Nylon Insulated Butt Splice Wire Connectors Copper Crimp Terminals Electrical

【NO-CRACK NYLON SLEEVE】Engineered with premium, semi-transparent nylon insulation that provides extreme toughness. Unlike cheap PVC connectors, these nylon butt splices will not crack or split during crimping, ensuring a fully insulated, professional finish every time.

【PREMIUM TINNED COPPER CORE】Features a pure red copper inner tube coated with a premium tin layer. This delivers maximum electrical conductivity, prevents wire slippage under tension, and offers superior resistance to oxidation, corrosion, and rust.

【INTERMEDIATE BARRIER DESIGN】The internal metal tube features a built-in central wire stop barrier. This intelligent design ensures that wires inserted from both sides meet perfectly in the middle, preventing over-insertion and guaranteeing a perfectly balanced joint.

【FLAME-RETARDANT & SAFE】The robust nylon housing is high-temperature resistant and flame-retardant, significantly reducing the risk of electrical fires. Ideal for high-vibration and demanding environments like marine, automotive, and heavy machinery cabling.

【VERSATILE MULTIPACK OPTIONS】Available in single-spec packs (50/100PCS). Covering wire ranges from 0.2mm² to 6.0mm² (22-10 AWG), it’s the ultimate wiring solution for car DIYers, professional electricians, and home repairs.
