Narva Dual Wall Heat Shrink Red 39mm

The Narva Dual Wall Heat Shrink Red 39mm is a versatile and high-quality heat shrink tubing designed for a wide range of electrical and cable protection applications. It features dual-wall construction, providing enhanced protection against moisture, abrasion, and environmental factors.

1. Size:

   • Outer Diameter (OD): 39mm.
   • This makes it suitable for larger cables, connectors, or components that require a wider protective cover.

2. Dual-Wall Construction:

   • Outer Wall: The outer layer of the tubing is typically made from a durable, heat-resistant polymer that provides resistance to abrasion, UV light, and chemicals.
   • Inner Wall: The inner layer is a hot-melt adhesive that melts and flows when heated, creating a seal around the cable or connector. This adhesive enhances the tubing's ability to waterproof and insulate the wires it covers, ensuring a stronger bond and better protection from moisture and environmental elements.

3. Heat Shrink Technology:

   • When exposed to heat, the tubing shrinks to conform tightly around the cable or connector, providing a secure, professional-looking, and permanent fit.
   • Typically, a heat gun or other heat source is used to apply the required heat for the tubing to shrink.

4. Material:

   • Made from high-quality, flexible materials that provide both insulation and protection from harsh environmental conditions.

5. Color:

   • Red: Often used to differentiate or color-code cables for easier identification or to match the system’s design specifications. The color also serves to signify specific functions in electrical systems, such as positive or live wires in DC circuits.

6. Temperature Range:

   • Narva heat shrink tubing typically operates within a broad temperature range, suitable for use in both high and low-temperature environments. This helps maintain its protective properties in diverse conditions.

Benefits:

• Moisture and Environmental Protection: The dual-wall design with the adhesive inner layer provides superior protection against moisture, dust, and contaminants, making it ideal for use in outdoor or wet environments.
• Durability: The tough outer layer offers high resistance to wear, tear, abrasion, and chemicals, ensuring longevity and reliability in demanding conditions.
• Enhanced Insulation: The heat-shrink process, combined with the adhesive inner layer, offers superior electrical insulation, protecting wires from short circuits and other electrical failures.
• Versatility: It can be used for a variety of applications, including automotive, industrial, marine, and household electrical projects.

Applications:

• Automotive: Ideal for protecting wires and connectors in automotive electrical systems, ensuring protection from moisture, chemicals, and vibrations.
• Industrial: Used to safeguard cables in industrial environments where exposure to abrasion and harsh conditions is common.
• Marine: Perfect for use in marine applications where exposure to saltwater and UV light can degrade unprotected wiring.
• DIY and Electrical Projects: Suitable for home, hobby, or custom electrical installations, providing a professional finish and reliable protection for all types of wiring.
