Heat shrink tubing with 4:1 adhesive; 16mm; L: 1.2m black

A 4:1 heat-shrink tubing with adhesive is a tube that contracts when heated to one-quarter of its initial diameter. It has an internal adhesive lining that melts and flows during heating, creating a watertight seal and a reliable bond. The 4:1 ratio indicates a high shrink capacity.

This sleeve is made of irradiated modified polyolefin or cross-linked polyolefin (PO). It has a dual-wall design, meaning it features an outer heat-shrinkable layer and an inner hot-melt adhesive layer.

The internal diameter of this conduit is 16 mm. After full heat-shrinking, its recovered maximum diameter is 4 mm. The length of the conduit is 1.2 metres.

The ATUM-16/4-0-STK heat-shrink tubing is black.

A double-wall conduit, like this one, offers significant advantages over a single-wall conduit because it combines two functions:

Mechanical protection: The outer wall made of polyolefin provides excellent resistance to abrasion, chemicals, and UV rays. Sealing and insulation: The inner adhesive wall melts and creates a moisture-tight seal, offering superior electrical insulation and environmental protection.

Yes, this double-wall conduit is designed to provide robust protection against UV rays and chemicals, helping to extend the lifespan of electrical connections and components in demanding environments.

Yes, the TE Connectivity ATUM-16/4-0-STK heat-shrink tubing is flame-retardant, providing an additional layer of safety for applications where it is used.

The integrated adhesive lining, or internal adhesive lining, melts and flows when the sleeve is heated. It fills voids and creates a moisture-proof seal, ensuring a reliable bond with materials and providing enhanced environmental protection against moisture, fungi, and weathering.

Yes, thanks to its internal adhesive lining that creates a watertight seal when heated, this sleeve provides excellent protection against moisture, mold, and weathering.

The ATUM-16/4-0-STK heat-shrink tubing has a dielectric strength of 12 kV/mm (or 300 V/mil), ensuring effective electrical insulation for wire splices and terminations.

The sleeve shrinks when exposed to heat. Once the minimum shrink temperature is reached, the sleeve begins to contract. Continuing to apply heat until the full recovery temperature allows the sleeve to conform tightly to the object it covers, and the internal adhesive to melt and flow to form a watertight seal.

The minimum shrink temperature for this sleeve is +80°C. Shrinkage begins at this temperature.

Full retraction of the sleeve, i.e., its maximum withdrawal and optimal adhesive flow, is achieved at a temperature of +110°C (for the ATUM series).

Yes, its high shrink ratio of 4:1 makes it easy to repair most damaged cable sleeves. It provides excellent insulation and protection for the repaired areas.

No, one of the benefits of its high 4:1 shrink ratio is that it makes repair or installation on cables easier without requiring connector removal, simplifying the process.

The internal adhesive of this sleeve ensures a reliable bond with a variety of materials, including plastics, rubbers, and metals, once it has melted and flowed under heat.

With an initial diameter of 16 mm and a maximum recovered diameter of 4 mm, this sleeve is ideal for cables or harnesses with diameters ranging from 4 mm to 16 mm, providing full and watertight coverage after heat-shrink.

Yes, the cable is designed to operate across a wide temperature range, from -55°C to +110°C, making it suitable for various environments, whether cold or hot.

Yes, this heat-shrink tubing complies with the RoHS (Restriction of Hazardous Substances) directive, meaning it meets environmental standards limiting the use of certain hazardous substances.

Yes, due to its protection against moisture, weather, chemicals, and UV rays, as well as its double-wall watertight design, this cable is perfectly suited for marine applications and other demanding outdoor environments.
