AL-6XN® Alloy End Caps

Complete your sanitary process system with sanitary, AL-6XN® alloy end caps from Central States Industrial (CSI). We stock sizes ½ – 4 inches in Tri-Clamp® and butt weld connections.

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

*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.
