500 Pcs Heat Shrink Butt Connectors, 22-16 AWG Marine Grade Waterproof Electrical Wire Connectors, Insulated Crimp Terminals for Automotive, Boat, Industrial Applications

500 Pcs Heat Shrink Butt Connectors, 22-16 AWG Marine Grade Waterproof Electrical Wire Connectors, Insulated Crimp Terminals for Automotive, Boat, Industrial Applications

• 【500 Pcs Set】These 500 Pcs Heat Shrink Butt Connectors, 22-16 AWG Wire Crimp Terminals, provide sufficient quantity for large wiring projects (e.g., automotive repairs, marine electrical work) or regular replacements. The count meets needs for professional use (workshops, factories) or home DIY, ensuring no shortage of connectors during multi-point wiring tasks
• 【Marine Grade】These Marine Grade Heat Shrink Connectors, Waterproof Electrical Terminals, use polyolefin heat shrink tubing with hot melt adhesive inside. They resist water, corrosion, and vibration, suitable for harsh environments like boats (humid) or cars (temperature changes). The insulation protects wires from mechanical damage, extending the life of electrical connections
• 【Tinned Copper Core】These 22-16 AWG Heat Shrink Connectors have high-purity tinned copper cores that ensure good electrical conductivity—reducing voltage drop and preventing wiring failures. The copper core crimps tightly to wires, keeping connections stable so wires won’t slip out even under frequent vibration (e.g., in automotive engines)
• 【3:1 Shrink Ratio】These 3:1 Ratio Heat Shrink Butt Connectors shrink to 1/3 of their original size when heated (80℃ start, 130℃ full shrink). The tight shrinkage, paired with hot melt adhesive, creates a sealed, waterproof connection. They work with 22-16 AWG wires, and the size marking on the tubing makes it easy to select the right connector
• 【Wide Use】Ideal as Automotive Heat Shrink Connectors, Industrial Electrical Terminals, they apply to boats, cars, industrial equipment, and home wiring. Operating temperature ranges from -55℃ to 125℃, adapting to cold winters or hot engine bays. The pink color helps distinguish them from other connector types, simplifying inventory management
