Hastelloy® C-22® Tees & Crosses

CSI stocks hundreds of corrosion resistant Hastelloy C-22 tees that include standard and made-to-order items. Choose from butt weld or Tri-Clamp® connections, then decide if you want a tee, reducing tee, or instrument tee. Lengths and dimensions are consistent with industry standards.

For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks 304 and 316L Tees & Crosses for Food, Dairy, & Beverage and BPE Tees & Crosses. We also offer AL-6XN® Tees and Crosses as another corrosion resistant option.

Length dimensions are consistent with industry standards.

More Tees


Typically, CSI stocks butt-weld fittings. If you're looking for a different connection, we can also provide Tri-Clamp, I-line, SMS, or DIN options. Most of our fittings are offered in standard BPE dimensions. At CSI, we stock polished fittings, and unpolished fittings are available upon request.

For 304 or 316L tees that meet 3-A sanitary or BPE standards, visit the Tees & Crosses for Food, Dairy, & Beverage and BPE Tees & Crosses pages. CSI also offers AL-6XN Alloy Tees and Crosses.
