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 similar perfluoroelastomer O-Rings

  • Low coefficient of friction allowing reduced wear of equipment

  • The adaptive sealing force of an elastomeric O-Ring

  • Resistant to compression set/cold flow issues of solid O-Rings


Encapsulation Options 

  • FEP Encapsulation
    Standard material for all applications up to 205°C, resistant to virtually all chemicals and joined by an advanced heat molding process to give a seamless encapsulation.

  • PFA 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 molding 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.  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.

Ring Shape Options

  • Although the standard O-Ring shape is circular, we also manufacture other ring shapes to your application needs, such as squarerectangular or oval. The only set condition is that the ring corners have a radius, as opposed to angled at 90 degrees.
