Quadrios 26CA777 Heat Shrink Tubing Without Adhesive Black 20 mm to 10 mm 2:1 5 m

Electricians and maintenance technicians rely on this heat shrink tubing to insulate and protect wire splices, cable bundles, and connectors in control panels and automotive wiring. The black polyolefin sleeve slides over a 20 mm diameter component and, when heated, shrinks to a snug 10 mm fit, providing a durable, professional finish.
