KC Oil Seal

Temperature: -40 - +200℃

Material: NBR, FKM

Color: balck, brown

Application: shaft sealing

1. Description

The KC profile is a shaft seal composed of a single metal cage with a rubber coating, a primary sealing lip without a spring and an additional anti-pollution sealing lip.


2. Materials

NBR (Nitrile Butadiene Rubber)

Nitrile rubber (NBR) is the general term for acrylonitrile-butadiene copolymer. The ACN content can vary between 18% and 50%. While the acrylonitrile content is important, the resistance to oil and fuel is more so. Conversely, the elasticity and compression set are not as good. The NBR has good mechanical properties and good wear resistance. However, its resistance to atmospheric agents and the ozone is relatively low.

FKM (fluorinated rubber)

Depending on their structure and fluorine content, the chemical resistance and resistance to the cold in fluororubbers can vary. This FKM-based rubber is very often used for high-temperature hydraulics and pneumatics, for industrial valves, injection/fuel systems, motor seals and high-vacuum systems.
