If you’ve ever dabbled in automotive work, you know that NPT threads can be a bit of a pain when it comes to servicing. They’re solid for a one-time installation, but they don’t really play nice with repeated adjustments. That’s where the HPS AN to NPT Adapter comes in, and let me tell you, it’s a game changer for anyone who likes to tinker under the hood.

This nifty little adapter lets you convert your female NPT threaded ports to an AN style fitting. Why does that matter? Well, AN fittings are designed for easy on-and-off action, so you can swap things out without having to mess with sealants or gaskets each time. Unlike those barbed fittings that can get wrecked after a few uses, this adapter is all about durability and convenience.

Made from 6061 aluminum and finished with a Type II black anodizing, this adapter isn’t just about looks—it’s built to resist corrosion and abrasion too. So whether you’re dealing with fuel, oil, coolant, or even nitrous, you can trust that this adapter can handle it all without breaking a sweat.

Now, let’s get into the specs a bit. You’ve got a 90-degree angle here, which is perfect for tight spaces where a straight fitting just won’t cut it. On one side, you’ll find an AN-4 fitting, while the other side is a 1/4 NPT. It’s a solid combo that really opens up your options for plumbing your setup just the way you want it.

In short, if you’re looking to make your life easier in the garage, this HPS AN to NPT Adapter is worth considering. It’s reliable, versatile, and built to last—what more could you ask for?

  • Side A: AN-4
  • Side B: 1/4 NPT
  • Angle: 90 degrees
  • Material: 6061 aluminum with Type II black anodizing
  • Compatible with: fuel, oil, coolant, alcohol, nitrous, and hydraulic fluid
