FEP ENCAPSULATED O-RINGS / PFA
FEP encapsulated O-rings comprise an elastomer core which has been seamlessly encapsulated in a jacket of Teflon fluoropolymer. The core is either Viton, Silicone or EPDM. The jacket is FEP or PFA.
FEP encapsulated O-rings are recommended when a standard O-ring has inadequate chemical resistance for an application. They are also recommended when a solid PTFE O-ring does not have the elasticity for reliable, long-term fluid sealing. They are often used where chemical resistance and or hygiene is required.
Typical industries include:
FEP cross section optionsHollow core silicone Encapsulated O-Rings have greater compressibility compared to solid core O-Rings. The hollow core flexibility means less clamping force is required to enable its sealing abilities.
These O-rings are ideal for fragile applications using sensitive materials, such as glass or light plastics, They are particularly useful for where the sealing area may require room for movement during operation.
FEP encapsulated O-rings offer excellent resistance to a wide range of chemicals. They offer typical temperature ranges of:
• -60°C to +200°C with Silicone core.
• -20°C to +200°C with Viton core.
They offer low friction and a low ‘stick-slip’ effect.
PFA encapsulated O-rings offer extra abrasion resistance. When combined with a Silicone core, they offer a temperature range of -60°C to +260°C.
We also supply PFA encapsulated O-rings with a Viton core. These seals offer a temperature range of -20°C to +200°C. Viton core PFA encapsulated O-rings also provide extra abrasion resistance.
The clear Teflon FEP / PFA encapsulation of our encapsulated O-rings is compliant with NSF 61 requirements.
The outer encapsulate is an FEP or PFA melt process-able polymer of PTFE. PTFE is also known as the brand Teflon. PTFE polymers are highly inert. They are often used in industrial food processing and domestic food cooking equipment.
