3.0″ Aluminum Welding Fabrication Donut Tight Bend Radius (Welded Outside)

Our aluminum donut is designed for custom fabrication of custom throttle body to intercooler connection, turbo compressor outlet, intercooler inlet and outlet, intercooler pipes, intake manifolds and more where space is extremely limited. These aluminum donuts allow you to fabricate very tight radius bends which are impossible to achieve with a mandrel tube bender.

Reasons to choose aluminum donut for your build:

1. Tight bends achieved
2. Huge time savings vs Pie Cuts
3. Much better flow than Pie Cuts
4. Can be cut at any angle to produce a bend up to 180°
5. Virtually no preparation needed prior to welding
