Garden Hose Threads What Size

Introduction

Whether your garden hose threads are for a connection to the hose and spigot, a hose fitting, a hose nozzle, or a hose splitter, there is an ideal thread configuration for pipework of all sizes and shapes. Understanding the different size and shape of garden hose threads can help make your next garden hose connection go much more smoothly.

In this article, we'll cover 8-12 topics related to garden hose thread sizes, including:

Summary

1. Introduction to Garden Hose Threads

Garden hose threads, also referred to as hose fittings, are connection points that allow a garden hose to be attached to a faucet, sprinkler, nozzle, or other device. These are necessary for hooking up all related components of a garden hose system. Generally, garden hose threads are conical in shape, preventing from disconnecting when pulled.

2. American National Standard Pipe Thread (NPT)

The American National Standard Pipe Thread (NPT) is the most commonly used thread configuration for garden hoses. This thread is one of two main thread types (the other being the British Standard Pipe (BSP)). It is composed of a series of straight threads with a specified pitch. The threads in NPT are tapered, meaning that the diameter gets smaller as it gets closer to the tip.

3. DIN Standard Threads

DIN Standard Threads are a slightly different type of thread configuration than the American National Standard Pipe Thread. DIN Standard Threads are more commonly used in European countries, and while they look similar to NPT threads, they are not interchangeable. DIN Standard Threads have a series of straight threads with a specified pitch and an additional circular groove near the end, which allows the thread to become tighter or looser.

4. JIS and ISO Metric Threads

JIS and ISO Metric Threads are another type of thread configuration used for garden hoses. These types of threads are generally found on pumps and nozzles. JIS and ISO Metric Threads are much simpler than NPT and DIN Standard threads, with a series of straight threads with a specified pitch.

5. Different Thread Connections Used by Garden Hoses

There are a variety of different thread connections used by garden hoses. These include straight threads, quick connect threads, barbed threads, bayonet threads, and twist-lock threads. Each connection type has its own set of advantages and disadvantages, and it is important to select the one that best meets the requirements of your application.

6. Other Important Factors When Selecting the Right Garden Hose Thread Size

When selecting the right garden hose thread size, it is important to consider a few other factors. One of these is the PSI rating of the garden hose, which indicates how much pressure the hose can handle. It is also important to consider the type of material the hose is made out of as this can affect the type of connection needed.

7. Making Sure That Your Threads Connect Properly

When attaching garden hoses to fittings, it is important to make sure that the threads match up properly to ensure a secure connection. If the threads do not match, it is possible that the connection may leak or even come apart. There are a few easy ways to ensure that the threads on your garden hose and fittings are compatible.

Make sure that the thread configuration is the same. (NPT, DIN, metric, etc.)

Measure the pitch of the threads. (The number of threads per inch)

Compare the major and minor diameter of the threads.

Summary

Garden hose threads are a necessary connection point to attach a garden hose to a faucet, nozzle, or other device. Understanding the different size and shape of garden hose threads is key to making sure that your garden hose system is secure and functioning properly. There are a few different thread types available, including American National Standard Pipe Thread (NPT), DIN Standard Threads, and JIS and ISO Metric Threads, each with its own advantages and disadvantages. It is important to select the thread configuration that best meets the requirements of your application and to make sure that all components of your garden hose system match up properly.
