Fittings are formed from material that meets the same exacting standards as our process tubing. We begin the process with a heavier wall to offset the thinning that occurs during manufacturing. Cardinal UHP fittings undergo a thorough preparation process to insure corrosion resistance as well as stringent dimensional specifications for economical installation.
