Great quality fittings — EVIL ENERGY never disappoints
I really like EVIL ENERGY products. These 10AN PTFE fittings are solid, well-machined, and the finish looks great. The threads are clean, the swivel is smooth, and everything tightens down perfectly. I’ve used EVIL ENERGY on several parts of my build and I’ve never had a single leak or issue. The quality is always consistent, and for the price they’re hard to beat. Definitely a brand I trust and will keep using.

Evil Energy stuff is great, I have bought alot, now, all different sizes, no disappointments.
As with all the Evil Energy stuff, works great. Bought a different name brand stuff kit, and end up replacing all leaking fittings with Evil Energy stuff.

Perfect and no surprises
Just as described, ran some of their 5/16 steel braided line and is flawless. No instructions but there were instructions in the hose. Order all my hose and fittings from EVIL ENERGY and will continue to do so!

Looks and works well
As always, we use Evil Energy fittings on all our race cars and have never had any issues with fitment, quality or longevity. Much cheaper than the other brands and these are tough fittings.

Well worth it
I am very pleased. Worked perfectly and don’t leak a drop. Easy to do. My first time ever doing these and I was very satisfied. I actually used this to make a repair for a hardline that got damaged and had to make a splice. Used compression fittings and it works flawlessly.

I was a little hesitant to purchase the evil energy stuff because of the price. I ordered 2 kits for an Ls swap for all the lines and fittings to do my muscle car. It turns out to be excellent quality and easy to put together. In total I used 16 fittings and almost 30’ of -8 fuel line. Everything is great. Will definitely buy more from evil energy
