We keep most Silicone FEP O-Ring sizes in stock, however, please contact us to confirm your delivery date.

Silicone FEP Encapsulated O-Rings comprise of an elastomer core which has been seamlessly encapsulated in a jacket of Teflon® fluroropolymer. The core is Silicone and the jacket is FEP. The main advantage Encapsulated O-Rings have over solid PTFE O-Rings is that they can return to the O-Ring's original form due to its energising core.

FEP Encapsulated O-Rings are recommended for use in:
– Automotive Components
– Aerospace Engineering
– Chemical Processing and Production
– Oil Extraction (onshore and offshore)
– Petrochemical Refining
– Pharmaceutical Production
– Food / Drink Processing
– Paint / Die Manufacturing
– Cosmetics and Perfumery

We do not recommend FEPs where the housing design requires excessive stretch or collapse of the O-ring during installation.

Eastern Seals can provide practically any size of encapsulated rings, with many Silicone BS315 – BS395 sizes held in stock. We can offer both solid and hollow core styles. They are available in Cross Sections from 1.78mm to 25.4mm – the only limits to size are with the smaller ID’s
