In 2014, Pro-Flex was acquired by the ownership of Sioux Chief Manufacturing. Based in Hillsboro, Indiana,
Pro-Flex offers a corrugated stainless steel tubing (CSST) system for natural or propane gas that offers a flexible,
labor-saving alternative to black steel pipe installations. Rigid steel installations require numerous fittings
and cutting and threading of pipe which is extremely labor intensive. The fitting system and flexible quality of
CSST eliminates the costs inherent with black steel pipe – labor savings alone can be up to 75%. Pro-Flex has
been providing their tubing, fittings, and accessories to the plumbing, heating, propane & natural gas markets
for more than 20 years.
