3:1 Adhesive-Lined Heat-Shrink Tubing Ø22–6 mm Black – 1 m

The 3:1 Adhesive-Lined Heat-Shrink Tubing Ø22–6 mm is designed to protect, insulate and reinforce cables, connectors, electrical joints and other components.

When heated, the tubing shrinks around the component while its internal adhesive melts and fills small gaps. This dual-wall construction provides more effective protection against moisture, dust, vibration, abrasion and mechanical stress than conventional non-adhesive heat-shrink tubing.

Its 22 mm initial diameter allows it to pass over larger connectors and components. After full recovery, it can reach approximately 6 mm in diameter, creating a firm fit around the cable or connection.

Supplied in a 1-metre length, it can be cut to suit each application.

Application instructions

1. Cut the tubing to the required length.
2. Slide it onto the cable before completing the connection.
3. Position it over the area requiring protection.
4. Apply heat evenly using a suitable heat gun.
5. Continue heating until the tubing has fully shrunk and the adhesive seals the ends.
6. Allow it to cool completely before handling the connection.

Important note

Confirm that the 22 mm initial diameter will pass over the widest part of the component and that the 6 mm recovered diameter is small enough to grip the cable firmly.

Use a suitable heat gun and avoid direct flame, overheating or applying heat to one point for an extended period.
