Construction and Material Profile
The Festo PUN-H-10X1,5-SW-25 (part number 8204443) is a black polyurethane tubing with an outside diameter of 10 mm and an inside diameter of 7 mm. The material is a TPE-U (PU) with an ether-based formulation, which gives it flexibility and resistance to hydrolysis. This makes it a practical choice for applications where the tubing is exposed to moisture or humid environments. The tubing has a Shore hardness of D 52 +/-3 and a weight of 0.0465 kg/m, which are useful figures when calculating load and routing requirements.
The tubing is marked as suitable for energy chains, meaning it is designed to withstand the repeated flexing and movement common in automated machinery. Its minimum bending radius is 28 mm, while the bending radius relevant for flow rate is 52 mm. These values help engineers plan layouts that avoid kinking or restricting air flow.
Operating Parameters and Medium Compatibility
The PUN-H-10X1,5-SW-25 is rated for use with compressed air per ISO 8573-1:2010 [7:-:-] and with water (liquid, ice-free). For compressed air, the operating pressure is temperature-dependent, ranging from -13.775 psi to 145 psi. For the entire temperature range, the pressure is limited to 87 psi. When using water, the maximum pressure is 0.3 MPa at 0–60 °C, as indicated in the manufacturer's diagram. These pressure ratings are essential for sizing the tubing correctly in pneumatic circuits.
The ambient temperature range is -35°C to 60°C, which covers most industrial environments. The tubing is also certified by the German Technical Control Board (TÜV) under certificate number B 013277 0506 00, providing an additional layer of quality assurance.
Compliance and Suitability for Specialized Environments
This tubing is designed with several compliance features that make it versatile. It is food-grade, with supplementary material information available for use in the food industry. It also meets LABS (PWIS) conformity per VDMA24364-B2-L, which is important for paint and coating applications where silicone-free materials are required. The material fire test rating is UL94 HB, indicating a horizontal burn test classification.
For cleanroom applications, the tubing is a statically installed element, so no meaningful evaluation is possible according to ISO 14644-1. It is also RoHS-compliant, ensuring it meets environmental standards. Additionally, the tubing is suitable for the production of Li-ion batteries, with the caveat that metals with more than 1% by mass of copper, zinc, or nickel are excluded from use, except for nickel in steel, chemically nickel-plated surfaces, circuit boards, cables, electrical plug connectors, and coils.
Installation and Integration Benefits
The PUN-H-10X1,5-SW-25 is designed for use with plug connections for a 10 mm outside diameter. This allows for quick and secure connections using standard push-in fittings. The tubing's flexibility and hydrolysis resistance reduce the risk of cracking or hardening over time, which can lead to leaks and downtime. Its compatibility with energy chains makes it a reliable choice for moving cable carriers, robotic arms, and other dynamic applications.
When selecting tubing for a new system, engineers should consider the operating pressure, temperature range, and medium. This Festo tubing covers a broad spectrum, from standard compressed air lines to water-based cooling circuits. The black color may also be preferred in applications where UV resistance or a specific aesthetic is required, though this is not explicitly stated.
Practical Selection Considerations
For procurement teams, the PUN-H-10X1,5-SW-25 is available in a 25-meter length, which is a common unit for prototyping and small-scale production. The product weight of 0.0465 kg/m helps in estimating shipping costs and handling. The tubing's compliance with TÜV and RoHS standards simplifies regulatory approval in many markets.
Engineers should note that the operating pressure varies with temperature, so it is crucial to check the pressure-temperature diagram for the specific application. For water use, the pressure is limited to 0.3 MPa at 0–60 °C, which is lower than for compressed air. This distinction is vital to avoid over-pressurization in liquid systems.
In summary, the Festo PUN-H-10X1,5-SW-25 offers a balance of flexibility, durability, and compliance, making it a solid choice for a wide range of pneumatic and fluid handling tasks. Its suitability for energy chains and food-grade applications adds to its versatility, while the clear technical parameters allow for precise system design.
