120-Piece Heat Shrink Butt Connector Kit

This 120-piece assortment supplies four colour-coded sizes in a durable case for automotive, marine and general electrical work. It covers wire gauges from 26 to 10 AWG with 10 white, 64 red, 36 blue and 10 yellow connectors. UL Listed components meet recognised safety standards. The kit keeps the right size on hand for professional technicians and DIY enthusiasts alike.

Build Quality and Daily Use

Each connector uses a tinned copper core for maximum conductivity and a strong mechanical grip that resists pull-out. The 3:1 shrink ratio tubing carries heat-activated adhesive that forms a waterproof, flame-retardant seal when heated. Thick outer tubing prevents burn-through during installation, while the sealed splice withstands vibration, salt water and harsh weather. The compact case organises sizes for quick identification on the job.

AWG 26-10 Range Decides Fit

The product spans 26 to 10 AWG across four discrete sizes, so the wire gauge you are splicing determines whether this kit covers the job. Buyers working with conductors outside this range will need a different solution. No other specifications limit the application.

Questions about this item

What wire gauges does the UL-listed heat-shrink butt connector kit cover?

The kit covers four colour-coded ranges: white for 26-24 AWG, red for 22-16 AWG, blue for 16-14 AWG and yellow for 12-10 AWG.

What are the barrel dimensions and case footprint so I can check tool clearance?

Each connector has a 3:1 shrink-ratio barrel sized for its AWG range; the durable case holds all 120 pieces in four labelled compartments.

How do I install these connectors and which step causes most failures?

Strip the wire, insert into the tinned copper barrel, crimp firmly, then apply heat evenly until the adhesive-lined tubing fully shrinks — skipping the crimp or uneven heating causes pull-outs or burnt tubing.
