Produktdata

Operational application limits

Temperature FKM: -15°C to +200°C

Media

Good chemical resistance to mineral oils and greases, synthetic oils and greases, engine, transmission and ATF oils up to approx. +150°C, fuels, flame-resistant hydraulic fluids HFD, aliphatic, aromatic and chlorinated hydrocarbons, water up to max. +80°C, excellent resistance to weather, ozone and ageing, very low gas permeability (therefore suitable for vacuum applications), broad chemical resistance.

Function

By tightening the screws the elastomer sealing lip is compressed, thereby producing the sealing effect on the surfaces to be sealed. It stops the medium from leaking to the outside, thus preventing loss of pressure. In addition, it provides protection against dirt from the outside.
The centring feature of the USS type ensures that the bonded seal is fixed in the correct position for mounting and when tightening the screws, thereby guaranteeing captive mounting.
