About Woolf Aircraft Products, Inc.
Few names in precision tube fabrication carry the same weight as Woolf Aircraft Products, Inc. Founded in 1942 and headquartered in Romulus, Michigan — just minutes from Detroit Metropolitan Airport — Woolf Aircraft has spent more than eight decades perfecting the craft of tube bending, forming, and welding. What began as a specialist supplier to the aerospace industry has grown into a trusted resource for thousands of customers across automotive, defense, marine, motorsport, and industrial markets.
The company operates out of a modern 94,000-square-foot facility and stocks over a thousand different types and sizes of tubing materials — including stainless steel, aluminum, carbon steel, titanium, Inconel, and brass — all held to Military, AMS, and ASTM standards. Whether a customer needs a single prototype piece or a production run of 40,000 units, Woolf Aircraft scales to meet the demand with the same commitment to quality.
A Full Spectrum of Fabrication Capabilities
Woolf Aircraft's capabilities extend far beyond simple tube cutting. Their in-house services span beading, boring, brazing, expanding, flanging, flaring, hydroforming, machining, milling, stamping, surface grinding, TIG welding, and more. This breadth allows them to take a project from raw material to a finished, ready-to-install assembly without farming out critical steps — an advantage that translates directly into tighter tolerances and more consistent quality.
The company is certified to both ISO 9001:2015 and AS9100D standards, reflecting a rigorous quality management framework developed across decades of serving commercial, military, and aerospace customers. Their specialty in thin-wall, tight-radius configurations has earned them a particular reputation for tackling bends that other fabricators consider too difficult.
Exhaust Elbows & Performance Tube Assemblies
For automotive and performance enthusiasts, Woolf Aircraft is perhaps best known for its line of pre-bent elbows, exhaust elbows, collectors, flanges, and header kits. These parts are built from the same aerospace-grade processes that define everything Woolf does — mandrel-bent for smooth interior radii, available in stainless steel, aluminum, and mild steel, and sized from small-diameter performance tubing up to 5½" outside diameter in stock configurations. Fabricators, engine builders, and custom exhaust shops rely on Woolf elbows as the foundation for high-quality, unique exhaust systems that demand precise, consistent geometry.
Their collectors are CNC-milled and TIG-welded by certified welders from 16-gauge 304 stainless steel, while their laser-cut stainless flanges are typically kept in stock for fast turnaround. Standard header kits are offered in 304 stainless steel and 1010 mild steel, making Woolf Aircraft a one-stop resource for builders putting together a complete exhaust system from scratch.
Serving Dozens of Industries with One Standard of Quality
Beyond the performance world, Woolf Aircraft tube assemblies find their way into aircraft hydraulic and fuel systems, naval vessels, heavy trucks, turbine engines, military tracked vehicles, and marine exhaust applications. This cross-industry experience means their engineering team understands real-world demands — vibration, heat cycling, corrosion, and pressure — not just blueprint tolerances. For anyone who needs a tube done right, Woolf Aircraft Products has been the answer since 1942.
