Premium Components -Wirefy heat shrink butt connectors are crafted from high quality tinned copper barrels in combination with dual wall heat shrink tubing with adhesive inside. These electrical connectors ensure strong crimps, and seal any wire from the elements.

High Quality Thick Copper Barrels - Wirefy butt connectors use thick copper barrels. Once a crimp is done, your wire will not pull out of these butt connectors. Have confidence in every connection you make.

Easy Application - Just make a crimp and apply heat. These wire connectors shrink easily using a heat gun, and create an airtight seal. Marine grade adhesive seals the ends making your connection entirely waterproof.

100% Money-back Guarantee - We want you to be absolutely pleased with our heat shrink butt connectors. If you're not satisfied, return them to us for a fast, no-hassle refund or product replacement.
