Flanges

ProFabrication stocks CNC Header Flanges for a variety of head types, including: Ford, Chevrolet, Dodge, and imports such as Honda, Toyota, BMW, Mitsubishi, Porsche, VW and Ferrari.

ProFab stocks 3-Bolt Flanges in a variety of diameters. We also have 3D flanges available.

All CNC Header Flanges are machined on precision equipment. All header flanges are made from 3/8" or 1/2" thick 1018 cold roll steel or 304 Stainless Steel. They are made of 304L material and some require heat treating. The lower carbon content of these flanges allows for easier weldability.
