FEP/PFA Encapsulated 'O'-Rings and Seals
Benefits of Encapsulated 'O'-Rings and 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
Standard material for all applications up to 205°C, resistant to virtually all chemicals and joined by an advanced heat moulding process to give a seamless encapsulation.
Same properties as FEP encapsulation but with greater heat resistance for applications above 205°C. Also resistant to virtually all chemicals and joined seamlessly via advanced heat moulding process.
Inner Core / Profile Options
Silicone Inner Core
Commercially best material option combined with lower Shore Hardness and greater elasticity than Viton®, providing an excellent material choice for the majority of applications.
Viton® Inner Core
Greater chemical resistance than Silicone. If encapsulation is damaged, Viton® provides greater resilience to chemical attack.
Silicone Hollow Inner Core
Greater compressibility than solid Silicone core, with a hardness similar to a standard elastomeric 'O'-Ring. The hollow core flexibility means less clamping force is required to enable its sealing abilities. Ideal for fragile applications using sensitive materials, such as glass or light plastics. Useful for where the sealing area may require room for movement during operation.
Silicone/Viton® Square/Rectangular Core
Designed to be a gasket seal, as opposed to an 'O'-Ring. In particular, the rectangular cross-section is designed to be a universal fit, It eliminates the need to specify different elastomers for different applications and stops coupling leakage due to chemical attack or creep of a solid PTFE gasket seal.
Custom Core Profile
We also manufacture special custom profile and ring shapes to your application needs.
