Aluminum Bent Elbow 2.500 180-Degree

The Aluminum Bent Elbow 2.500 180-Degree from Woolf Aircraft Products is a precision-engineered tubing bend designed for high-performance automotive cooling, intercooler, and custom intake manifold applications. Built by mechanics and fabricators who understand the critical role of flow efficiency in engine performance, this 180-degree mandrel bend allows you to redirect coolant, charge air, or fuel lines with minimal turbulence and pressure loss. Whether you're upgrading a turbo system, constructing a custom radiator hose setup, or designing a complex cooling circuit, this bent elbow eliminates the need for multiple fittings and reduces potential leak points in your plumbing.

Manufactured from 6061-T6 aluminum alloy with a 0.065-inch wall thickness, this component delivers excellent strength-to-weight ratio while resisting corrosion in demanding under-hood environments. The 2.5-inch inner diameter accommodates substantial flow volumes typical of modern turbocharger and supercharger setups, while the 3-inch bend radius ensures smooth, laminar flow characteristics that preserve pressure and reduce heat generation across the bend. The mandrel bend process—a technique also employed in aircraft hydraulics and racing fuel systems—creates uniform wall thickness throughout the bend, preventing the wall collapse and flow restriction that can occur with cheaper tube-bending methods. Natural anodized finish provides base protection while allowing for custom coating or finishing to match your engine bay aesthetic.

This bent elbow suits custom fabrication projects, performance cooling system upgrades, and OEM-style replacements where factory rubber hoses are no longer adequate. Experienced builders favor aluminum tube bends over welded steel alternatives for reduced weight and easier integration with modern turbo kits, intercooler piping, and fuel bypass loops. Weighing just 1.05 pounds, it minimizes underhood mass while delivering durability comparable to aircraft-grade hydraulic components. Compatible with standard hose clamps, compression fittings, and flange adapters in the 2.5-inch family, this bend integrates seamlessly into both street and race applications requiring reliable, efficient flow paths under boost and high-temperature conditions.
