Tubo termorretrátil CellPack 127421, 100 cm de tubo, embalagem individual

CellPack 127421 is a heat-shrink tubing supplied as a single 100 cm tube designed for electrical insulation, cable repair and protection. The tube provides mechanical protection and dielectric isolation for wires, solder joints and connector terminations, and is suitable for hobby, maintenance and professional wiring tasks that require a reliable heat-shrink sleeving solution.

Advantages

The heat-shrink material conforms tightly to irregular shapes when heated, creating a durable protective layer that resists abrasion and moisture. Supplied as a single 100 cm tube, the product is simple to store and cut to the required length for one-off repairs or small projects. It offers consistent shrink performance and good dielectric properties for common low-voltage electrical and electronics applications.

Key specifications

How to use

Cut the tube to the desired length, slide it over the wire, splice or connector area, and apply uniform heat until the tubing contracts and conforms to the underlying shape. Use a heat gun or controlled flame source at a safe distance to avoid overheating nearby components; heat until the tubing is snug and free of voids. Allow the component to cool before handling. For secure strain relief, position the tubing so it overlaps both the cable insulation and the connector or joint.

Recommendations

For predictable results, select a tube diameter that provides adequate overlap before shrinking and heat evenly with a temperature-controlled heat gun. Store the tube in a dry place away from direct sunlight; sections in a spool may be tied together, so inspect the tube and cut off any tied portions before use. Other lengths are available on request if a different tube length is required.
