We manufacture our weldable tee tube fittings from 304 series stainless steel. Weld tube fittings are ideal for use as roughing lines on semiconductor process equipment and for foreline and pump exhaust lines in semiconductor subfabs.
Weldable Tees Feature:
- Maximum cleanliness for UHV applications to > 10-13 Torr
- Fabricated using pulled-port technique with full penetration butt welds
- Crevice-free weld joints
- Reducer tees adapt two different tube sizes
- Common wall thicknesses and tube diameters listed; contact us with your specific requirements or for flanged versions
