AC PERFORMANCE Aluminum 4AN Flare to 1/4 NPT Male Hose Fitting Adapter Union Fuel Oil Line Pipe Connector, JIC 4AN 7/16-20 Male Flare to 1/4 NPT Male Thread Black Anodized

Decent fitting-Ended up needing to remove the NPT fitting and stripped most of the threads- no leaks or cross threading but aluminum is quite soft- just use caution and don’t over tighten and I’m sure you’ll be fine

Just what I needed for my oil cooler thanks

AN fittings rock

Used these on my fast fuel injection fuel pump kit. The pump has 1/8 pipe and comes with 6 an fittings. My fuel cell has 8an so this worked out perfect.

Exactly what I need it, To work my gas line on my ls swap.

Works great so far!

Best diesel fittings

Great fittings.

As advertised, fits great.

Fits and seals good, installed for turbo drain on an LS swap.
