• Food and Beverage Machinery
When selecting a sealing solution, comparing TESNIT BA-U to alternative materials is crucial. Compared to traditional graphite packing, TESNIT BA-U offers superior chemical resistance and lower friction. While rubber seals are cost-effective, they lack the temperature and pressure resistance of PTFE-based materials like TESNIT BA-U. Spiral wound gaskets provide excellent sealing but can be more expensive and complex to install. TESNIT BA-U strikes a balance between performance, cost-effectiveness, and ease of installation, making it an ideal choice for a broad range of applications.
| Material | Temperature Resistance | Chemical Resistance | Cost |
|---|---|---|---|
| TESNIT BA-U (PTFE) | -200°C to +260°C | Excellent | Medium |
| Graphite Packing | Up to 500°C | Good | Low |
| Rubber Seals | -50°C to +150°C | Limited | Very Low |
| Spiral Wound Gaskets | -200°C to +700°C | Excellent | High |
Understanding the technical specifications of TESNIT BA-U is crucial for selecting the right size and type for your application. The material is composed of pure PTFE fibers, offering exceptional chemical inertness. It is available in various cross-sectional shapes (square, round, and rectangular) and sizes to accommodate different gland dimensions. The lubricant impregnation enhances sealing performance and reduces friction.

TESNIT BA-U represents a superior solution for a wide range of sealing applications. Its exceptional chemical resistance, high-temperature capabilities, and low friction make it an ideal choice for demanding industrial environments. By choosing TESNIT BA-U, you are investing in reliability, durability, and optimal performance. Contact us today to discuss your specific sealing needs and discover how TESNIT BA-U can benefit your operations.
TESNIT BA-U can withstand pressures up to 300 bar (4350 psi), depending on the flange design and sealing conditions. The braided construction and the material’s inherent properties contribute to its ability to maintain a tight seal under high pressure. However, it's important to consult with our technical team to ensure the appropriate size and installation technique for your specific pressure requirements. Proper gland design and tightening are crucial for maximizing pressure resistance.
Yes, TESNIT BA-U is manufactured from pure PTFE, which is an FDA-approved material for food contact applications. This makes it suitable for use in the food and beverage industry, where hygiene and safety are paramount. However, it's important to ensure that the lubricant impregnation is also food-grade compliant. We offer specific versions of TESNIT BA-U designed specifically for food-grade applications – please contact us for details.
Determining the correct size requires measuring the gland dimensions where the packing will be installed. You'll need to measure the shaft diameter and the gland depth. It’s generally recommended to select a cross-sectional shape and size that provides a slight interference fit to ensure a tight seal. Our technical team can provide guidance and recommend the appropriate size based on your specific application requirements. Detailed sizing charts and instructions are also available on the GZHTMF website.
TESNIT BA-U has a long shelf life when stored correctly. It should be stored in a cool, dry place, away from direct sunlight and contaminants. Typically, it can be stored for several years without significant degradation of its properties. However, we recommend checking the packaging for specific expiration dates and following our storage guidelines to ensure optimal performance.
