SVAAR 20PCS 8 Gauge Non-Insulated Butt Connectors 8 AWG Uninsulated Butt Splices Tinned Copper Marine Grade Seamless Barrel Crimp Butt Splice Wire Connectors & 20PCS 3:1 Adhesive Lined Heat Shrinks - size: 8 AWG

About this item

• Package Includes - 20 PCS 8 Gauge (8 AWG) Heavy-Duty Marine-Grade Tinned Copper Non-Insulated Butt Splice Wire Connectors. Rated For 600 Volts. Designed to fit stranded or flexibly stranded copper wire and cable(CLASS B & C Copper Conductors). Can be CRlMPED or SOLDERED - ideal for most applications. Crimped for Mechanical Reliability. Soldered for Strength & Conductivity. One More Thing: We provide 20 PCS 3:1 Dual Wall Adhesive Lined Heat Shrink Tubing for your work (10 PCS Black, 10 PCS Red color). Sealed for Maximum Durability.
• Matte Tinned Copper - SVAAR 8 Gauge(8 AWG) Butt Splice Wire Connectors are crafted from C11000 low-resistivity pure copper (99.9% pure copper). This high-purity copper construction delivers exceptional durability and excellent electrical conductivity. Additionally, a specialized matte tin-plating process enhances conductivity further while providing superior corrosion resistance. 100% tin plated copper resists corrosion from salt and moisture.
• 100% Annealed Copper - All SVAAR Butt Connectors are made of 100% annealed electrolytic-grade copper. The connectors undergo annealing at a specific temperature to enhance material properties and enable better crimping, thereby reducing the risk of breakage during the crimping process.
• SEAMLESS TUBULAR BARREL FOR STRONG CRIMPS - These heavy-duty seamless wire butt splices are engineered for high-amperage applications. Their thick, seamless pure copper barrels ensure maximum conductivity and ultra-strong crimps—they won’t split during crimping, delivering rock-solid connections that prevent wire pull-out. These butt splice connectors guarantee consistently strong, long-lasting, and high-performance electrical connections between wires every time.
• SAFER DESIGN - These Butt Splice Connectors are sized and engineered for use with stranded or flexibly stranded copper wires and cables. These butt splices conform to the UL486 standard, and their thick material ensures ultra-strong crimps while preventing wires from slipping out. Additionally, these non-insulated butt splice connectors feature a wire stop barrier in the center, which guarantees reliable compression performance.
• RECOMMENDED HEAT SHRINK TUBING - For best results with these wire butt splices, we recommend insulating your connections with dual-wall, adhesive-lined heat shrink tubing. When used with the included heat shrink tubing, these butt connectors provide a secure, insulated seal. Adhesive lined design creates a hermetic seal for maximum durability, corrosion resistance and insulation protection. Additionally, the color-coded heat shrink simplifies polarity identification, making installation hassle-free. The wire shrink wraps are all pre-cut into the most common sizes which improve your work efficiency.
• EASY AND SAFE TO USE - These butt splice connectors feature chamfered barrel ends for fast, easy wire insertion from both sides, plus a built-in wire stop to ensure correct positioning. They work well for building custom wire harnesses or repairing existing wiring—easy to install, effortless to maintain, and engineered to deliver greater safety, power, and performance than other wiring methods.
• HOW TO CHOOSE AND USE - SVAAR butt splice connectors give you the flexibility to select from a wide range of wire sizes to match your requirements and applications. When crimping, choose the right butt connectors that fit the wire gauge. Note that some cable manufacturers oversize their cable gauges (this is especially common with audio cables), which may prevent a direct fit. We recommend checking the product dimensions to ensure the connectors fit properly before purchasing.
• WIDE APPLICATIONS - Copper butt connectors are used to mate, connect, or terminate single or multiple wires. Commonly applied in vehicle systems—including automotive and marine applications—they’re also suitable for various electrical setups requiring wire connections. These butt splices terminals are sized for stranded or flexibly stranded copper wire and cable, but are not rated for aluminum conductors.
• BUYER CONFIDENCE - Always match the size and gauge of terminals, cables, and lugs to ensure a proper fit. It’s important to use these connectors with compatible copper cables. We recommend double-checking the dimensions to confirm accuracy before purchasing—this ensures your connections are secure and long-lasting. If you encounter any issues, we stand ready to resolve them for you. Everything you need to get started is included here.
