National Pipe Thread

Okay kiddo, so you know how pipes are used to carry water or gas from one place to another, right? Sometimes these pipes need to be connected to each other using special fittings. National pipe thread, or NPT for short, is a type of threading used on those fittings to create a tight and leak-proof connection between the pipes.

Think of it like two Legos that you want to connect together. They have little bumps and grooves on them that fit perfectly together, so they don't come apart easily. NPT works the same way. The threading on the fittings makes sure that the pipes are screwed on tightly and won't come apart or leak.

But, here's the tricky part. Not all threads are the same size or shape. Kind of like how not all Legos are the same size or shape either. That's why there are different types of NPT threading, like NPTF or NPTM, that are designed for different types of pipes and fittings.

Overall, NPT is just a special type of threading that helps pipes and fittings stay connected and prevent leaks. And just like how Legos need to be connected properly, it's important to use the right type of NPT threading to make sure your pipes are working safely and efficiently.
