The ES-CAP-NO.2-B9-0-30MM is a heat-shrinkable Sealing Cap made of semi-rigid adhesive-lined polyolefin. It is specifically designed to provide mechanical and environmental protection of stub splices in electrical harnesses. The radiation-cross-linked polyolefin outer jacket is mechanically tough, providing abrasion protection. The cap's inner layer is unique hot-melt adhesive, specially formulated to seal to most types of commercial wire insulation and to perform well at an extended temperature range. The thick adhesive forms an effective barrier against fluids and moisture, helping protect the harness from the effects of corrosion and water wicking.
