KWO® Universal F

ePTFE joint sealant Tape

KWO® Universal F is a joint sealant tape made from 100% pure, monoaxially expanded PTFE.
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 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.
Typical applications are the sealing of flanges, pump housings, compressors, hand- and manholes, air ducts and compensators.
