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.

FAQ

Are solder seal connectors reliable?
Yes, when heated properly they create a soldered, sealed joint that resists moisture and vibration.
Do I need a heat gun?
A heat gun gives the best results. A lighter can work but risks scorching.
What gauge do I need?
Match the connector color or size to your wire gauge, often marked on the kit.
