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
