Complete 128-Piece Connector Kit

This marine-grade heat shrink wire connector kit contains 128 pieces covering ring, butt, male, female and fork terminals. The assortment is designed for automotive, household and DIY wiring tasks where reliable, insulated connections are required. Colour-coded sizes simplify selection for the correct wire gauge.

Waterproof Heat-Shrink Technology

Each terminal uses a dual-wall construction with heat-activated adhesive lining and a 3:1 shrink ratio to create a sealed, waterproof joint. The adhesive bonds when heated, blocking moisture, dust and corrosion from the crimped connection. This protection suits marine environments and exposed vehicle wiring.

Suited for Multi-Gauge Repair Work

The kit covers AWG 22-16, 16-14 and 12-10 ranges in red, blue and yellow coding, making it practical for technicians who service mixed-gauge looms. Builders needing high-temperature or non-shrink terminals, or those working outside the listed gauge ranges, should look at alternative connector types.

Questions about this item

Which connector sizes in the 128-piece kit will need replacing if the wire gauge changes from AWG 14 to AWG 10?

The yellow heat-shrink terminals cover AWG 12-10, so moving from blue (AWG 16-14) to yellow handles the thicker wire without new crimp tools.

What is the maximum wire gauge the kit's largest terminal can accept for continuous current?

The yellow terminals are rated for AWG 12-10, making 10 AWG the thickest wire the kit supports for sustained loads.

How much heat does the dual-wall adhesive lining add when all 128 connections are powered continuously?

The heat-shrink tubing activates once during installation; after cooling it adds no ongoing heat, so the connectors run at the same temperature as the bare wire.
