10 Things You Need to Know About the Difference Between GHT and NPT.

If you're someone who works in the plumbing or irrigation industry, you already know how confusing it can be to keep track of all the different types of fittings that exist. Even more confusing, though, is understanding the difference between GHT and NPT fittings. Here are 10 things you need to know about these two fittings to make your life a little easier.

1. What is GHT? .

GHT stands for "garden hose thread." This is a common type of fitting found on garden hoses or other similar items. It's typically used in low-pressure applications and is often used for attaching things like sprinklers, nozzles, or other garden tools to a garden hose.

2. What is NPT?

NPT stands for "national pipe thread." This is the most common type of fitting used in plumbing and is typically used in higher-pressure applications. It's found on things like water pipes, gas pipes, and other industrial equipment.

3. What's the difference between the two?

The main difference between GHT and NPT is the thread itself. GHT threads are much coarser and have a larger diameter than NPT threads. This makes them easier to attach and detach, but also means they can't withstand as much pressure as NPT threads.

4. Can you use GHT and NPT together?

Generally speaking, no, you cannot. GHT and NPT threads are not compatible with each other, meaning you won't be able to attach them to each other without using some sort of adapter.

5. Are there any exceptions?

There are some exceptions to this rule. For example, some garden hoses come with NPT fittings on one end and GHT fittings on the other, allowing you to connect them to both types of equipment.

6. How do you tell the difference between GHT and NPT threads?

The easiest way to tell the difference between the two is simply by looking at the threads themselves. GHT threads are typically much coarser and have a larger diameter than NPT threads. If you're not sure which type you have, it's best to consult with a professional.

7. Can you convert GHT to NPT or vice versa?

Yes, you can convert between GHT and NPT threads using a variety of adapters and fittings. However, it's important to make sure that the adapter you're using is rated for the pressure you'll be using it at.

8. What should you use GHT fittings for?

GHT fittings are best suited for low-pressure applications like garden hoses or other similar items. They're not designed to withstand high levels of pressure and should not be used in industrial applications.

9. What should you use NPT fittings for?

NPT fittings are designed to withstand higher levels of pressure and are typically used in industrial applications. They're best suited for things like water pipes, gas pipes, and other high-pressure equipment.

10. Can you use GHT or NPT fittings interchangeably?

No, GHT and NPT fittings are not interchangeable. If you try to use one in place of the other, you'll either damage the equipment or create a potentially dangerous situation.

Conclusion.

Understanding the difference between GHT and NPT fittings is essential if you work in the plumbing or irrigation industry.
