120 Degree Tight Radius Aluminum Bend 3.5in OD

The 120 Degree Tight Radius Aluminum Bend 3.5in OD from Vibrant Performance is an essential component for custom exhaust, intake, and coolant line routing in high-performance engine builds. Whether you're fabricating a turbo manifold, constructing a custom cooling system, or designing a bespoke intake tract, this tight-radius bend allows precise directional changes in confined engine bays where standard bends fall short. Built for builders and tuners who demand precision and reliability in their custom plumbing solutions, this component eliminates the need for multiple elbows or welded custom bends.

Constructed from aluminum alloy, the 120 Degree Tight Radius Aluminum Bend features a 3.5-inch outer diameter and maintains a tightly controlled bend radius that preserves internal flow area while maximizing space efficiency. The 120-degree geometry provides the sharp directional change required in modern engine bay layouts without the turbulence and flow loss associated with sharp elbows. Vibrant Performance's engineered design ensures consistent wall thickness and smooth internal transitions, critical for minimizing pressure drop in high-flow applications like intercooler piping, radiator hose runs, and forced-induction systems. Lightweight aluminum construction reduces unsprung weight and simplifies installation compared to steel alternatives.

This bend suits engine builders, suspension tuners, and fabricators tackling LS swaps, turbocharged platforms, and custom cooling system designs where off-the-shelf solutions don't fit the application. At 1.37 lbs, it integrates seamlessly into weight-sensitive builds without sacrificing structural integrity or flow characteristics. Compatible with standard 3.5-inch hose and tubing systems, it mates directly with existing piping infrastructure and mandrel-bent tubing. Installation is straightforward for welding or brazing; ensure proper surface preparation and use appropriate filler materials for your specific application to guarantee long-term durability under thermal and pressure cycling.
