HST-D 4X Adhesive-Lined 4:1 Heat Shrink Tube (Double-Wall)
Double-wall, adhesive-lined 4:1 heat shrink tube for robust sealing and protection.
Outer cross-linked polyolefin + inner hot-melt adhesive for waterproof, airtight joins.
Operating temp −55 °C to 125 °C; adhesive melt ≈ 70–80 °C; full shrink ≈ 125 °C.
Black as standard; sizes cover common cable repairs, splices, and branch sealing.
Overview
The HST-D 4X series is an adhesive-lined, double-wall 4:1 heat shrink tube engineered for sealing,
waterproofing and corrosion protection. A cross-linked polyolefin outer wall provides durability, while the inner hot-melt
adhesive flows on heating to fill gaps and bond to cable jackets, creating a uniform, solid seal.
With its high shrink ratio, this 4:1 heat shrink tube easily accommodates irregular shapes,
large-to-small transitions, and in-field repairs, delivering clean, professional results on splices and wire branches.
