What size is garden hose thread in MM?
The US standard was defined by NFPA 1963, “Standard for Fire Hose Connections”, then later by ANSI-ASME B1. 20.7, which specifies 1+1⁄16 inches (27 mm) diameter straight (non-tapered) thread with a pitch of 11.5 threads per inch (TPI).
Garden hose threads are primarily measured using imperial units rather than millimeters (MM). The most common thread sizes for garden hoses are based on the United States standard thread (NH or NST) and the British standard pipe thread (BSP). These thread standards use measurements in inches rather than millimeters.
For United States standard thread (NH or NST), the thread size refers to the inside diameter (ID) of the hose. The most common sizes are 3/4 inch (19.05 mm) and 5/8 inch (15.88 mm).
In the case of British standard pipe thread (BSP), the thread size refers to the outside diameter (OD) of the threaded part. The most common size for BSP thread is 3/4 inch (19.05 mm).
It’s important to note that while some fittings and adapters may provide metric conversions, garden hose threads are traditionally labeled and referred to using the imperial measurements.
What type of thread is a garden hose fitting?
Garden Hose Thread (GHT) comes male (MGHT) and female (FGHT). It’s important to note that GHT is different from NPT. Garden hose connections are not compatible with NPT even though both are threaded. Where a water hose fitting is required, this would be the connection to look for.
Garden hose fittings typically use a specific type of thread known as a “Garden Hose Thread” (GHT). The Garden Hose Thread is a standard thread size used specifically for garden hoses and their attachments.
The Garden Hose Thread (GHT) follows two primary standards: the United States standard thread (NH or NST) and the British standard pipe thread (BSP). The United States standard thread is commonly used in North America, while the British standard pipe thread is more prevalent in the United Kingdom and other parts of the world.
The United States standard thread (NH or NST) typically features a thread pitch of 11.5 threads per inch (TPI) and an inside diameter (ID) of approximately 1 inch (25.4 mm). The British standard pipe thread (BSP) used for garden hoses usually has a thread pitch of 14 threads per inch (TPI) and an outside diameter (OD) of approximately 1 inch (25.4 mm).
It’s important to note that the Garden Hose Thread (GHT) is not compatible with standard pipe threads used in plumbing applications. If you need to connect your garden hose to other plumbing fittings or devices, you may require adapters or specialized fittings designed to bridge the gap between different thread types.
What is standard garden hose thread size?
The diameter of threaded fitting inside a hose is referred to as the thread size. Hose diameters range from 3/8 inch, 1/2 inch and 3/4 inch. The bigger the diameter, the more water is delivered. The most common garden hose thread size is 3/4 inch.
The standard garden hose thread size is commonly referred to as 3/4 inch (19.05 mm) in the United States. This size is based on the United States standard thread (NH or NST) and is widely used for garden hoses and their fittings.
The 3/4 inch garden hose thread size refers to the inside diameter (ID) of the hose. It is the most common and widely available size for garden hoses, allowing for a good balance between water flow and pressure.
It’s important to note that the 3/4 inch garden hose thread size is not an exact measurement in millimeters (mm). The approximate conversion of 3/4 inch is about 19.05 mm.
However, it’s worth mentioning that other countries or regions may have different standard thread sizes for garden hoses. For example, in the United Kingdom, the standard thread size for garden hoses is typically referred to as 1/2 inch, which is roughly 12.7 mm in diameter.
What are popular garden hose sizes?
Garden hoses are available in ½’, 5/8′, and ¾’ sizes. 5/8 inches is the most commonly recommended size for homeowners for everyday lawn and garden watering.
Popular garden hose sizes generally vary depending on the region and specific needs of users. However, there are a few common garden hose sizes that are widely used:
3/4 Inch (19.05 mm): This is the most popular and standard garden hose size in the United States. It strikes a balance between water flow and pressure, making it suitable for a wide range of watering tasks in residential and commercial settings.
5/8 Inch (15.88 mm): Another common garden hose size in the United States, the 5/8 inch hose is slightly smaller in diameter than the 3/4 inch hose. It is commonly used for general household watering needs and is often lighter and more flexible than larger diameter hoses.
1/2 Inch (12.7 mm): In some regions, such as the United Kingdom, the 1/2 inch garden hose is prevalent. It is suitable for smaller gardens and lighter watering tasks.
These three sizes mentioned above represent the most popular and widely available options for garden hoses. However, other sizes may exist depending on specific applications, such as industrial or commercial use.
When selecting a garden hose, it’s essential to consider factors such as water pressure, hose length, and the specific requirements of your gardening or watering needs to ensure optimal performance.
What are the common thread standards used for garden hoses?
The common thread standards used for garden hoses are the United States standard thread (NH or NST) and the British standard pipe thread (BSP).
United States Standard Thread (NH or NST): This thread standard is widely used in North America. The NH stands for National Hose and NST stands for National Standard Thread. It typically features a thread pitch of 11.5 threads per inch (TPI) and an inside diameter (ID) of approximately 1 inch (25.4 mm). The NH/NST thread is compatible with most standard garden hose fittings and nozzles in the United States.
British Standard Pipe Thread (BSP): This thread standard is commonly used in the United Kingdom and other parts of the world. The most common BSP size for garden hoses is 3/4 inch, which has a thread pitch of 14 threads per inch (TPI) and an outside diameter (OD) of approximately 1 inch (25.4 mm).
It’s important to note that these two thread standards are not interchangeable. Adapters or specialized fittings may be needed to connect garden hoses with different thread standards. When purchasing fittings or attachments for your garden hose, ensure compatibility with the appropriate thread standard for your region.
How do I determine the correct thread size for my garden hose?
To determine the correct thread size for your garden hose, you can follow these steps:
Measure the Inside Diameter (ID): Using a ruler or tape measure, measure the inside diameter of the hose’s threaded portion. This is the part of the hose where fittings are attached.
Count the Threads per Inch (TPI): Next, count the number of threads within a one-inch span. Use a thread pitch gauge or simply mark a point and count the threads manually.
Compare Measurements: Once you have the inside diameter and thread pitch, compare them to standard thread sizes. Common garden hose thread sizes are 3/4 inch (19.05 mm) for United States standard thread (NH or NST) and 3/4 inch (19.05 mm) for British standard pipe thread (BSP).
Consult Manufacturer or Supplier: If you’re still uncertain about the thread size, consult the manufacturer of the hose or a knowledgeable supplier who can provide guidance based on the make and model of your hose.
Alternatively, you can take your garden hose to a local hardware store or plumbing supply shop and ask for assistance in determining the correct thread size. They may have specialized tools or expertise to help identify the thread size accurately.
