Stainless Steel Adapters

Complete your sanitary process system with one of CSI's many styles of adapters in stainless steel. We stock a wide variety of sizes, types, and connections in our three US warehouses.

At CSI, we ensure that our stock of sanitary adapters meets stringent quality standards for a hassle-free installation. Our multiple adapter options mean that you can easily tie in to supply lines or make other transitions.

For adapter options with even more corrosion resistance, CSI also offers AL-6XN® Alloy Adapters and Hastelloy® C-22® Adapters.

Some items are 3-A approved as noted.

Pipe Adapters

CSI's pipe-to-tube adapters smoothly transition between 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 10
  • Standard pipe bevel on Schedule 40
  • Reducing sizes are also available
