Oil Resistant Buna-N U-Cup Seals

15 products

Buna-N U-Cup Seals are resistant to oils, fuels, and greases – plus mild chemicals and water. U-Cup seals are well suited for dynamic applications as they create less friction and are highly resistant to wear. Having a sealing lip on both the ID and OD, they can be used for rod or piston sealing. Commonly used in linear motion applications.
