FEP/PFA/PTFE encapsulated silicone o ring

1.PTFE FEP/PFA encapsulated O Ring are designed to combine the sealing properties of the rubber O Ring with the chemical resistance of PTFE.

2.They are generally manufactured rubber or silicone rubber and are coated in a thin molded layer of FEP or PFA. 

3.This provides a unique seal popular for high friction and aggressive chemical applications. FEP encapsulated O-Rings are our most common and are resistant to solvents and chemicals.

4.They have a low coefficient of friction and a very low permeability to gases making them suitable for harsh environments. 

5.PTFE Encapsulated O Ring also have a good elastomeric memory.



1.Excellent chemical resistance, is suitable for almost all chemical medium (strong oxidation, reducing solvent);

2.Good corrosion resistance ( Strong acid and alkali solvent );

3.Wide temperature range -200°C~260°C;

4.Good compression resistance ≥30%; 

5.Low Coefficient of Friction (only 0.1 ~ 0.2); 

6.Good resistance to dissolve (≤0.1%) ;  

7.High pressure resistantance(up to 60Mpa ); 

8.Excellent sealing persistence , increase 500% life time.
