FEP Encapsulated O Rings
O-Ring with a FEP or PFA outer layer encapsulating a Silicone core. The offers excellent chemical and temperature resistance while the Silicone core provides the resiliency needed to provide effective sealing. Readily available in common USA and metric cross-sections and nearly unlimited diameters. FEP encapsulated Solid Silicone with improved chemical resistance up to 205℃. PFA encapsulated Solid Silicone up to 260℃.
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
Encapsulation Options
· FEP Encapsulation
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.
· 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 moulding process.
Silicone Inner Core Encapsulated o ring
Commercially best material option combined with lower Shore Hardness and greater elasticity than FKM, providing an excellent material choice for the majority of applications.
FKM Inner Core Encapsulated o ring
Greater chemical resistance than Silicone. If encapsulation is damaged,FKM provides greater resilience to chemical attack.




1. Name: SIL/ Silicone/ VMQ
2. Raw Material supplier: "Dow Corning" and "Wacker"
3. Working Temp.: -60 ℃ to 230 ℃
4. Advantage:
Excellent resistance to Low temp. heat and elongation;
