AL-6XN® Alloy Ferrules

CSI stocks hundreds of AL-6XN ferrules in a wide range of sizes and lengths to ensure you get the fitting that fits your application. We carry short, medium, and long ferrules, as well as ferrules with heavy or extra-heavy wall thicknesses. CSI also stocks SMS fittings, DIN 11864 fittings, and DIN 32676 fittings.

For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks 304 and 316L Ferrules for Food, Dairy, & Beverage and BPE Ferrules. We also offer Hastelloy® C-22® Ferrules for more corrosion resistance.

Length dimensions are consistent with industry standards.
