What Is a Coiled Hose?

A coiled hose is a spiral-formed pneumatic hose commonly used for compressed air connections to pneumatic tools and equipment.

Unlike straight tubing used in fixed piping systems, a coiled hose can extend during use and retract to its original shape when external force is released. This characteristic helps keep the working area organized and reduces hose tangling.

Structural Characteristics of Coiled Hose

Coiled hoses are typically produced through a spiral forming process, allowing the hose to maintain a compact spiral form when not in use while providing sufficient flexibility during operation.

SHPI Coiled Hose Series

Coiled PU Air Hose (Metric)

Provides good flexibility and resilience. Suitable for metric pneumatic systems.

Coiled PU Air Hose (Imperial)

Provides good flexibility and resilience. Suitable for imperial pneumatic systems.

Coiled Reinforced PU Air Hose

A fiber reinforcement layer is embedded within the hose wall to control radial deformation under working pressure. Suitable for higher-pressure pneumatic applications.

Coiled Nylon 12 Air Hose

Manufactured from PA12 (Nylon 12) material, featuring low moisture absorption and stable material behavior. Suitable for pneumatic systems where environmental conditions may vary.

Typical Applications of Coiled Hose

In pneumatic systems, coiled hoses are typically installed between fixed piping and pneumatic tools or movable equipment. Common applications include:

• Pneumatic tool air supply
• Maintenance and service workstations
• Equipment connections requiring operational flexibility
