Fragola -16AN x 1 5/16-16 (16) Radius Fitting

This Fragola radius fitting uses a 1 5/16-16 thread size on one end and a -16AN size on the other. It’s made from aluminum, which keeps the weight down and makes it easy to work with for custom fuel or oil line setups. The radius design helps smooth out fluid flow compared to a sharp 90-degree bend, which can reduce turbulence and pressure drop in your system.

You'll find fittings like this are common when fabricating custom hard lines for oil coolers, fuel rails, or other fluid transfer systems where you need to connect different thread types or change direction smoothly. The aluminum construction means it's best suited for applications where high temperatures or extreme pressures aren't the primary concern, but it's a solid choice for many engine bay setups.
