Quadrios 26CA781 Heat Shrink Tubing 40 mm Black 5 m 2:1

Exposed wires and cable splices are vulnerable to abrasion, moisture, and short circuits. This heat shrink tubing provides a tight, durable insulation sleeve that protects electrical connections and keeps wire bundles organized.

Who is it for

Electricians, automotive technicians, and DIY enthusiasts who need reliable insulation for wire splices, cable ends, and harnesses. It is especially useful for larger cables and connectors requiring a 40 mm initial diameter.
