BOOST Products 90° Aluminium Cast Elbow - tight radius

Tight aluminum cast elbow pipe

BOOST Products cast aluminum arch with tight radius

PLEASE NOTE: The cast aluminum metal could contain small burrs and leftover casting residue/slag. This is normal and not a product defect, it's a natural side effect of the casting process. You may need to grind this away with the proper tools to smooth out the imperfections before installation.

When aluminum or silicone connections just won't cut it for your application, these elbows are engineered for tight engine bays and high-boost applications. The BOOST Products USA Cast Aluminum Elbow delivers maximum structural integrity where standard mandrel-bent tubing may fall short.

Featuring heavy-wall construction and smooth internal walls, this cast elbow offers good airflow, strength in extreme pressure, and TIG weldability for custom charge pipe plumbing.

Key Features & Performance Benefits

• Tight-Radius Engineering: Precision-cast for sharp angles in cramped engine compartments to maintain flow efficiency without collapsing under vacuum.
• Heavy-Wall Durability: Thicker wall profile over thin-wall aluminum tubing ensures maximum resistance to any kind of abuse.
• Optimal Flow Efficiency: Smooth inner diameter minimizes air turbulence across your intake or intercooler piping.
• Effortless Weldability: High-grade cast aluminum alloy allows for clean, high-strength TIG welding directly to intercooler end tanks, turbo compressor housings, or custom piping.
• Secure Coupler Retention: Each comes bead rolled to keep any silicone you decide to run in place under high intake or vacuum loads.

Fabricator's Advantage: Cast vs. Mandrel Bends

Standard mandrel-bent aluminum tubing requires a wide bend radius to prevent wall collapse during manufacturing. BOOST Products USA Cast Aluminum Elbows allow for an extremely tight centerline radius, giving you maximum clearance around frame rails, radiators, and engine accessories while maintaining rock-solid structural rigidity under extreme boost levels.
