 FEP encapsulated O-Rings |
DESCRIPTION
The simple shape of a rubber O-Ring with the chemical resistance of a fluorinated polymer. A fulfilling alternative choice to FFKM O-Rings.
A reliable sealing solution for the chemical, pharma and food processing industry. |
- FDA Approved
- Available in any diameter
- Temperature range
- -25 + 200 °C with FPM core (fluorinated rubber)
- -50 + 200°C with MVQ core (silicone rubber)
- Good compression set
- Wide chemical resistance
- Low friction coefficient
- Don't stick to the surfaces
- No ageing
- Static applications (recommended), and slow non demanding dynamic applications

GROOVE DESIGN AND ASSEMBLING
- Unlike elastomeric ones, FEP encapsulated O-Rings show poor diametrical elasticity, consequently they must be ordered according with the actual groove dimensions.
- For the same reasons, open groove assembling should be preferred.
The closed groove assembling (not suggested) requires pre-heating in water/oil bath; a preliminary test is strongly recommended.
