What Thread Size Garden Hose

Introduction

I'm sure you've all had the frustration of trying to attach a garden hose to its coupler at some point, only to discover that the threads of one component do not match the threads of the other. But what thread size is a garden hose? This article dives into the answer to this question, with detailed explanations, topics, and illustrations to give you a comprehensive understanding.

The Basic Garden Hose Thread Size

One of the most common thread sizes for garden hoses is known as Garden Hose Threads or GHT, which is also called 3/4-inch GHT. Standard GHT spigots and nozzles usually attach to a 3/4-inch GHT connection (or 3/4-11.5 NH).

Subtypes of Garden Hose Threads

In industries with specially designed connectors, there are several other thread sizes that garden hoses may have. For example, there are Industrial Hose Threads (IHT), National Hose Threads (NHT), and British Standard Pipe Threads (BSPT).

Industrial Hose Threads (IHT)

Industrial Hose Threads (IHT) are one alternative thread size that garden hoses may be standard with. IHT spigots and nozzles are typically 1-inch male or female parts and attach to 1-inch IHT connections (or 1-18 NH).

National Hose Threads (NHT)

Similarly, National Hose Threads (NHT) may also be found in the market, although they can be slightly tougher to find than other standard connection types. The most common NHT size is 11.5-Thread, which is also known as 11.5-NH. NHT spigots and nozzles attach to an 11.5-NH connection.

British Standard Pipe Threads (BSPT)

British Standard Pipe Threads (BSPT) is another thread size seen primarily in the UK, although it can still be found in North America. It is usually available in 3/4-12 or 1-11.5 thread sizes. BSPthreads spigots and nozzles attach to a BSPT connection, with the most common being 3/4-12.

Compatibility Checklist

When shopping for spigots, nozzles, and other garden hose components, use this checklist as a guide to ensure that your parts will work together:

Check part packaging for GHT, IHT, NHT, or BSPT size designation

Match parts with the thread size of the garden hose

Confirm the thread size with a tape measure if necessary

Summary

In summary, what thread size is a garden hose? The standard thread size is known as Garden Hose Threads (GHT), which is commonly 3/4-inch. GHT spigots and nozzles usually attach to a 3/4-11.5 NH connection. Other thread sizes that garden hoses may have include Industrial Hose Threads (IHT), National Hose Threads (NHT), and British Standard Pipe Threads (BSPT). Always use a compatibility checklist to make sure that the components of your garden hose are compatible.
