Hastelloy® C-22® Tees & Reducing Tees

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 as another corrosion-resistant option.

Length dimensions are consistent with industry standards.

*20/32 µ-inch Max Ra is an approximate value and is not guaranteed. Surface finish roughness shall be physically examined for “P25” using a profilometer calibrated to standards traceable to NIST. Surface finish roughness shall NOT be subject to physical examination for “P7” or “7”.

**The interior surfaces shall be mechanically polished or as drawn to a 25 Ra µ-inch (0.8 µm) maximum finish for sizes ½” to 4” diameter (where available). The electropolishing process may increase the Ra values post electropolishing and have areas of preferential etching (e.g. frosting, shadowing, etc.). Final Ra values for electropolished tubing and fitting shall not be used as criteria of acceptance for this product.

***Sanitary Finish: Offering finish better than traditional commercial grade tube finish. Suitable for applications in sanitary/high purity hygienic industries.

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.
