Blue Anodized Aluminum Adapter, -06 Male JIC 37 deg Flare To 1/4 Inch Male NPT, 90 deg Elbow

This adapter is suitable for use with hydraulic oil. For specific fluid compatibility, it's best to consult the fluid compatibility document available on the product page.

That's the kind of situation this adapter handles. One end is 1/4 inch male NPT and the other is a -06 male JIC 37-degree flare, and the 90-degree elbow geometry lets you make that direction change at the connection point itself instead of stressing the hose or tube. Eaton Aeroquip makes this one under catalog number C1CQ36, so sourcing or cross-referencing it later is pretty straightforward.
