Hastelloy® C-22® Adapters

Hastelloy C-22 pipe adapters allow you to more smoothly connect pipe to tube, tube to hose, ferrule to tube, and more. Choose from butt weld or Tri-Clamp® connections. CSI's large variety of adapters provide more flexibility to build your corrosion resistant process line how you want it.

For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks 304 and 316L Stainless Steel Adapters. We also offer AL-6XN® Adapters as another corrosion resistant option.

Length dimensions are consistent with industry standards.

More Adapters

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 and 316L adapters that meet 3-A sanitary or BPE standards, visit the Adapters for Food, Dairy, & Beverage page. CSI also offers AL-6XN® Alloy Adapters.
