GHT vs NPT - Clearing the Confusion.
Have you ever been confused about the difference between GHT and NPT? Don't worry, you're not alone. In this article, we'll explain these two types of threading systems used in plumbing and irrigation systems.
What is GHT?
GHT, or Garden Hose Thread, is a standard size for garden hose connections. It has a diameter of 3/4 inch and a pitch of 11.5 threads per inch. GHT fittings can be found on most garden hoses and irrigation systems.
What is NPT?
NPT, or National Pipe Thread, is a tapered thread system commonly used for plumbing applications. It has a diameter that varies depending on the size of the pipe and a pitch of 8 threads per inch. NPT fittings are used to connect pipes together and can be found in a variety of sizes.
What is the difference between GHT and NPT?
The main difference between GHT and NPT is the way the threads are designed. GHT threads are straight and have a consistent diameter, while NPT threads are tapered and get narrower towards the end of the pipe.
GHT threads are designed to be easily detachable and reattachable, making them ideal for garden hose connections. They also require less sealing material because the threads are more consistent in size.
NPT threads, on the other hand, are designed to create a tight, leak-free seal between two pipes. The tapered threads allow the pipe to be screwed into the fitting with a greater degree of force, resulting in a tighter seal.
Can you use GHT and NPT together?
While it is possible to use GHT and NPT fittings together with the help of an adapter, we do not recommend it. The two threading systems are designed to work with different types of applications and may not provide a secure, leak-free seal.
If you need to connect a garden hose to a plumbing system or vice versa, we recommend using a hose bib adapter with a GHT fitting on one end and an NPT fitting on the other.
Conclusion.
In summary, GHT and NPT are two different threading systems used in plumbing and irrigation systems. GHT is a straight thread system used for garden hose connections, while NPT is a tapered thread system used for plumbing applications.
To avoid confusion and ensure a secure, leak-free connection, we recommend using the appropriate fitting for your application and avoiding the use of adapters unless absolutely necessary.
