Solder seal sleeves and heat shrink connectors for waterproof joints.
Solder sleeves are heat-shrink tubes with a ring of solder inside, which let you join and insulate wires in one step by heating with a heat gun, without a soldering iron. The solder melts and connects the wires, while the tube shrinks and seals the joint, which makes it waterproof and strong. They are popular for car wiring, boats, motorcycles, outdoor lighting and electronics repairs. Colour-coded sleeves match different wire gauges. Check the wire gauge range and quantity before ordering. Assortment packs include several sizes. A heat gun works better than a lighter for even heating.
