Adhesive lined heat shrink tubing, 24 mm shrinking to 8 mm, in 100 mm lengths. A 3 to 1 ratio dual wall tube that seals as well as insulates.
Adhesive lined is a different product from ordinary heat shrink. Plain tube shrinks down and grips, but it does not seal: water tracks along the conductor underneath it, and on a battery or high voltage joint that is exactly where corrosion starts. Dual wall tube carries an inner layer of adhesive that melts as the outer layer shrinks, flows into every gap, and sets. The result is a joint that is sealed against moisture rather than merely covered.
The 3 to 1 ratio is what lets it cover a lug. A joint is almost always much fatter than the cable leading into it, and ordinary 2 to 1 tube that fits over the lug will not close down onto the cable behind it. Going from 24 mm to 8 mm covers both in one piece.

Features
- Adhesive inner wall that melts and flows, sealing rather than just covering
- 3 to 1 ratio, so one piece covers both a lug and the cable behind it
- Cut to 100 mm, the usual length for a cable lug termination
- Insulates and weatherproofs a joint in a single operation
Compatibility
For cable lug terminations, splices and connector backshells where the finished diameter falls between 8 mm and 24 mm.
Use enough heat, and work from the middle out. The adhesive has to reach its melting point, not just the outer wall. Shrink from the centre towards each end so the adhesive is pushed out rather than trapping air, and stop when you see a small bead of adhesive appear at each end. That bead is how you know it has sealed.
It is a one way operation. Adhesive lined tube cannot be slid off and reused, so make sure the joint is right before you shrink it.
