100-Piece Blue Waterproof Solder Seal Connectors

This pack contains one hundred blue heat-shrink butt connectors rated for 16-14 AWG wire. Each sleeve holds a solder ring and dual-wall tubing with hot-melt adhesive so a single heat-gun pass creates a sealed, insulated joint. They suit automotive, marine and general electrical wiring tasks where moisture resistance matters.

Sustained environmental sealing

The adhesive-lined tubing shrinks at a 2:1 ratio and bonds to the wire insulation, maintaining a waterproof and dust-proof barrier through vibration, temperature cycling and immersion. The internal solder ring reflows evenly to form a solid metallic bond that does not loosen under long-term mechanical stress.

Heat-gun installation, no crimper needed

Strip the conductors, insert them into the sleeve until they meet the solder ring, then apply heat until the solder flows and the tubing shrinks tight. Common errors are insufficient heat leaving cold solder, or overheating that burns the adhesive; both are avoided by moving the gun evenly along the sleeve.

Questions about this item

How much heat does the solder sleeve need to shrink and seal properly?

A standard heat gun provides enough heat to activate the solder and shrink the tubing in a single step.

What wire gauges can I use with these 16-14 AWG blue connectors?

They accept stranded or solid wire from 16 AWG up to 14 AWG.

Will the adhesive liner bond to older PVC-insulated wire jackets?

Yes, the hot-melt adhesive flows into the insulation texture and forms a waterproof seal on PVC jackets.
