About This

• ALL YOU NEED IN ONE PACKAGE - Non-Insulated Butt Splice Wire Connectors total 460 pieces, made of pure copper and rated 600 volts. Fits solid and stranded copper wires, available for crimping and soldering installation. Crimping ensures firm mechanical stability, soldering boosts durability and conductivity. Bare pure copper butt splices are heavy-duty, pure copper, electrical connectors designed for high amperage applications. This wire splice connector set offers diversified sizes and ample quantity, covering 26 AWG to 6 AWG: 6 AWG×4PCS, 8 AWG×8PCS, 12-10 AWG×18PCS, 14-12 AWG×40PCS, 16-14 AWG×60PCS, 22-16 AWG×100PCS, 22-18 AWG×110PCS, 26-22 AWG×120PCS, meets various wiring demands.
• SEAMLESS TUBULAR BARREL - Non-Insulated Butt Splice Connectors are made of 99.9% high-conductivity ETP pure copper with seamless structure. One-piece design ensures better conductivity and crimp performance than traditional seamed and brazed connectors. Heavy-duty seamless wire splices perfectly built for high-amperage use. 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.
• PURE COPPER MATERIAL: Non-Insulated Butt Splice Connectors in 26-6 AWG gauge from SVAAR are all made of seamless high-conductivity copper tubing. Crafted from bare pure copper, they deliver superior conductivity to support maximum current flow, ensure efficient power transmission and bring stable optimal performance to all your electrical wiring connections.
• 100% ANNEALED COPPER - Non-Insulated Butt Splice Connectors from SVAAR are crafted from 100% annealed electrolytic-grade copper. These connectors are treated with professional high-temperature annealing to optimize material toughness, allowing for easier and tighter crimping and effectively preventing cracking or damage during crimp operation.
• CHAMFERED BARREL & WIRE STOP STRUCTURE - SVAAR Non-Insulated Butt Splice Connectors adopt deburred and chamfered barrel design for safe wiring installation, effectively avoiding wire fraying during assembly. Smooth chamfered ends allow quick and easy wire insertion from both sides, while the built-in wire stop ensures accurate wire positioning. Perfect for custom wire harness making and wiring repair work, they are simple to install and easy to maintain, offering higher safety, stable power output and better overall performance.
• SAFER DESIGN - Non-Insulated Butt Splice Connectors from SVAAR are precisely sized and engineered for solid or stranded copper wires and cables. They comply with UL486 standard, and thick solid construction enables firm crimps to effectively prevent wire slippage. They meet UL486 standards. Thick solid structure delivers firmer crimps to stop wire slipping. Boasts stronger crimp, superior tensile strength and better wire contact for lower voltage drop, with no cracking risk compared to butted and brazed connectors.
• HOW TO CHOOSE AND USE - SVAAR Non-Insulated butt splice connectors kit 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. Besides, choose the proper crimping pliers. Improper pliers cause loose or damaged crimps, affecting fitting stability.
• RECOMMEND HEAT SHRINK TUBING - Non Insulated Butt Splice wire connectors ensure connections get the strongest, longest lasting, and highest performing electrical connections between every wire, every time. For best results we recommend insulating your connections with dual wall, adhesive lined heat shrink tubing.

• 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.
