DWFR tubing from TE Connectivity (TE) is a highly flame-retardant, high-shrink ratio, adhesive-lined tubing made from a polyolefin jacket with a thermoplastic adhesive inner wall. It insulates and environmentally seals and protects components and other electrical connections and terminations. DWFR’s medium wall thickness provides increased mechanical protection. Its high shrink ratio allows DWFR to cover a variety of substrates with a limited number of tubing sizes. It is suitable for sealing and protection of connector-to-cable transitions and repairing damaged cable jackets. It can also be used to create and seal breakouts in harnesses.
