FEP encapsulated silicone seal

An Encapsulated 'O'-Ring is an 'O'-Ring bound by a seamless and uniform FEP/PFA encapsulation, which encloses an elastomeric core, completely protecting it from the media. They combine the energising properties of an elastomeric 'O'-Ring with the resilience to extreme temperatures and hostile chemicals of FEP/PFA.

Benefits of Encapsulated Seals

• Exceptional resistance to aggressive chemicals and gas permeability
• Cost efficient alternative to Kalrez^® and similar perfluoroelastomer 'O'-Rings
• Low coefficient of friction allowing reduced wear of equipment
• Adaptive sealing force of an elastomeric 'O'-Ring
• Resistant to compression set/cold flow issues of solid 'O'-Rings
