Fragola -3AN x 1/4 NPT Adapter

When you're building a custom fuel system or need to adapt a brake line, getting the right fittings is key. This adapter from Fragola lets you connect a -3AN (also known as a 3/8"-24 inverted flare) fitting to a port that uses 1/4" NPT (National Pipe Taper) threads. It's a common need when you're working with aftermarket fuel pumps, regulators, or gauges that use standard pipe threads.

This adapter is made from aluminum, which keeps the weight down and makes it easy to work with. The -3AN side has the standard fitting for braided hose assemblies, and the 1/4" NPT side is tapered to create a seal as you thread it in. Just make sure the port you're connecting to is clean and free of debris before you install it. A little bit of pipe thread sealant can help ensure a leak-free connection, but be careful not to use too much, as it can get into the fluid system.
