FEP/PFA fep encapsulated o-ring, PTFE/FEP/PFA Encapsulated O Rings, PTFE FEP encapsulated FKM FPM o
PTFE Encapsulated 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.
Product Description
| Product name | FEP/PFA fep encapsulated o-ring |
|---|---|
| Material Type | Transparent FEP/PFA Encapsulated silicone/FKM O Ring |
| Color | Available in any color, according to customers' requirements |
| Size | AS568,ISO3601,BS Standard or customized size |
| Working Temperature | FEP Encapsulated O-rings: -60℃ to 205℃ (260℃ short term) PFA Encapsulated O-rings: -60℃ to 260℃ (300℃ short term) |
