AL-6XN® Alloy Adapters

When you need to transition between different line types (pipe, tube, hose, etc.), AL-6XN offers the corrosion resistant solution. CSI's AL-6XN pipe adapters allow you to solve the problem of connecting tube to pipe. The flange adapters are used for attaching sanitary ferrules to pipe, and the hose barb adapters can help you easily connect your tube to hose.

For applications that require 3-A sanitary standards or ASME-BPE standards, CSI stocks 304 and 316L Stainless Steel Adapters. We also offer Hastelloy® C-22® Adapters for more corrosion resistance.

Length dimensions are consistent with industry standards.
