If you’re diving into the world of automotive performance, you know that keeping things leak-free is key. That’s where the HPS AN to Metric adapter comes in. This little gem is a game changer, especially if you’re working with those pesky metric fittings that seem to need a washer swap every time you service them. With this adapter, you can easily convert your female metric threads to a male AN style fitting, making your life a whole lot easier when it comes to repeated serviceability.
What I really appreciate about these AN style fittings is how user-friendly they are. You can install and remove them multiple times without the hassle of messing around with extra sealants or gaskets. It’s all about keeping it simple, right? Plus, the HPS adapter is crafted from 6061 aluminum and features a Type II black anodized finish. This means it not only looks sleek but also holds up against abrasion and corrosion like a champ.
Let’s break down the specs a bit. You’ve got an AN-6 on one side, and it connects to a M20 x 1.5 metric thread on the other. That’s a solid setup for anyone who’s serious about their build. The package even includes an aluminum crush washer to ensure a tight seal, so you can focus on what really matters—getting your ride back on the road.
And don’t worry about compatibility; this adapter works with a variety of fluids—fuel, oil, coolant, alcohol, nitrous, and even hydraulic fluid. It’s versatile enough to handle whatever you throw at it. So, if you’re looking to upgrade your connections while keeping everything leak-proof, the HPS AN to Metric adapter is worth a look.
