Master Appliance Proseal Butt Splice

The Master Appliance Proseal butt splice connector line (also called heat shrink butt connectors or crimp and heat-seal wire connectors) is built for splicing, lengthening and repairing electrical wiring. Each connector is crimped for mechanical reliability and heat-sealed for durability. They suit automotive, marine, home, commercial and industrial electrical work.

Key Features:

• Crimp and heat-seal design gives better wire contact, less voltage drop and better current flow
• Seamless butt connector barrel keeps the barrel from opening, which allows a stronger crimp
• Translucent, adhesive-lined polyolefin heat shrink tubing lets you inspect the splice and helps prevent wire corrosion
• Adhesive flows uniformly and does not overflow onto the terminal, so it does not interfere with contact
• Tubing keeps its length when heated, which improves insulation, wire support and strain relief
• Watertight seal resists moisture, contaminants, abrasion, wire pullout and current leakage
• Color-coded insulation with a wire gauge imprint makes it easy to pick the right connector for the job

How to use: Strip the wires and insert them into the connector. Crimp it, then apply heat until the adhesive flows and the tubing shrinks around the splice. Let it cool.

Proseal connectors are a dependable choice for professionals and DIYers who want durable, sealed wire splices.
