Stringent fuel economy and emissions requirements drive the need to reduce friction and other parasitic energy losses while maintaining leak-free performance.
• MicroTorq seal delivers less frictional torque than other seal alternatives
• Lower parasitic friction losses improves fuel economy, driving lower emissions
• Small packaging space of seal enables design flexibility for next-generation engines
• Durability performance consistent with industry application requirements
1. Proven FKM elastomer material provides excellent chemical compatibility
2. Dual-hinge flex section keeps uniform, low friction lip contact around the shaft
3. Static band provides reliable air seal and a continuous fluid barrier
4. Hydrodynamic aids deliver positive fluid pumping with reduced contact pressure
5. Integrated dirt excluder maintains uniform contact by following the shaft
6 Stabilizing ribs enable worry free6. Stabilizing ribs enable worry-free installation without any special tools
