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.

*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.

Pipe Adapters

CSI's pipe-to-tube adapters smoothly transition from schedule pipe sizes to OD tube sizes with either a butt weld or Tri-Clamp tube connection.

Features
  • Tapered for smooth flow
  • Squared ends (for single-pass fusion welding) in Schedule 5 and Schedule 10
  • Standard pipe bevel on Schedule 40
  • Reducing sizes are also available
