Waterproof Automotive Marine Electrical Insulated Self-Solder Seal Butt Connectors

Ultra-Reliable Self-Solder Design
Patented heat-activated solder ring ensures instant, gas-tight connections without extra tools. Tin-plated copper core maximizes conductivity and corrosion resistance.
Military-Grade Waterproof Protection
Dual-wall adhesive-lined heat shrink tubing with IP68 rating blocks moisture, salt, and chemicals. Ideal for marine, off-road, and outdoor electrical systems.
All-Terrain Durability
High-tensile nylon outer sleeve resists abrasion, UV rays, and extreme temps (-55°C to +125°C). Flame-retardant for automotive and industrial use.
Universal Wire Compatibility
Fits 22-10 AWG stranded or solid wires. Color-coded tubes (red/blue/yellow) for quick gauge identification during bulk installations.
Effortless Crimp-and-Seal
Integrated solder melts at 120°C for foolproof repairs. No flux or iron required—just heat with a lighter or heat gun.
Applications
Boating wiring harnesses, automotive trailer lights, RV solar panels, underground irrigation systems, and industrial machinery.
Wholesale Advantage
Factory-direct pricing for 500+ unit orders. Global shipping with certified RoHS/REACH compliance.
