QUADRIOS 1908CA067 Heat Shrink Tubing, 2:1, 25 mm, Black, Non-Adhesive

Loose or exposed wires create short-circuit risks and untidy installations. This QUADRIOS heat shrink tubing solves that by providing a tight, protective sleeve for electrical insulation, wire bundling, and strain relief. With a 25 mm supplied diameter and a 2:1 shrink ratio, it recovers to 12.5 mm when heated, conforming closely to the underlying components.

Who is it for

Electricians, automotive technicians, and electronics hobbyists who need a reliable, non-adhesive shrink tube for general-purpose insulation and mechanical protection.
