What Is Reinforced PU Air Hose?

Reinforced Polyurethane (PU) Air Hose is a fiber-reinforced air supply hose used in pneumatic systems. It is designed to control radial deformation under working pressure and maintain structural stability during operation.

Reinforced PU Air Hose Construction and Materials

Three-Layer Structure

• Inner Layer: PU inner tube
• Middle Layer: Fiber reinforcement layer
• Outer Layer: PU outer layer

The reinforcement layer helps control deformation within the specified working pressure range, allowing the hose to maintain structural stability during continuous operation. Working pressure and burst pressure ratings are defined with appropriate safety factors.

Structural Difference Between Reinforced PU Air Hose and Standard PU Tubing

Standard PU tubing is primarily designed for flexibility and dynamic bending applications.

Reinforced PU Air Hose incorporates a fiber reinforcement layer that reduces deformation under pressure. The difference between the two products lies in structural design rather than material type.

Typical Applications of Reinforced PU Air Hose

Reinforced PU Air Hose is commonly installed in pneumatic systems as the air supply connection segment extending from the main piping system to equipment or tools.

These locations typically require both pressure capability and installation flexibility. The hose can be cut to length or supplied as pre-assembled units depending on installation requirements.

Common installation locations include:

• Air supply connection segments at equipment ends
• Air supply hoses for pneumatic tools
• Connection segments requiring removable or flexible installation

Supply Formats of Reinforced PU Air Hose

Reinforced PU Air Hose can be supplied either as bulk hose for cutting or as pre-assembled assemblies. The hose structure and pressure capability are the same; the difference lies in supply format and installation process.

Bulk Hose (UBE Series – Without Fittings)

Hose supplied without fittings, suitable for on-site cutting and assembly according to installation requirements.

Pre-Assembled Hose (UBSA Series)

Hose supplied with fittings assembled before shipment, suitable for direct installation.
