### Is garden hose thread the same as NPT?

Yes, garden hose thread is not the same as NPT (National Pipe Thread). .

### What is garden hose thread?

Garden hose thread is a type of thread standard used specifically for hoses and hose fittings. It is commonly found on garden hoses, watering tools, and other outdoor equipment. The threads are typically coarse and have a specific shape that allows for a watertight seal when connected. Garden hose thread is measured in terms of the outer diameter of the male thread, rather than the inner diameter like NPT.

### What is NPT?

NPT, or National Pipe Thread, is a standard thread used for sealing pipe connections in North America. NPT threads are tapered and are designed to create a tight seal when mated with another NPT fitting. They are commonly used in plumbing, air systems, and other applications where a leak-proof connection is essential.

### What are the main differences between garden hose thread and NPT?

The main differences between garden hose thread and NPT lie in their design and application. Garden hose thread is typically used for connecting hoses and outdoor equipment, while NPT is used for sealing pipe connections in plumbing and industrial applications. Garden hose thread is coarse and measured by the outer diameter, while NPT is tapered and measured by the inner diameter. Additionally, the pitch and angle of the threads are different between the two standards, making them incompatible with each other.

In conclusion, garden hose thread and NPT are two distinct thread standards with different applications and designs. It is important to use the correct type of thread for each specific use case to ensure a proper and leak-proof connection.
