120-Piece Heat-Shrink Connector Kit

This 120-piece kit supplies insulated, waterproof butt splice terminals for wire gauges from AWG 24 to AWG 10. It is aimed at DIYers, automotive technicians and marine installers who need reliable, sealed crimp connections. The assortment covers four colour-coded size ranges in a single package.

UL-Listed With 3:1 Dual-Wall Tubing

Each connector carries a UL listing and uses a tinned copper barrel that resists corrosion and prevents the barrel from opening after crimping. The dual-wall heat-shrink tubing has a 3:1 shrink ratio and a heat-activated sealant lining that creates a 360-degree waterproof, flame-retardant seal suitable for underground use.

Crimp And Heat To Complete The Seal

A crimping tool and a heat gun are required to compress the barrel and activate the adhesive-lined tubing. Once shrunk, the joint is waterproof and mechanically strong, freeing the installer from tape, liquid sealant or separate heat-shrink sleeving. The colour-coded barrels simplify size selection on the job.
