What Is Garden Hose Thread?

Garden hose thread (GHT), also referred to as a garden hose internal thread, is a type of hose fitting designed for screwing onto a garden hose and connecting it to a variety of components, such as sprayers, valves, and irrigation systems. Garden hose thread is standardized for the majority of North America and is one of the most commonly used connections for water supply systems.

Historical Context

Garden hose thread is derived from the North American garden hose standard (NH thread) that was introduced in 1925 in the 5th Edition of the American Standard for Hose Coupling Screw Threads. This standard was the result of an effort to standardize garden hose thread among hardware stores, as it was becoming increasingly common to replace the traditionally used leather hawsers (ropes, wires, and chains).

Key Milestones

Since its introduction in 1927, GHT has seen a general acceptance throughout the United States and Canada, becoming the go-to standard for garden hose connections. One of the major milestones of GHT was the introduction of the National Standard for Garden Hose Thread (NST) by the National Fire Protection Association (NFPA) in 1992. This standard was introduced to ensure better compatibility between hoses manufactured and sold in the United States and Canada.

Popular Trends

In recent years, GHT has seen a major increase in its popularity due to its versatility and ease of use. GHT connections are used in numerous applications, including garden hoses, firefighting hoses, and water supply systems. Additionally, GHT connections are becoming increasingly popular in the outdoor irrigation and gardening industry, with users finding GHT to be a reliable and easy-to-use connection for connecting components together.

Potential Pitfalls

Although GHT is a popular and widely-used connection, there are potential pitfalls that users need to be aware of. One such potential pitfall is that the standard GHT connections are not able to be used for hot water applications, as the connection could not withstand the high temperatures associated with these applications. Additionally, users need to be aware that GHT connections are not always compatible with other types of fittings, and should only be used with compatible fittings.

Insights

Overall, garden hose thread (GHT) is a popular and widely-used connection that is becoming increasingly common in both the United States and Canada. GHT is suitable for a variety of applications, including garden hoses, firefighting hoses, and water supply systems, and is easy to use and reliable. Users should be aware of the potential pitfalls of using GHT, such as the fact that GHT connections cannot be used for hot water applications, and should only be used with compatible fittings.
