Adhesive Lined Heat Shrink 4.8mm 3:1 — Black (12m Roll)

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.
