DWT(4000) ADHESIVE-LINED SEMI-RIGID HEAT SHRINKABLE DUAL-WALL TUBINGS
CB-DWT(4000) ADHESIVE-LINED SEMI-RIGID HEAT SHRINKABLE DUAL-WALL TUBINGS 
CB-DWT(4000) is adhesive-lined, semi-rigid polyolefin heat shrink dual-wall tubing. It has good mechanical strength and fray-resistance for wire harness terminals and features thicker adhesive for excellent an seal against fluid and moisture. CB-DWT(4000) is specially designed for use on automotive lines, stress relief on wire harnesses, and anywhere oil resistance and abrasion protection are required.
