synthetic fluids, specialized lubricants, and chemical additives, preventing lip hardening and ensuring a leak-proof interface.
Integrated Dust Protection: Features a secondary sealing lip designed to block the ingress of dust, dirt, and moisture, protecting the primary sealing interface from premature wear.
Precision Dual-Height Fit: The 6/6.5 mm architecture ensures accurate axial positioning and a superior seal against the housing bore, preventing oil migration and leaks.
Optimized Radial Pressure: Engineered specifically for 40 mm shaft diameters to provide consistent sealing force with reduced friction, enhancing the efficiency and longevity of the rotating assembly.
