If you're into custom fabrication—whether it's an air intake, intercooler setup, coolant line, or a marine project—this 90-degree aluminum elbow is a super handy piece. It's made from 6061-T6 aluminum, which is strong, lightweight, and easy to work with. The outside diameter is 1 inch (25mm) with a wall thickness of 0.065 inches (16 gauge), so it's sturdy without being overly heavy. Each leg measures 6 inches long, and the centerline radius is 3 inches, giving a smooth, consistent bend that won't restrict flow. Perfect for DIYers, car enthusiasts, or small shop projects where you need a reliable, seamless bend that can be polished, welded, or machined. Works great in automotive, marine, aerospace, or industrial applications. Just remember—it's not recommended for exhaust systems due to the alloy's limits with high heat. Whether you're building a turbo piping kit, a custom radiator line, or a unique air system, this elbow helps you get a clean, professional look without breaking the bank. Sold ready to use, no finishing required unless you want to polish it up for show.
