FEP encapsulated O-ring
A FEP envelope with elastomer core – the perfect combination of chemical resistance and dimensional stability
FEP-O-SEAL® seals ideally combine the elastic properties of elastomer O-rings with the chemical resistance of FEP (fluoroethylene propylene). FEP-O-SEAL® O-rings consist of two components: a seamless FEP envelope and an elastomer core that guarantees dimensional stability. The FEP Cover is FDA-compliant, conforms to EC 1935/2004 article 3, 3-A Sanitary Standard, USP Class VI and is ADI free. The FEP-encapsulated O-rings have a core of VMQ or FKM and can be ordered from stock.
Advantages of FEP-O-SEAL® O-Rings
- extremely high chemical resistance against most liquids and chemicals
- Temperature range: operating temperatures from -60°C up to +250°C (depending on the core material)
- good resistance to pressure, compression and deformation
- low steam permeability and minimal water absorption combined with low cold flow compared to PTFE
- durability and reliable service
- economical maintenance costs
- compatibility with foodstuffs
- non-adhesive smooth surface
Fields of use of FEP-O-SEAL® O-Rings
FEP-O-SEAL® O-Rings are used in a wide variety of applications in many industry sectors, but in particular, where ordinary elastomers fail due to aggressive fluids and chemicals.
