FEP encapsulated O-ring
A FEP or PFA envelope and an elastomer core - the perfect combination of chemical resistance and dimensional stability
FEP-O-SEAL® seals combine the elastic properties of elastomer O-rings and the chemical resistance of FEP or PFA in an ideal way. FEP-O-SEAL® O-rings consist of two components: a seamless envelope of FEP or PFA (1) and an elastomer core (2) which guarantees dimensional stability. The FEP Cover is conform to FDA, EC 1935/2004 article 3, 3-A Sanitary Standard, USP Class VI and ADI free. The FEP-encapsulated
O-rings, which can be ordered from stock, have a core of VMQ or FKM.
Advantages of FEP-O-SEAL® O-Rings
- extremely high chemical resistance against most liquids and chemicals
- great range of possible 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 minimum water absorption combined with low cold flow compared to PTFE
- durability and reliable service
- saving in 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.
