What is FPM / Viton material?

FPM (fluoropolymer elastomer, also known by the trade name Viton) offers excellent resistance to mineral oils, synthetic gearbox fluids, and high operating temperatures, making it the preferred material for gearbox shaft seals.

What does the R23 lip style mean?

The R23 designation indicates a single sealing lip combined with a shaft wiper (dust exclusion lip). The wiper prevents external contamination from entering the gearbox while the primary lip retains the gearbox oil.

What applications is this seal used in?

This seal is used to seal rotating input and output shafts in manual gearboxes and transfer cases. If you are unsure whether this seal fits your application, please contact us with your vehicle registration or VIN.

Can I identify the correct seal by its dimensions?

Yes. Rotary shaft seals are typically identified by three dimensions: inside diameter (ID), outside diameter (OD), and width. This seal is 40x55x8mm. Match these to your existing seal or housing bore to confirm fitment.

Is this seal compatible with synthetic gearbox oils?

Yes. FPM (Viton) elastomer is compatible with both mineral and synthetic gearbox lubricants, including MTF and ATF variants commonly used in manual transmissions.
