3-1/2 x .065 Tubing 180 Degree Mandrel Bend

The Stainless Works 3-1/2 x .065 tubing 180 degree mandrel bend is essential for professional exhaust fabrication, intake manifold construction, and custom cooling system plumbing. It is designed for welders, fabricators, and serious enthusiasts who require precise tube routing without kinks or wall collapse.

This mandrel bend ensures smooth flow characteristics that are critical to engine performance. The mandrel bending technology maintains wall thickness uniformity throughout the entire radius, contrasting with crush bending, which compresses one side while thinning the opposite wall. The 180-degree profile allows for U-shaped routing, which is essential in tight engine bays and complex plumbing layouts.

At 3-1/2 inches outer diameter with .065-inch wall thickness, this tubing strikes the ideal balance between structural integrity and workability for both TIG and MIG welding. Stainless Works' precision manufacturing ensures consistent bore geometry and surface finish, reducing turbulence and maximizing flow efficiency in high-temperature applications. This mandrel bend is suitable for fabricators building full exhaust systems, turbocharger manifolds, wastegate plumbing, intake manifolds, and custom cooling loops.
