6AN Aluminum Weld On Fitting

Welding this on was straightforward, and the aluminum feels solid—no leaks on my custom fuel line setup.

The 6AN male flare sealed perfectly on my first weld, no leaks at all. Having the weld-on option made my custom fuel rail setup much cleaner than using adapters.

Finally, a weld-on fitting that actually has enough wall thickness to hold up to some heat and vibration without distorting. The threads are clean and the sealing surface is nice and sharp.
