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 is also suitable for use in the food and pharmaceutical industries due to its approvals.

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.
