EVIL ENERGY 6AN Male to 3/8" Hardline Compression Fitting Adapter, 2 PCS

Good stuff! There’s no easier or more cost affective way to convert a 3/8” hard line into braided line than this. I used one of these to convert the feed line out of my fuel sending unit into a 6an line. Worked perfectly, was easy to install, looks great and seals up tight. Love it!

Trans oil cooler lines leaked as GM lines always do at the "rubber to metal line crimp"..Replacement's do the same thing so I cut them out at the leaking factory crimp and used these compression fitting to 10AN with a left over hose fitting kit I had and these worked great and a lot cheaper than a factory replacement line or after market..Just make up a hose kit available here and use these to adapt to the 5/8" metal tube after you cut out the factory rubber hose with crimp. a good solid fix that will never leak...

Amazing product ! So easy to use , i thought they might leak but nothing ! I definitely plan on buying more.

Worked perfect for a square body Chevy pickup that is being Ls swapped easy to use and seam to be of good quality for the price thank you

Quality piece. Firings worked great. Would buy again.

Worked great for my c10 LS swap sending unit !

Prefect fit for my box Chevy

Used this to run steel braided line with -6an fittings to the hard line on my fuel tank. Quality parts for the money.

As with all Evil Energy fittings I’ve purchased, they’re reasonably priced and perform the job there supposed to.

this is a excellent value for money. Im a thirty year commercial aircraft mechanics who has seen a few line fittings. These are very good value and I will continue to use this brand.

Not Evil Energy ,very disappointed.

Fast delivery, part as expected, cheaper than other places. We'll see how it holds up.

Good item
