Key Questions to Ask When Ordering: The Difference Between GHT and NPT.

When ordering plumbing and irrigation fittings, it is important to ask the right questions. One common question people may have is, "What is the difference between GHT and NPT?" The answer to this question can be crucial in determining the proper fittings to use for a specific application.

GHT, or Garden Hose Thread, is a commonly used thread type for garden hoses and outdoor irrigation systems. NPT, or National Pipe Taper, is a thread type used in plumbing applications. While both thread types may appear similar, they have different functions and cannot be interchanged.

GHT threads have a slightly larger diameter than NPT threads. This means that GHT fittings will not properly screw onto NPT fittings and vice versa. Attempting to use the wrong thread type can result in leaks or even damage to the fittings and pipes.

The difference in thread size also affects the water flow rate. GHT fittings typically have a higher flow rate than NPT fittings, which may be important to consider for certain applications. Additionally, some GHT fittings may be designed for use with low-pressure water, while NPT fittings are typically used for high-pressure applications.

When ordering fittings, it is important to specify the correct thread type to ensure proper function and compatibility with existing systems. It is also important to consider the intended use, water pressure requirements, and flow rate when selecting fittings.

In conclusion, understanding the difference between GHT and NPT threads is crucial for selecting the proper fittings for plumbing and irrigation applications. The difference in thread size and flow rate can greatly affect the performance and functionality of the system. By asking the right questions and specifying the correct thread type, individuals can ensure their systems are running efficiently and effectively.
