## Description

Heat Shrink Wire Connectors

Review: Nice - Very pleased with these. Make sure you take the time to swap your crimp teeth for the correct ones and these hold fine. They shrink ok.
Review: Brilliant heat shrink crimp connectors - Great set of crimp connectors with adhesive lined shrink wrap ends. Rewired an old 1970's narrow boat with bare wire connections into 6 gang bullet type fuse boxes. Crimps up tight even with small wiring, pull tests surprisingly resilient, heat gun shrinkage glued to the insulation. A new fuse box and all new loop connections made for a much safer setup. My only concern is I've used almost all of one particular size and don't really need to buy another entire range, how do I replace them once they run out? Very easy to use with a quality finish.
