The AIRflex-KUW-PVC-AS AD36 from Flexa is a helically wound plastic protective hose, specifically designed for use in industrial and technical applications. It consists of a soft PVC sheath enclosing a spring steel wire helix, providing high flexibility and mechanical stability. The hose is available in a package with a length of 10 meters and is finished in gray. It is used for the protection and guidance of cables, lines, and hoses in areas such as machine building, plant engineering, vehicle construction, shipbuilding, automation, and electrical installations. Due to its construction, it is also suitable for use in guide chains and can be used as a suction hose.

Applications
This protective hose is designed for applications in industrial environments where high mobility and mechanical load capacity are required. It is frequently used in automation technology, where cables and lines must be moved or guided, for example in robotic systems, conveyor systems, or on movable machine parts. Its use in vehicle and shipbuilding enables safe and flexible cable routing under harsh conditions. The air- and fluid-tight construction also makes it suitable for applications requiring sealing against environmental media.

Functions and Equipment in Detail
The AIRflex-KUW-PVC-AS AD36 is characterized by its highly flexible structure, allowing the hose to be used in tight curves and under frequent movement without material fatigue or breakage. It is stretchable and compressible, making it particularly suitable for applications with dynamic length changes. The soft PVC sheath offers high protection against external influences, including mechanical stress, and is largely resistant to acids and oils. Additionally, the hose is silicone- and cadmium-free, making it suitable for sensitive applications. An internal corrosion protection ensures the spring steel wire helix is protected against oxidation, extending the hose’s service life.

Technology Explained Simply
The protective hose consists of an internal spring steel wire helix covered with a soft PVC plastic sheath. This construction ensures high mechanical strength while maintaining flexibility. The helical structure allows the hose to stretch and compress without structural damage. The PVC sheath protects the internal metal structure from external influences and provides a tight covering. The temperature resistance of -25°C to +90°C (with a possible short-term increase up to +100°C) makes the hose suitable for a wide range of environments, even under changing climatic conditions.

Compatibility and Accessories
The AIRflex-KUW-PVC-AS AD36 can be combined with various cable glands and end caps to ensure secure attachment to devices or installations. Compatible accessories include, for example, plastic cable glands made of polypropylene (e.g. LKI-P AD36-PG29, LKI-M AD36-M40), metal cable glands made of nickel-plated brass (e.g. US-M AD36-M32, USW-M AD36-M40), and end caps made of polypropylene (e.g. EK AD36, EEK AD36). These components enable flexible and secure mounting on various devices and installations. Hose clamps such as the SKM AD34,5-36 made of galvanized steel/rubber can also be used to fix the hose at specific points.

Installation and Mounting
The installation of the protective hose typically involves attaching cable glands or end caps to the ends of the hose to secure it to devices, machines, or guide systems. The stretchable and compressible structure allows easy adaptation to different lengths and movement sequences. The use of clamps or cable glands ensures secure fastening, even under dynamic conditions. Installation requires no special tools, although the selection of the appropriate cable gland or end cap depending on the connection type and environment is crucial.

Operational Advantages
The AIRflex-KUW-PVC-AS AD36 offers high reliability in operation due to its mechanical stability and flexibility. The air- and fluid-tight construction protects the cables and lines inside from environmental media. Resistance to acids and oils makes it suitable for demanding industrial environments. The silicone- and cadmium-free composition reduces the risk of contamination, which is advantageous in sensitive applications. The internal corrosion protection extends the hose’s service life and reduces maintenance requirements. Certifications according to EN IEC 61386-25, UK-CA, REACH, and RoHS, as well as compliance with UL_LLC, confirm the safety and quality of the product.
