Professional Wire Connector Kit

This 320-piece assortment supplies ring, fork, spade and heat-shrink butt terminals for automotive, marine and general electrical work. The UL Listed components suit technicians and DIYers who need a single kit covering the most common crimp connections.

Heat-Shrink Seal and Conductivity

Adhesive-lined polyolefin tubing melts to form a waterproof barrier around each joint, while the translucent walls allow visual confirmation of the crimp. Premium copper cores deliver reliable conductivity and mechanical pull strength in wet or vibration-prone environments.

Crimp-Ready Terminal Assortment

The kit eliminates the need to source multiple connector types separately, freeing bench space and reducing parts inventory. A standard crimp tool completes every connection; no soldering equipment or specialised hardware is required.

Questions about this item

How do I install the heat shrink butt connectors so the adhesive seals properly?

Strip the wire, insert it fully into the barrel, crimp with a ratchet tool, then apply heat evenly until the translucent tubing shrinks and adhesive flows out both ends.

Will the copper terminals inside the heat shrink tubing corrode over time in a marine environment?

The adhesive-lined polyolefin tubing seals to the wire insulation, blocking moisture from reaching the copper core; inspect the translucent sleeve periodically for cracks.

At what temperature does the adhesive-lined tubing start to shrink and seal?

Standard polyolefin heat shrink begins shrinking around 90 °C; use a heat gun on low setting to avoid scorching the tubing.
