AN vs NPT: What's The Difference Anyway?

What's the real scoop between AN and NPT? Well, buckle up gearheads, we're about to dive into the nitty-gritty of automotive fittings!

Don't Lose Your Thread

First off, let's get our terms straight. AN, or Army-Navy fittings, are your go-to for a reliable, leak-free connection. Ideal for high-pressure situations, they're the Corvette of the fitting world - sleek, reliable, and all about performance.

On the other hand, NPT, or National Pipe Thread fittings, are the workhorses. They're like your dependable Chevy SS - they may not be flashy, but boy, they get the job done. NPT fittings are designed for general use and are great for low-pressure applications.

It's All About The Angle

One of the main differences between AN and NPT is the thread angle. AN fittings come with a 37-degree flare, making them the Usain Bolt of fittings, sprinting towards a tight seal. NPT fittings, however, have a 60-degree thread angle, ideal for general plumbing. It’s like comparing a Camaro to a family-friendly minivan. Both will get you from point A to point B, but one does it with more style and speed.

Mixing AN and NPT: A Recipe for Disaster?

While some hot-rodders may get a wild idea to mix AN and NPT fittings, it’s best to keep them in their respective lanes. Like trying to cram a LS9 engine into a Pontiac G8 GT, it's not going to end well!
