Description

Ensure strong, sealed electrical connections with this 310 piece waterproof solder seal connector kit. Designed for quick, secure, and weather-resistant wiring, each connector features a heat shrink sleeve with built-in solder ring and hot-melt adhesive lining, delivering a firm bond and excellent insulation in a single step.

This comprehensive kit includes four sizes of solder seal butt connectors, colour-coded for easy identification, and an additional 210-piece set of black heat shrink sleeves for general cable insulation. The transparent sleeves allow for visual inspection during installation, ensuring proper positioning and sealing.

Ideal for automotive wiring, marine projects, aerospace, DIY electronics, and other outdoor or harsh-environment applications, these connectors eliminate the need for tape or crimping tools, making wire repair and splicing faster and more reliable.

Features:

  • One-step solder and seal design – Combine soldering, sealing, and insulating in a single operation using a heat gun.

  • Waterproof and corrosion-resistant – Inner hot-melt adhesive and heat shrink outer layer form a tight seal, preventing water ingress.

  • Transparent sleeve for inspection – Allows easy visual confirmation of wire positioning and solder flow.

  • Colour-coded sizes – Identify the correct connector by standard colour coding: red, blue, white, yellow.

  • Multipurpose use – Perfect for car repairs, boat wiring, industrial machinery, outdoor lighting, and more.

Specifications:

  • Material: Polyolefin tubing + low-temp solder + hot-melt adhesive

  • Heat Shrink Ratio: 2:1

  • Waterproof Rating: IP67 equivalent (sealed when fully shrunk)

  • Connector Sizes:

    • Red (22–18 AWG / 0.5–1.0 mm²) – 35 pcs

    • Blue (16–14 AWG / 1.5–2.5 mm²) – 30 pcs

    • White (26–24 AWG / 0.25–0.34 mm²) – 25 pcs
