Waterproof solder-seal heat shrink butt connectors provide a one-step solution to join wires with solder, insulation, and a waterproof seal.
They are suitable for outdoor and vehicle electrical projects where moisture and exposure to the elements are a concern.
- One-step solder seal: The connector performs soldering, insulation, and sealing in a single action when heat is applied.
- Waterproof construction: Outer polyolefin heat-shrink tubing with an inner hot-melt adhesive creates a moisture barrier for reliable joints.
- Durable build: Heat-shrink outside with internal adhesive enhances strain relief and resistance to wire pullout during movement.
- Size options and quantities: White SST-S11 26–24 AWG (0.25–0.5 mm2) x 25; Red SST-S21 22–18 AWG (0.5–1.0 mm2) x 35; Blue SST-S31 16–14 AWG (1.5–2.5 mm2) x 30; Yellow SST-S41 12–10 AWG (4.0–6.0 mm2) x 10.
- Compatibility and usage: Designed for copper wires within the listed gauges; heat with a compatible tool to ensure full shrinkage and seal.
Fit: these color-coded connectors cover common copper wire sizes from 26–24 AWG up to 12–10 AWG, making color matching straightforward for quick, reliable wiring repairs.
