QUADRIOS 1908CA072 Heat Shrink Tubing, 45 mm, 2:1, Black, Non-Adhesive

Exposed electrical connections and cable splices are vulnerable to moisture, abrasion, and short circuits. This heat shrink tubing provides a tight, insulating seal that protects wiring and keeps installations neat.

Who is it for

Electricians, automotive technicians, and DIY enthusiasts who need reliable insulation and strain relief for cables, connectors, and wire bundles.

Main features

• Supplied inner diameter of 45 mm shrinks to 22.5 mm with a 2:1 ratio for a snug fit.
• Cross-linked polyolefin material is flexible, flame-retardant, and resistant to UV and chemicals.
• Non-adhesive lining allows easy repositioning before final heat application.
• Wide operating temperature range from -55°C to +125°C.
• Dielectric strength of 20 kV/mm provides excellent electrical insulation.

Tips

Use a heat gun with a deflector nozzle for even shrinking. Start from the centre and work outward to avoid air pockets. Allow the tubing to cool completely before moving the cable.
