Weld Fittings – Clean, Reliable Connections for Vacuum Systems

Our Weld Fittings are a trusted choice for vacuum roughing lines, especially in semiconductor process equipment where cleanliness and durability are critical. Designed for high-performance environments, these fittings help reduce the number of sealed joints—ideal for permanent house vacuum lines.

All tees and crosses are manufactured using the pulled-port technique and full penetration butt welds, resulting in crevice-free joints that meet the highest standards for Ultra-High Vacuum (UHV) applications.

Material Options:

• Standard: 304 Stainless Steel
• Select sizes also available in 316L Stainless Steel for enhanced corrosion resistance

Surface Finishes

• Standard Finish: Tumbled for a clean, uniform surface
• Bead-Blasted Finish: Available on select fittings (identified by a “-B” suffix)
