About This

High-Performance Tinned Copper Core in Heat Shrink Butt Connectors : 99.9% pure tinned copper in our butt connectors ensures optimal conductivity with minimal voltage drop and heat generation. The seamless design of these wire connectors guarantees secure connections, preventing slippage and shorts - perfect for automotive, marine and electrical applications.
No-Solder, Tool-Friendly Installation for Butt Connectors Heat Shrink : Simply strip wires, insert into the butt connectors, crimp with pliers, and apply heat (using a heat gun or lighter). The transparent sleeve allows for easy inspection, while color-coded sizes simplify identification of these heat shrink connectors. No welding required!
Waterproof & Flame-Retardant Wire Connectors Heat Shrink : Marine-grade polyolefin tubing with a 3:1 shrink ratio and adhesive lining creates a 360° waterproof seal. Dual-wall insulation resists flames and environmental damage, making these heat shrink connectors safe for underground, marine, or outdoor use.
Durable Against Physical Damage : Reinforced tubing on these heat shrink butt connectors withstands rodent bites, abrasion, and mechanical stress. The thick tinned copper core and seamless barrel design ensure long-lasting, vibration-resistant wire connectors—even in harsh conditions (-55°C to 125°C).
Versatile Heat Shrink Butt Connectors Kit for Diverse Projects : Includes 500pcs heat shrink butt connectors kit for automotive, boat, home, and industrial wiring. Reliable performance with a full shrink temperature of 130°C and superior conductivity for secure, low-resistance wire connectors heat shrink every time.
