More Ferrules


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 Stainless ferrules that meet 3-A sanitary or BPE standards, visit the Ferrules for Food, Dairy, & Beverage and BPE Ferrules pages. CSI also offers AL‑6XN® Alloy Ferrules as another corrosion resistant option.
