PU High-Pressure Tubes: Engineering and Utility Guide

PU High-Pressure Tubes: Engineering and Utility Guide

Understand what to review when choosing PU tubes, including pressure requirements, dimensions, material compatibility and operating conditions.

What Are Polyurethane (PU) High-Pressure Tubes?

Polyurethane (PU) tubes represent an advanced category of pneumatic and hydraulic flexible conduits renowned for combining rubber-like elasticity with the mechanical toughness of rigid plastics. They endure repeated bending, pulsing pressure cycles, and abrasive handling.

  • Extreme flexibility allowing very tight bend radii.
  • High tensile strength with superior burst pressure resistance.
  • High recovery memory preventing permanent kinking.

Pressure Integrity and Burst Strength Factors

Operating pressure, peak surge pressures, and environmental temperatures must be evaluated when selecting PU tubing. Virgin ether or ester based polyurethane ensures consistent wall density and burst tolerance.

  • Recommended working pressure safety factor of 3:1 against burst.
  • High resistance to oils, greases, fuels, and non-corrosive chemicals.
  • Excellent transparency or solid color finishes.

Pneumatic, Fluid Conveyance, and Industrial Applications

From automated robotics and pneumatic control lines to specialized fluid dispensing and automotive utility circuits, PU high-pressure tubes deliver fail-safe fluid and pneumatic transmission.

  • Factory automation pneumatic actuation lines.
  • Lubrication lines and robotic arm conduits.
  • High-pressure water and fluid misting systems.
