Butt Connecter
A butt connector joins two wires end to end in a neat, insulated sleeve, with no twisting or tape. Auto electricians, appliance and harness makers, panel builders and dealers use this butt splice connector range for repairs and extensions. Each insulated butt connector is colour-coded by wire size and crimps from both ends.

Insulated Butt Splice Connector for Wire Joints
A crimped wire joint connector is stronger and more reliable than a twisted joint wrapped in tape, and it does not work loose with vibration. Strip both wires to the same length, push them in until they meet in the middle, and crimp each side. Pick the colour that matches the wire size and see the product page for size bands. Keep the joint away from sharp edges and heat, and support the run with a tie on either side. Splices like this are standard in auto and appliance repair, where wires often need a little more length.
Crimp each end with a butt connector crimping tool so the sleeve stays intact, and strip leads with a wire stripper. Ashwin Tools ships orders direct with 10-day returns, and auto and electrical dealers can join our dealership programme.
