Viton O-Ring Set - Dowel Pin (12A, 13B) [Set of 4]

Set of four Dowel Pin O-Rings for a 2-Rotor Engine.

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, and ethylene glycol.

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 lead to oil leaks or complete failure.

Replaces OEM Mazda part number: N3A1-10-B73
