Viton O-Ring - Crank Pulley Hub Bolt (12A, 13B, 20B) [Single]

Single Front Crank Pulley Hub O-Ring for all Mazda Rotaries.

Being a Viton material allows these O-rings to be reused with confidence and are resilient against a wide range of chemicals including engine oil, alcohol, methanol, and ethanol.

Most OEM and aftermarket replacement O-rings are made of Buna-N (Nitrile Rubber) which deform over time due to normal heat-cycling of the engine. This can become a problem as they will start to lose sealing ability and can start to leak or fail completely.
