Heat shrink adhesive tube MACLEAN MCTV-541 12.7 mm × 5 m

Heat shrink adhesive tube MACLEAN MCTV-541 12.7 mm × 5 m is a self-sealing heat shrink sleeve designed to provide mechanical protection, electrical insulation and moisture sealing for cable joints, terminals and repairs. Before shrinking the tube has a 12.7 mm diameter and the roll contains 5 m of continuous tubing. The inner adhesive layer melts during heat application to form a watertight bond around conductors and connectors while the outer polymer jacket provides abrasion resistance and strain relief.

Advantages

The MACLEAN heat shrink adhesive tube combines a high-adhesion inner sealant with a durable outer polymer to deliver reliable protection for electrical connections. Its continuous 5 m length allows cutting to required sizes for both small repairs and longer runs. The tube shrinks uniformly when heated to create a tight fit, improving mechanical stability and reducing the risk of moisture ingress. The product is suitable for both household wiring tasks and light industrial applications where insulated, sealed joints are required.

Suitable for

• Insulating and sealing cable joints and splices
• Repairing damaged insulation on wires and cables
• Protecting terminals and connector assemblies from corrosion and moisture
• Providing strain relief on cable entries and transitions
• General wiring and maintenance in household and light industrial environments

Key specifications

• Nominal diameter before shrinking: 12.7 mm
• Length: 5 m (continuous tubing)
• Construction: heat-shrinkable polymer outer jacket with inner adhesive/sealant layer
• Function: mechanical protection, electrical insulation, moisture sealing, strain relief
• Application temperature: suitable for heat activation by standard heat gun or controlled flame (follow safe heating procedures)

How to use

Select an appropriate length of tubing and slide it over the cable or joint before making electrical connections where relevant. Apply heat evenly along the tube with a heat gun or other controlled heat source until the tube shrinks uniformly and the inner adhesive flows to form a continuous seal. Allow the sleeve to cool so the adhesive sets and the outer jacket solidifies. Trim excess material if needed and inspect the sealed area to ensure full adhesion and coverage.

Usage recommendations

Use a regulated heat gun at moderate distance and move it continuously to avoid overheating. Ensure surfaces are clean, dry and free of contaminants before applying the tube. For critical or high-voltage installations, follow applicable electrical codes and, if necessary, use additional mechanical protection or professional installation services.
