Elumen8 adhesive-lined heatshrink tubing in a 50.8mm (2″) supplied diameter with a high 3:1 shrink ratio, supplied as a 1.2m length. This is dual-wall sleeving for sealing and insulating large cable joints, multicore breakouts and connector backshells where a watertight, strain-relieving finish matters more than a straight insulator would give. Aimed at cable techs, riggers and installers working on touring looms and outdoor rigs.

Features
3:1 shrink ratio recovers to roughly one third of its supplied diameter, so one size covers a wide range of cables and joints
Dual-wall construction with a hot-melt adhesive inner liner that flows when heated to fill voids and seal out moisture and dirt
Bonded, moisture-resistant seal suited to outdoor and touring cable work
Adhesive lining grips the cable jacket for strain relief and stops the sleeve creeping under repeated flexing
Tough polyolefin outer wall adds electrical insulation and abrasion resistance over the joint
Recovers evenly with a standard hot air gun, shrinking snugly around irregular shapes and stepped joints
Clear finish lets you inspect the joint and read cable markings through the sleeve
Ideal for large connector backshells, multicore breakouts and field repairs, backed by a 1 year Elumen8 warranty
