Waterproof Heat Shrink Solder Connector Sleeve for Cable Insulation Wire Connector (18-22 AWG)

The Waterproof Heat Shrink Solder Connector Sleeve is a solder-and-seal wire connector designed for quick, reliable, and weatherproof electrical connections without the need for crimping tools. Ideal for 18–22 AWG wire sizes, it simplifies the wire splicing process using a heat-activated solder ring and dual-wall heat shrink tubing with adhesive lining. This type of connector is commonly used in automotive, marine, drone, robotics, and outdoor wiring projects where moisture resistance and durability are critical.

Key Features:
• Combines soldering, sealing, and insulation in one step
• Waterproof and corrosion-resistant connection
• Heat-shrink tubing with inner adhesive lining for strong bond
• Low-temperature solder ring melts and flows around wires during heating
• Transparent sleeve for visual inspection of splice
