If you're diving into the world of AN fittings, you know how important it is to have reliable components. The HPS AN Flare Plug is one of those pieces that really makes a difference. I’ve had my fair share of experiences with various plugs, but this one stands out. It’s precision machined, which means you can count on it for a smooth thread engagement every single time. No more wrestling with fittings or worrying about leaks—this plug gives you a tight, leak-free seal that you can trust.
What I really appreciate is the Type II anodized black finish. Not only does it look sharp, but it also holds up well against corrosion and scuffs. You want your components to look good, but they also need to withstand the elements, and this plug does just that. It’s made from forged 6061 aluminum, which is tough enough to handle the rigors of fuel, oil, coolant, and even nitrous. So whether you’re building a high-performance engine or just need something reliable for your daily driver, this plug has you covered.
Now, let’s talk specs. This one is an AN-12 size, which means it installs onto female 37-degree AN flare fittings seamlessly. The compatibility with various fluids—fuel, oil, coolant, alcohol, nitrous, and hydraulic fluid—makes it super versatile. Plus, the black color keeps things looking sleek and clean under the hood.
In short, if you're in the market for a solid flare plug that won't let you down, the HPS AN Flare Plug is worth considering. It’s practical, durable, and has that extra touch of style that makes it a great addition to any setup.
