Heat Shrinkable Tubing 20mm - 1 Meter

Heat Shrinkable Tubing 20mm - 1 Meter

This 20mm diameter heat shrinkable tubing provides a professional and reliable solution for insulating and protecting wires, cables, and connectors. Supplied as a convenient 1-meter length, it shrinks tightly around components when heated, creating a durable, abrasion-resistant layer that guards against moisture, dust, and mechanical damage.

Key Features

The tubing has a 20mm internal diameter before shrinking and contracts to approximately half its original size when heat is applied, ensuring a snug and secure fit around joints and splices. It is flexible, flame-retardant, and resistant to common solvents, making it suitable for both hobbyist electronics projects and professional wiring installations.

Specifications

Diameter: 20mm pre-shrink; Length: 1 meter; Shrink ratio: approximately 2:1; Material: durable polyolefin-based insulation sleeve designed for long-term reliability in typical electronic operating environments.

Applications

Ideal for insulating solder joints and wire splices, bundling and organizing cable harnesses, reinforcing connector strain relief points, color-coding wiring, and adding a clean, professional finish to DIY electronics, robotics, automotive, and repair projects.

How to Use

Simply cut the tubing to the desired length, slide it over the wire or connection, and apply heat evenly using a heat gun, hot air rework station, or lighter. The tubing shrinks uniformly and conforms tightly to the underlying surface, forming a permanent protective seal.
