Overview and Key Characteristics
The Festo PUN-H 3/8" TGE-150-CB (manufacturer ID 8203979) is a polyurethane-based pneumatic tubing engineered for demanding industrial environments. Its translucent yellow color and 3/8-inch external diameter make it easily identifiable during installation and maintenance. The tubing is made from TPE-U (PU) and is RoHS-compliant, ensuring it meets modern environmental standards.
One of the standout features is its flexibility, which is critical for complex piping layouts. The minimum bending radius is 24.994 mm, while the bending radius relevant for flow rate is 52.121 mm. This allows for tight bends without kinking, preserving airflow and reducing the risk of blockages. The tubing is also suitable for energy chains, making it a reliable choice for moving applications such as robotic arms or automated machinery.
Performance Under Pressure and Temperature
The PUN-H tubing is rated for a temperature-dependent operating pressure range of -0.993 bar to 9.997 bar. For compressed air applications, it can handle pressures up to 0.3 MPa when the ambient temperature is between 0°C and 60°C. This makes it suitable for standard pneumatic systems that operate within these parameters.
The tubing also demonstrates resilience across a wide ambient temperature range, from -35°C to 63°C. This broad range ensures reliable performance in both cold and warm environments, which is often a requirement in industries like automotive manufacturing or food processing. Additionally, the material has a Shore hardness of D 52 ±3, striking a balance between rigidity and flexibility.
Chemical Resistance and Media Compatibility
This tubing is engineered to resist a wide range of chemicals, making it suitable for applications where exposure to oils, solvents, or mild acids is possible. It is compatible with compressed air as per ISO 8573-1:2010 [7:-:-] and can also handle water (liquid, ice-free). This dual-media capability expands its usability in both pneumatic and fluid transfer systems.
For industries with strict cleanliness requirements, the tubing meets LABS (PWIS) conformity to VDMA24364-B2-L, ensuring it does not release substances that could contaminate painted surfaces. It also holds a UL94 HB fire rating, adding a layer of safety in case of fire exposure.
Installation and Integration Benefits
The smooth inner surface of the PUN-H tubing reduces friction, which simplifies installation and minimizes pressure drop. It is designed for plug connections with an outside diameter of 3/8 inch, allowing for quick and secure fittings without the need for special tools. This can significantly reduce setup time and labor costs, especially in large-scale installations.
The tubing's lightweight nature (0.48 kg/m) further eases handling and routing. Its suitability for energy chains means it can withstand repeated flexing, making it ideal for dynamic applications. For industries involved in Li-ion battery production, note that the tubing is compatible, provided that metals with more than 1% copper, zinc, or nickel are excluded from the surrounding environment.
Selection Considerations for Engineers and Buyers
When selecting pneumatic tubing, it is essential to verify that the operating pressure and temperature ranges align with your system's specifications. The PUN-H 3/8" TGE-150-CB is a robust option for general automation, process control, and manufacturing equipment. Its chemical resistance and compliance with food industry guidelines (see supplementary material) make it a versatile choice.
For cleanroom applications, note that as a statically installed element, no meaningful cleanroom classification can be assigned per ISO 14644-1. If your project requires specific certifications or material approvals, always consult the latest technical documentation from Festo to confirm suitability.
