Festo – Polyurethane Tubing PUN-H-12X2-BL | Flexible Pneumatic Tube – 12mm OD, 2mm Wall, Blue

The Festo PUN-H-12X2-BL Polyurethane Tubing is a high-quality pneumatic hose designed for flexible, durable, and reliable fluid and air conveyance in industrial automation systems. Made with hydrolysis-resistant polyurethane, this tubing is ideal for dynamic applications where flexibility, kink resistance, and long service life are critical.

Festo’s PUN-H series is known for its versatility in pneumatic circuits, robotics, automotive manufacturing, packaging machinery, and other demanding environments. The PUN-H-12X2-BL model features an outer diameter of 12 mm and a wall thickness of 2 mm, offering a 10 mm internal diameter, which is optimal for medium to high air flow systems.

Engineered for Durability and Performance

The tubing is constructed from premium-quality polyurethane (PU) with hydrolysis resistance properties. This makes it especially suitable for use in humid or damp environments, such as in food processing lines, washdown areas, or outdoor applications. The PUN-H material remains soft and flexible even at low temperatures, ensuring minimal stress on fittings and easy routing in tight spaces.

Unlike traditional PVC or rubber hoses, Festo’s polyurethane tubing resists cracking, swelling, and chemical degradation over time, providing reliable long-term performance in both static and dynamic pneumatic systems.

Flexible and Kink-Resistant Design

The PUN-H-12X2-BL is designed to be highly flexible, with a small bending radius that allows it to be routed easily around corners and through complex machinery. Its kink-resistant structure helps maintain consistent airflow without pressure drops, even when bent during installation or in moving machinery.

This makes it ideal for applications involving robotic arms, pneumatic cylinders, pick-and-place units, and any system requiring frequent movement or tight routing paths.

Pressure and Temperature Resistance

This tubing is rated for:

Operating Pressure: Up to 10 bar (depending on temperature and application)
Temperature Range: -35°C to +60°C

This makes it suitable for most standard pneumatic setups and safe for use in both refrigerated areas and hot industrial environments. The tubing maintains its elasticity and dimensional stability across this wide range.

Chemical and Environmental Resistance

The PUN-H series offers good resistance to hydrolysis, microbes, and various cleaning agents. This makes it suitable for:

Food and beverage environments (dry air supply only)
Laboratories
Industrial machinery in humid zones
Outdoor pneumatic systems with occasional water exposure

Note: The tubing is not suitable for direct contact with food-grade fluids unless otherwise certified.

Color-Coded for Easy Identification

The “BL” at the end of the product code indicates Blue color, which provides visual distinction for organizing different air lines or media in complex systems. Festo’s PUN-H tubing is also available in multiple colors for multi-line setups and maintenance-friendly installations.
