What Is Reinforced PU Air Hose?

Reinforced PU Air Hose is a pneumatic air supply hose with a fiber-reinforced structure and is classified as a structurally reinforced product. Under working pressure, the reinforcement layer controls radial deformation to maintain the structural stability of the hose.

Reinforced PU Air Hose Construction and Materials

Reinforced PU Air Hose adopts a three-layer construction with a fiber reinforcement layer positioned between the inner and outer PU layers.

Three-Layer Structure

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

The reinforcement layer controls 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 using 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 their structural design rather than their 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 piping system to equipment or tools. These locations typically require both pressure capability and installation flexibility, and the hose may be cut to length or supplied as a pre-assembled unit according to application 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 a pre-assembled hose. The hose construction and pressure design are the same; the difference lies only in the supply format and installation process.

Bulk Hose (UBE Series – Without Fittings)

Supplied as hose without fittings, suitable for on-site cutting and assembly according to installation requirements.

Pre-Assembled Hose (UBSA Series)

Supplied with fittings assembled before shipment, suitable for direct installation.
