The braided heat shrink tubing combines the properties of traditional heat shrink tubing and a durable textile braid. This piece has an internal diameter of 20 mm and a length of 20 m, making it suitable for very thick power cables, wide bundles of wires, and thick conduits. When heated with hot air, the braid shrinks at a ratio of 2:1 and tightly wraps around the protected wiring. The braided surface is flexible, highly abrasion-resistant, and according to the manufacturer, helps reduce cable noise. The twenty-metre packaging is ideal for workshops, service centres, and larger projects where many very thick cables and wide bundles need protection.
Shrinkage begins at approximately 80 °C and complete shrinkage is achieved around 120 °C. A hot air gun is sufficient for heating, and the manufacturer also mentions the possibility of using a lighter. Once cooled, the tubing forms a continuous textile layer that protects the insulation of the wires from mechanical damage, abrasion, and heat. The material is self-extinguishing with a flammability rating of VW-1 and withstands operating temperatures from −40 to +150 °C, making it suitable for wiring in cars or electrical appliances that heat up during operation. The tubing can be used to protect joints, terminate cables, extend wires, or bundle several thin cables into one neat bundle.

When selecting the size, follow the diameter of the cable. The manufacturer recommends choosing tubing approximately 3 mm larger than the diameter of the protected wiring. For flat cables or bundles with a rectangular cross-section, the required diameter is calculated by adding the width and height, multiplying by two, dividing by 3.14, and adding 3 mm. The tubing is supplied in one piece, so you can cut it to the exact lengths you need before shrinking. Slide it onto the cable before connecting the connectors, then move it to the desired position and evenly heat it along its entire length.
The braided heat shrink tubing with a diameter of 20 mm is a practical accessory for anyone repairing, modifying, or installing electrical wiring. The length of 20 m is suitable for workshops, service centres, and larger projects where you repeatedly modify heavy cabling and need to have tubing readily available. The textile surface protects the wires from abrasion, the heat from the hot air gun quickly shrinks it, resulting in neatly and securely arranged cabling. Thanks to its self-extinguishing properties and resistance up to +150 °C, it can be used in electronics, automation, electrical appliances, and cars.
