MultiTex® S 8 – ePTFE Gasket with diffusion barrier
KWO® MultiTex® S 8 is produced from 100% pure expanded PTFE without any pigments, inks or adhesives, and therefore especially suitable for clean applications.
A diffusion barrier ensures very high sealability at very low gasket stress.
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.
Seals most chemicals across the whole pH range (0-14).
