TFM Weldable Cross Tube Fittings
TFM manufactures top-tier weldable cross tube fittings using 304 series stainless steel, specifically designed for semiconductor process equipment. These fittings are ideal for roughing lines, foreline, and pump exhaust lines in semiconductor subfabs.
Features of Weldable Crosses
- Superior Cleanliness for UHV Applications: Designed to meet the strict cleanliness standards for ultra-high vacuum (UHV) environments, down to > 10<sup>-13</sup> Torr.
- Advanced Fabrication Process: Built using the pulled-port technique, ensuring full penetration butt welds that enhance the strength and durability of each fitting.
- Crevice-Free Welds: Crevice-free joints minimize contamination risks, making these fittings reliable for critical applications.
- Wide Temperature Range: Suitable for use in environments ranging from -200 °C to 450 °C, providing flexibility in diverse conditions.
- Reducer Crosses for Adaptability: Reducer crosses allow for easy connection between two different tube sizes, offering versatility in system design.
- Custom Sizing Available: While common wall thicknesses and tube diameters are listed, we offer custom sizing options and flanged versions based on specific needs.
