Key features

• •[EXCELLENT QUALITY] - Our heat shrink butt connectors are made with high-quality tinned copper, ensuring excellent conductivity and durability. The copper core is easy to flatten and grip the wire, providing a strong and reliable connection.
• •[COMPLIANT WITH RELEVANT STANDARDS] - These heat shrink waterproof wire connectors are compliant with ROHS, ISO 9001:2008, SGS, and CE standards. Package includes 200pcs of heat shrink butt connectors in three different sizes: 90pcs red, 90pcs blue, and 20pcs yellow.
• •[WATERPROOF] - With a waterproof insulated design, our connectors feature a polyolefin tubing on the outside and a hot-melt glue inner layer. This provides excellent water resistance when heated, ensuring long-lasting performance even in challenging environments.
• •[PERFECT FOR REPAIRS] - Designed for repair technicians, our connectors are perfect for electrical wiring repairs. The seamless copper barrel design offers high tensile strength and resistance to mechanical damage. The translucent heat shrink tubing eliminates the issue of the barrel opening, while the high elasticity ensures steady performance.
• •[EASY TO USE] - Simply remove the wire insulator, choose the desired terminal color, insert the wire into the terminal, and crimp using a crimping tool. Repeat the process for the second wire, and then use an air gun to apply heat on the heat shrink connectors for a secure and professional connection.
