Achieve tighter radius bends with ease using our 6061 Aluminum Donuts—perfect for custom fabrication projects like intercooler piping, intakes, and more. These donuts are engineered to retain consistent wall thickness where traditional tight radius mandrel bent tube can be inconsistent due to the bending process.

Features:

• High-Quality Material: Precision-crafted from 6061 Aluminum for superior performance and durability.

• 14 Gauge Wall Thickness: Ensures structural integrity and ease of welding.

• Tight Radius: Ideal for fabricators who need a tighter CLR for their designs.

• Available Sizes: Options for various diameter and centerline radius (CLR) configurations.

Center Line Radius:

2" - 2" CLR
2.5" - 2" CLR
2.75" - 2.2" CLR
3" - 2.3" CLR
3.5" - 2.5" CLR
4" - 2.8" CLR

*Donuts sold as 2 halves unwelded
