Butt connector for joining two 12–10 AWG stranded copper wires end to end. Vinyl insulation is the economical choice for dry, protected connections. Rated 600V, -40°C to 105°C.
Use it for: splicing higher-current accessory, heater and pump feeds inside cabins, enclosures and control panels where the connection stays dry.
Getting the right size: match the barrel to the wire gauge. Same vinyl butt connector for other gauges: 22–18 AWG · 16–14 AWG · 8 AWG · 6 AWG · 4 AWG. Same size, different construction: high temp (900°F), non-insulated, nylon, heat shrink (waterproof).
