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.

*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 (0.6 µm) maximum finish for sizes ½ – 4 inch diameter. 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.
