Heat-shrink tubing AWTools AW18317, pack 530 pcs, total weight 190 g

AWTools AW18317 heat-shrink tubing pack includes 530 pieces with a total weight of 190 g, supplied in a plastic storage box with compartments and a size chart label on the inside of the lid for fast identification. Made from polyethylene, the tubing shrinks when heated and contains an inner adhesive that melts at operating temperature to seal and electrically insulate joints. The set is designed for general electrical and electronics repair, cable management, sealing and strain relief of wire harnesses, connectors and terminals.

Advantages

The polyethylene construction provides reliable shrink performance and flexibility while the inner heat-activated adhesive creates a water-resistant seal that improves insulation and corrosion protection. The assortment of tube sizes in the compartmentalized plastic box simplifies selection and storage, and the lightweight pack is suitable for home workshops and professional service use. High resistance to changing weather conditions and moisture ensures stable performance in exposed or humid environments.

Suitable for

• Insulating and protecting bare wires and soldered joints
• Repairing and organizing cable harnesses in appliances and vehicles
• Sealing connectors and terminal ends against moisture and corrosion
• DIY electronics projects and small electrical repairs

Key specifications

• Total weight: 190 g (including storage box)
• Storage: plastic box with compartments and size chart label
• Environmental resistance: moisture and corrosion resistant; suitable for variable weather conditions
• Primary functions: electrical insulation, sealing and strain relief

How to use

Select a tubing size that fits over the connector or joint with slight clearance, slide the tube into position and apply heat evenly using a heat gun, lighter or soldering iron at a safe distance. Heat until the tubing shrinks uniformly and the inner adhesive flows to form a sealed layer; allow the joint to cool undisturbed to complete the bond. For consistent results, maintain an even heating motion to avoid overheating localized areas and ensure the adhesive activates fully.

Usage recommendations

For long-lasting protection, ensure wires are clean and dry before applying tubing. Use a calibrated heat gun where possible and work in a well-ventilated area. Choose a tube diameter that permits the adhesive to contact the substrate after shrinking; for automotive and outdoor applications, prioritize overlapping and fully covering exposed metal to maximize corrosion resistance.
