Understanding Different Thread Standards
Three primary thread standards are commonly used in garden hoses: Garden Hose Thread (GHT), National Pipe Thread (NPT), and British Standard Pipe (BSP). Each has distinct characteristics and is used in specific applications.
Garden Hose Thread (GHT)
GHT, also known as the American National Standard for Garden Hose (ANSI B1.20.7), is the most commonly used thread type for garden hoses in North America.
Specifications of GHT
- Diameter: 3/4 inch (0.75 inches)
- Pitch: Usually 11.5 threads per inch (TPI)
- Male and Female Ends: The male end features external threads, while the female end has internal threads.
This standard is designed specifically for gardening and is compatible with most American hoses and attachments.
National Pipe Thread (NPT)
NPT is another common threading type, primarily used in plumbing and industrial applications. Although sometimes confused with GHT, they are not interchangeable.
Specifications of NPT
- Diameter: Varies (common sizes include 1/2 inch, 3/4 inch, and 1 inch)
