Heatshrink Solder Sleeves - Waterproof Solder Seal Connectors, White, Red, Blue & Yellow

Heatshrink solder sleeves join, insulate and seal a wire splice in one step, with no crimpers or soldering iron needed. Slide the stripped wires into the sleeve and warm it with a heat gun: the solder ring melts into the strands while the adhesive lined sleeve shrinks and seals the joint at both ends, keeping damp out and holding firm under vibration.

Colour - Wire size
White - 26-24 AWG (approx. 0.13-0.2mm²)
Red - 22-18 AWG (approx. 0.33-0.82mm²)
Blue - 16-14 AWG (approx. 1.3-2.1mm²)
Yellow - 12-10 AWG (approx. 3.3-5.3mm²)

Type
Adhesive lined 2:1 heatshrink sleeve with central solder ring

Please note
Use a proper hot air gun and keep heating until the solder has visibly flowed and gone shiny through the joint. A sleeve that has shrunk but whose solder hasn't flowed may look finished, but the joint isn't made.

Applications
Automotive loom and harness repairs, lighting and sensor wiring, trailer and towbar work, marine and caravan electrics, and awkward-access repairs where crimpers won't fit.

Also known as solder seal connectors, solder seal butt connectors, heat shrink solder connectors, waterproof solder connectors or solder splice sleeves.

Supplied in packs of 2, 10, 25, 50 or 100. For a mixed set, see our 100pc assorted solder sleeve box.
