About This

• 3500 Pcs 5-Size Connector Assortment: this waterproof wire connector kit includes 3500 heat shrink butt connectors in 5 widely applied sizes, 1000 blue AWG16-14, 1000 red AWG22-16, 500 white AWG26-24, 500 yellow AWG12-10, 500 black AWG14-12; Color-coded sizing allows quick identification for daily and professional wiring projects
• High-Conductivity Copper Terminals: these heat shrink butt connectors adopt copper crimp barrels with good electrical conductivity and low resistance, which helps reduce voltage loss and heat generation during power transmission; The thickened crimp structure fastens wires tightly for stable electrical connection performance
• IP67 Waterproof Sealing Design: equipped with dual-wall heat shrink tubing and built-in hot melt adhesive, these wire connectors form a 360-degree tight seal after heat activation; They deliver IP67 level protection, effectively blocking moisture, salt spray and corrosive substances from wire connection joints
• Solder-Free Quick Installation: these heat shrink butt connectors support solder-free installation in simple steps, strip the wire, insert into the terminal, crimp and heat with a heat gun; The transparent tubing facilitates crimp inspection, and clear gauge markings improve wiring work efficiency
• Wide Multi-Scenario Application: this heat shrink butt connector kit adapts to various low-voltage electrical projects, including automotive repair, marine electrics, agricultural machinery, control cabinet installation, home appliance repair and electronics wiring for both indoor and outdoor environments
