The HKS universal aluminum bend is a 50mm, 30-degree tube bend listed as -1.5D for fabrication projects and custom plumbing. It offers a shallow directional change with a longer radius implied by the -1.5D designation, suitable for smoother transitions in intake or intercooler piping runs where reduced turbulence or clearance is desirable.
