KWO® Universal F premium

ePTFE joint sealant tape for food and pharma


KWO® Universal F Premium is a joint sealant tape made from 100% pure, monoaxially expanded PTFE and especially suitable for food and pharmaceutical applications.

The exceptional malleability of the ePTFE joint sealant tape can compensate for out-of-parallel or damaged sealing surfaces and allows use with stress sensitive connections and applications where only a limited flange load is available.

KWO® Universal F Premium is the universal sealing solution on a roll, which can instantly be formed in place to fit any shape, regardless of flange size or complexity.
