Quadrios 23CA224 Heat Shrink Tubing, Adhesive-Free, Black, 35 mm to 18 mm, 2:1, 1 m

Loose or exposed cable connections need reliable insulation that stays put without adding bulk. The Quadrios 23CA224 heat shrink tubing solves this with a thin-wall polyolefin sleeve that shrinks from 35 mm to 18 mm in diameter, creating a tight, protective seal over splices, terminals, and wire ends. Its adhesive-free design makes it easy to slide over connectors and remove later if rework is needed.

Who is it for

Electricians, automotive technicians, and electronics hobbyists who need a straightforward, non-adhesive shrink tube for bundling, insulating, or strain-relieving cables in dry indoor environments.

Tips

Use a heat gun set to at least 110°C and apply heat evenly around the tubing until it fully conforms to the underlying surface. Avoid overheating to prevent discolouration or damage to nearby components.
