Seal every 12V connection in your build with marine-grade, glue-lined heat shrink — sold as a full 12 metre roll so you never run short mid-job.

Benefits:
• Adhesive lining melts and seals — keeps moisture and road vibration out of crimped joints.
• 3:1 shrink ratio — slides over crimp connectors, then clamps tight onto the wire behind them.
• Full 12m roll — a fraction of the per-metre cost of pre-cut retail packs.
• 4.8mm supplied size suits the small-gauge wiring that makes up most of a van's 12V loom.
• Dual-wall construction — tough flame-retardant polyolefin outer, heat-activated glue inner.
• Cut exactly the length you need — zero waste.

Features:
Dual-wall adhesive-lined polyolefin tubing, 4.8mm supplied diameter recovering to approximately 1.6mm (3:1 ratio), black, supplied as a 12 metre roll. Shrink with a heat gun on low–medium heat, keeping the gun moving for an even finish; a small bead of adhesive at each end of the tube confirms a full seal.

For battery cables, lugs and larger joins, use the 9.5mm roll instead.

Pairs perfectly with our 12-Way Fuse Block and 16-Way Busbar when wiring up your distribution panel.

People are asking

What wire sizes does 4.8mm heat shrink suit?

With a 3:1 ratio it shrinks from 4.8mm down to roughly 1.6mm, so it covers most single automotive wires from about 1mm2 to 4mm2 plus small crimp connectors and butt joins - the bulk of the 12V wiring in a campervan build.

Why use glue-lined heat shrink instead of standard heat shrink?

The inner adhesive layer melts as the tube shrinks and flows around the joint, sealing out moisture and locking the connection against vibration. In a van that lives on the road and gets condensation in winter, glue-lined shrink is what stops corroded joints and intermittent faults years down the track.

How do I shrink it properly?

Use a heat gun on a low-to-medium setting and keep it moving around the tube so it shrinks evenly. You know the seal has taken when a small bead of adhesive shows at each end of the tube. Avoid holding heat in one spot, which can scorch the outer wall.
