Automotive Wire Harness Tape 0.2mm Woven PET Cloth This tape is made for one job only: wrapping automotive wire harnesses. The 0.2 mm woven polyester backing is dense enough to resist chafing against brackets and body panels, yet thin enough to keep a bundled harness compact when it is routed through a 20 mm conduit or a door grommet. The acrylates copolymer adhesive is coated solvent free, so the roll stays soft on the shelf and still holds on oily, dusty harness surfaces.
