Where to use it
Use these connectors to join two 0.5 - 1.5 mm² cables end to end with a sealed, insulated joint. Crimp each side, then heat the sleeve to shrink it around the cable, helping keep out moisture and stop the joint working loose from vibration.
Pair with
Crimp with an insulated terminal ratchet crimper such as the Alvolta Insulated Ratchet Crimping Tool, then shrink the sleeve with a heat gun.
Ideal for
Caravans and RVs
4WDs and camper trailers
Marine wiring
Off-grid and 12 V systems
Automotive repairs
Heat shrink butt splice connectors are used to join or repair electrical wires securely while providing insulation and protection against moisture, dust, and vibration. They’re ideal for automotive, marine, solar, and off-grid wiring applications where durability and weather resistance are essential.
Simply strip the ends of your wires, insert them into each side of the connector, and crimp them firmly with a quality crimping tool. Then apply heat using a heat gun until the tubing shrinks tightly around the wire and adhesive seals the connection for a waterproof, long-lasting bond.
Yes. When properly crimped and heated, the internal adhesive lining melts to form a watertight seal, protecting your electrical connection from corrosion and environmental damage. This makes them perfect for outdoor, marine, and 12V vehicle applications.
