500 sealed solder wire connectors, heat-shrink sleeves for self-soldering electrical terminals, suitable for automotive and marine applications

This pack of 500 sealed solder wire connectors combines industrial reliability with ease of application. Comprising 200 red connectors (0.5–1.0 mm²), 180 blue connectors (1.5–2.5 mm²), 80 white connectors (0.25–0.34 mm²), 40 yellow connectors (4.0–6.0 mm²), and 340 black heat-shrink sleeves, it covers all common electrical needs in automotive, marine, and light industrial applications. Each connector incorporates a hot-melt adhesive activated at ≥138 °C and a high-strength PE material, offering 2:1 recovery, a 1 kV dielectric strength, and IP67-certified sealing. Meeting electrical safety requirements (max. voltage 600 V), it is designed for demanding environments—including engine compartments, boat hulls, and installations exposed to the elements. Its use requires neither traditional welding nor complex tools: a heat gun is sufficient to obtain a watertight, insulated and mechanically robust connection in a few seconds.
