    • What Size Are Garden Hose Threads?

    Confusion around garden hose threads (commonly referred to as hose threads', hose fittings', or hose connectors') is a common problem. Before attempting to select the size and type of hose to purchase, it's important to familiarize yourself with the basics of this garden essential. This article will provide an introduction to hose threads, their purpose, and how to select the correct size for your project.

    Garden hose threads, also known as tapered threads, are straight threads with a slightly tapered design. This type of thread is used in the engineering and plumbing industries. When two threads are joined together, the taper of the threads will create a seal, and prevent leaking. This design also allows any garden hose to be connected to a variety of attachments.

    When measuring hose threads, it's important to note that the measurements designated by the National Pipe Thread (NPT) standard do not necessarily refer to the outside diameter of the thread. Instead, they are designated lengths of threads along the length of the pipe. The typical male and female thread diameters and pitches are:

    1/2 inch x 11.5 TPI (threads per inch) for the male thread and

    1/2 inch x 14 TPI for the female thread.

    There are two different types of threads commonly used on garden hoses, with the primary difference being the type of thread. The most common type is male and female National Pipe Thread (NPT) threads which are made to the dimensions described above. The second type is garden hose thread (GHT) which has the same size external diameter and pitch (threads per inch), but has a slightly different internal taper to create a better seal.

    In addition to the threads found on the hose itself, it's important to understand the threads found on the connectors that attach to the hose. Most garden hose fittings are made with either a male or female GHT thread, while the interior escalates to a National Pipe Thread (NPT) connection. The male side of a connector will usually be an NPT thread, while the female side is usually a GHT thread.

    In order to connect a hose connector to a garden hose, it's important to select the correct size and type of threading. It's important to match the type of thread on the connector with the type of thread found on the hose, usually either GHT or NPT. When selecting the size of the thread, it's important to select the correct diameter and pitch of the thread.

    When selecting the right size and type of thread for your garden hose, it's important to take the following steps:

    The type of thread found on the connector should be either GHT (Garden Hose Thread) or NPT (National Pipe Thread).

    Use a ruler or thread gauge to measure the thread inside diameter and pitch of the thread. Be sure to note whether the thread is imperial (inches) or metric (millimeters).

    Once you know the thread size and pitch of the connector, you can select a garden hose thread that matches the same size and pitch.

    Garden hose threads can be confusing, but they are essential for connecting hoses to fittings and other pipes. Before making any purchase, be sure to identify the size and type of thread found on the connector, then measure the thread size and pitch to ensure you select the right size and type of thread for your project.

    This article provided an introduction to the basics of garden hose threads and how to select the correct size and type of thread for your project. With this knowledge, you can now confidently choose the perfect thread size for your next garden project.
