Common Garden Hose Thread Types
Garden hoses connect to faucets and sprinklers using threaded fittings. These threads come in several common types. Knowing these types helps you find the right hose or adapter.
Thread types vary by region and application. Some threads fit standard garden hoses, while others are used in industrial or international settings.
Garden Hose Thread (ght)
Garden Hose Thread (GHT) is the most common thread type in the United States. It is used for most garden hoses and outdoor water connections.
The GHT has a 3/4 inch diameter and 11.5 threads per inch. It features a straight thread design with a rubber washer to seal the connection.
- 3/4 inch diameter
- 11.5 threads per inch
- Straight threads with a sealing washer
- Used mainly in US residential garden hoses
National Hose (nh) Thread
National Hose (NH) thread is a large, heavy-duty thread used in fire hoses and industrial water lines. It is not common for home garden hoses.
NH threads are 1.5 inch or larger in diameter. They have a straight thread form and use a gasket for sealing. These threads are strong and made for high pressure.
- Diameter ranges from 1.5 inches and above
- Straight threads with gasket seal
- Used in fire hoses and industrial hoses
- Not typical for garden hoses
British Standard Pipe (bsp) Thread
British Standard Pipe (BSP) thread is common in the UK and many other countries. It is often used for garden hoses outside the US.
BSP threads come in two types: parallel (BSPP) and tapered (BSPT). The most common garden hose size is 3/4 inch BSP. BSP threads seal by tightening the thread itself or with an additional washer.
- Available as parallel (BSPP) or tapered (BSPT)
- Common size is 3/4 inch diameter
- Used widely outside the US
- Seals by thread fit or washer
Metric Thread Variants
Metric thread variants are common in Europe and Asia. These threads use metric measurements for diameter and pitch.
Metric threads can have different pitches and diameters. They may not fit US or British hose fittings without an adapter.
- Measured in millimeters (diameter and pitch)
- Common sizes include M22x1.5 and M24x1.5
- Often used in European garden hoses
- Adapters may be needed for compatibility

Thread Size And Pitch
Garden hoses use threaded ends to connect to faucets and accessories. The thread size and pitch are important for a proper fit.
Understanding these terms helps you choose the right hose and avoid leaks or damage.
Standard Diameter Measurements
The most common garden hose thread size is 3/4 inch in diameter. This size fits most outdoor faucets and hose connectors.
Other sizes like 1/2 inch or 5/8 inch exist but are less common for threads.
- 3/4 inch (19.05 mm) is standard for garden hoses
- 1/2 inch and 5/8 inch diameters are usually hose inner sizes, not thread sizes
- Thread diameter refers to the outer size of the threaded part
Thread Pitch Differences
Thread pitch means the distance between threads on the hose end. It affects how tightly the hose connects.
Garden hoses usually have a thread pitch of 11.5 threads per inch (TPI). This is called GHT or Garden Hose Thread.
- 11.5 TPI is standard for garden hose threads
- Other threads like NPT have different pitches and are not compatible
- Thread pitch ensures a secure and leak-free connection
How Size Affects Compatibility
Matching thread size and pitch is key to hose compatibility. Using the wrong size causes leaks or damage.
Always check the thread diameter and pitch before buying connectors or accessories.
- Correct size ensures tight and leak-proof connections
- Wrong size may not fit or can damage threads
- Standard GHT threads work with most garden hoses and faucets
Thread Material And Coating
Garden hoses come with different types of threads. These threads are crucial for connecting hoses to faucets and other equipment. The material and coating of these threads affect their durability and performance.
Understanding the materials used in garden hose threads helps in choosing the right hose for your needs. Let’s explore some common thread materials and coatings.
Brass Threads
Brass threads are known for their strength. They resist damage from physical impacts and extreme temperatures. Brass is a common choice for garden hose fittings.
- Durable and long-lasting
- Resistant to rust
- Handles high water pressure
Plastic Threads
Plastic threads are lightweight and affordable. They are suitable for light-duty garden hoses. While not as durable as brass, they are corrosion-resistant.
| Material | Durability | Weight |
| Brass | High | Heavy |
| Plastic | Medium | Light |
Corrosion Resistant Coatings
Some threads have special coatings to prevent corrosion. These coatings extend the life of the hose. They are ideal for areas with high humidity.

Identifying Your Hose Thread
Garden hoses come with different types of threads. Knowing your hose thread helps you find the right connectors and fittings. This guide shows simple ways to identify the thread on your garden hose.
You can check the thread by looking closely, using special tools, or measuring the thread size. Each method gives you clues about your hose thread type.
Visual Inspection Tips
Look at the hose end carefully. Check if the threads are coarse or fine. Also, note if the threads are on the inside or outside of the hose fitting.
- External threads usually mean a male hose thread.
- Internal threads usually mean a female hose thread.
- Coarse threads are often garden hose threads (GHT).
- Fine threads might be other types like NPT or BSP.
Using Thread Gauges
Thread gauges help measure the pitch and size of threads. Use a thread gauge tool to match your hose thread with standard patterns.
- Place the gauge on the threads.
- Find the gauge that fits perfectly between the threads.
- Note the pitch number from the gauge.
- Compare this pitch to common hose thread types.
Measuring Diameter And Pitch
Use a ruler or caliper to measure the outside diameter of the hose fitting. Then count the number of threads per inch (TPI) to find the pitch.
| Measurement | How to Measure | Common Size |
| Diameter | Measure across the threads | Usually 3/4 inch for garden hoses |
| Pitch | Count threads per inch | Typically 11.5 TPI for GHT |
Matching Threads For Accessories
Garden hoses use specific thread types to connect accessories. Matching these threads is key for proper fit.
Using the right thread size helps avoid leaks and makes attaching parts easier.
Fittings And Connectors
Garden hoses usually have either male or female threads. Most common thread sizes are 3/4 inch.
- GHT (Garden Hose Thread) is standard in the U.S.
- Thread types include BSP and NPT in some regions.
- Connectors must match the hose thread type to fit correctly.
Adapters And Converters
Adapters help connect hoses to different thread types. They convert male threads to female or vice versa.
| Adapter Type | From Thread | To Thread |
| GHT to NPT | Garden Hose Thread | National Pipe Thread |
| BSP to GHT | British Standard Pipe | Garden Hose Thread |
| Quick Connect | Standard Thread | Snap Fit |
Ensuring Leak-free Connections
Proper thread matching helps prevent leaks. Use thread tape or washers for a tight seal.
