3:1 Heatshrink

3:1 adhesive lined heatshrink, dual wall tubing with an inner adhesive layer that melts as the tube shrinks, creating a moisture-proof seal over joints, splices, terminals and cable ends. It shrinks to a third of its supplied diameter, so one size covers a wider range of cables and fits over connectors and bulky joints.

Black polyolefin, shrinks at 80°C and rated from -55°C to +125°C, with resistance to fuel, hydraulic fluid and lubricating oil. Available in sizes from 3.2mm to 39mm, in cut lengths, 1.2m sticks or full reels.

Also known as glue lined heatshrink, adhesive heat shrink, dual wall heatshrink, marine heat shrink and waterproof heat shrink tubing.
