If you’re diving into a custom project, this HPS 1-5/8" 90 Degree Bend Aluminum Elbow is a solid choice. Made from 16-gauge 6061-T6 aluminum, it’s tough yet lightweight, which is exactly what you want for anything from DIY air intakes to turbo intercooler piping setups. Trust me, this stuff is the go-to for a reason—6061 aluminum is versatile and cost-effective, making it a favorite among fabricators.
Now, let’s talk specifics. This elbow has a 6" leg length on each side and a 2" center line radius, which means it fits snugly into tight spaces while still allowing for smooth airflow. The outside diameter is 1-5/8" (or 41mm), with a wall thickness of 0.065" (1.65mm), so it’s sturdy enough to handle the rigors of automotive and marine applications without breaking a sweat.
One thing to keep in mind: while you can polish this aluminum, you’ve got to be careful not to take off too much material, especially around the welds. It’s soft, so just a little too much elbow grease can compromise the integrity. And just to clarify, HPS doesn't recommend using this aluminum for exhaust systems—it's really not built for that heat.
Oh, and all this tubing is made right here in the USA, which is a nice touch if you’re into supporting local manufacturing. Whether you're a hobbyist or a seasoned pro, this elbow is ready to help you tackle your next project with confidence.
