Nylon Fully Insulated Butt Splices

Nylon Fully Insulated Butt Splices join two wires end-to-end with a connection that is both mechanically strong and fully protected. The electrolytic copper barrel is tin-plated against corrosion, and the tough nylon insulation covers the splice completely - no tape, no sleeving, no exposed metal.

The insulation doubles as an insertion guide: the wire slides smoothly into the funnel entry, and the crimp barrel holds it with reliable strength. Red, blue and yellow codes match the standard wire-size pattern, making selection straightforward on the bench or the van.

Bulk-packed at 1000 pieces per bag across 5 sizes, these butt splice connectors are the dependable choice for professional electrical wiring, industrial assembly and repair work - and they pair naturally with heat-shrink sleeving where an extra moisture barrier is wanted.
