KWO® MultiTex® Ring 2.0

ePTFE flat gasket


KWO® MultiTex® Ring 2.0 is produced from 100% multidirectional expanded PTFE without any pigments, inks or adhesives, and therefore suitable for clean applications especially for food and pharmaceutical applications.

The flexible material adapts well to sealing surfaces, compensates irregularities and seals at very low stresses.

Suitable for use in metallic flanged, as well as stress sensitive connections.
