Wire Solder & Heat Shrink
Make clean, waterproof connections for car wiring jobs
Solder seal connectors and heat-shrink tubing make strong, waterproof joints when wiring dash cams, lights, stereos, or repairs. Solder-and-seal butt connectors melt and seal with a heat gun in seconds, giving a tidier, more reliable joint than crimps alone.
We compare solder seal connector kits and heat-shrink assortments on Amazon. Look for marine-grade adhesive-lined tubing and a range of wire gauges.
