The 1mm Heat Shrink Tube is an ultra-thin, flexible insulation sleeve designed for precision electronics and micro wiring applications. Sold per meter, this tubing is made from high-quality, flame-retardant polyolefin and offers excellent electrical insulation, abrasion resistance, and strain relief. It's ideal for delicate tasks such as covering solder joints on tiny components, insulating jumper wires, or bundling fine wires in compact electronic projects.
To use, cut the desired length, slide it over the wire or joint, and apply heat using a heat gun or lighter. The tube will shrink to approximately half its original inner diameter—from 1mm to about 0.5mm—forming a snug, protective seal. Its small size makes it perfect for use with fine-gauge wires in precision electronics and repair work.
Typical Use Cases:
Insulating very fine wires (28–32 AWG)
Covering micro solder joints on PCBs or modules
Reinforcing fragile jumper wires or single-pin connectors
Electronics prototyping and microcontroller projects (e.g., Arduino, ESP, Raspberry Pi)
Compact cable bundling and labeling
Shrinks from 1mm to ~0.5mm, so ensure it fits over the component before shrinking
Requires careful heat application — excessive heat can damage small components
Not suitable for high-power or high-temperature environments
May become brittle if exposed to UV light or outdoor conditions long-term
