Our stainless mandrel bends are the bends of choice for high end header fabricators. What makes our mandrel bends different is the tubing we start off with. Made from an American made 321 stainless and bent in the U.S., they are the best mandrel bends on the market. Easy to fabricate with, they expand without cracking. This ability to form is essential when fitting the tube to your flange. Since we use an annealed 321 stainless, our mandrel bends can be shaped to fit the most complex of header flange shapes without cracking. This domestically made material welds superbly and doesn’t rust like 400 series stainless.
