AL-6XN® Alloy Elbows

With a variety of options to choose from, Central States Industrial (CSI) will help you find the elbow you need.

  • AL-6XN® elbows are available in 90º, 88°, 92°, and 45º options. You have a choice of butt weld or clamp style connections. Elbow connection styles come in several combinations: butt weld x butt weld, Tri-Clamp® x Tri-Clamp, and butt weld x Tri-Clamp.

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

Dimensions are consistent with industry standards.
