120-Piece Waterproof Solder Seal Kit

This kit supplies 120 heat-shrink solder sleeves that create insulated, waterproof wire splices without a soldering iron. The dual-wall tubing carries heat-activated adhesive so each joint seals against moisture, dust and vibration. UL-listed construction suits marine, automotive and outdoor electrical repairs. Colour-coded sleeves simplify size selection for quick, reliable connections.

DIY installers and field technicians

The assortment covers four colour groups for different wire gauges, making it practical for hobbyists, boat owners and vehicle restorers who need durable, solderless joints on site. Installers who require crimped terminals, non-shrink butt connectors or large-gauge power lugs will not find those styles in this pack. Professional looms demanding mil-spec documentation should verify the UL listing meets their project specification.

120 sleeves in four colour-coded sizes

The package contains 40 red, 35 blue, 35 white and 10 yellow sleeves, each combining a pre-fluxed solder ring with adhesive-lined heat-shrink tubing. A hot-air gun melts the solder and shrinks the tube in one step, delivering a sealed, mechanically strong joint. This count and colour mix determines whether the kit covers the range of wire diameters in your next wiring job.

What comes in the 120-piece kit and what tools are needed to use it?

The kit contains 120 solder sleeves: 40 red, 35 blue, 35 white and 10 yellow. No professional welding equipment is required; a hot air gun is used to heat and seal each connector.

Each colour corresponds to a different wire diameter range. Select the colour that matches the gauge of the wire you are splicing.
