Metric threads are a standardized thread type widely used in Europe and many other parts of the world. These threads have a consistent pitch and diameter, making them interchangeable and easy to replace. Metric threads are typically measured in millimeters (e.g., M12, M16) and are commonly used in modern shower hose connections. It is important to verify the metric thread size required by your shower hose and ensure compatibility with the fittings you intend to use.
2. Specific Thread Types
Garden Hose Thread (GHT)
Garden Hose Thread (GHT) is a specific thread type commonly found on outdoor faucets and the connectors of garden hoses. While primarily intended for outdoor use, GHT can also be found in certain shower hose connectors, especially those designed for use with handheld showerheads. It is important to note that GHT threads are not compatible with other standard thread types such as NPT or BSP. Therefore, when dealing with GHT connections, it is essential to ensure you have the correct adapters or connectors to establish a proper connection.
Compression Thread (CT)
Compression threads, also known as compression fittings, offer a reliable and watertight connection. These threads are commonly used in plumbing systems, including shower hoses. A compression thread connection consists of a compression nut and a ferrule that compresses onto the pipe or hose, creating a seal. When dealing with compression thread connections for shower hoses, it is important to ensure proper sizing and compatibility between the compression fittings and the hose itself.
Quick Disconnect Thread (QDT)
Quick Disconnect Thread (QDT) is a thread type designed for easy and quick connection and disconnection of components. QDT allows for fast and tool-free installation and removal of shower hoses, making it convenient for those who frequently switch between handheld and fixed showerheads.

Using the appropriate thread sealant is crucial to guarantee the longevity and performance of your shower hose connections.
Types of Thread Sealants
There are various types of thread sealants available, including thread sealant tapes and pipe joint compounds. Teflon tape, a popular thread sealant option, is a thin film made of polytetrafluoroethylene (PTFE). It is applied to the threaded male end and provides lubrication while allowing for a secure and leak-free connection. Pipe joint compounds, such as paste or liquid sealants, offer a more robust sealing solution and can be used for more demanding applications. It is important to select the right type of thread sealant based on the compatibility with the thread material and the intended use.
5. Installation Methods
Hand-Tightening
Hand-tightening is the most basic method of installing a shower hose connection. It involves simply turning the threaded fittings by hand until they are snug and secure. Hand-tightening is suitable for most standard shower hose connections where the thread type and sizing are appropriately matched. However, it is essential not to overtighten the connection as it can lead to damage or cross-threading.
Using Wrenches
In cases where a firm and secure connection is required, such as with compression fittings or stubborn thread types, the use of wrenches may be necessary. Care must be taken when using wrenches to avoid over-tightening, which can strip or damage the threads. Always use the appropriate size and type of wrench, such as an adjustable wrench or pipe wrench, and exercise caution to achieve the right level of tightness without causing any harm to the threads or fittings.
Using Teflon Tape
Teflon tape is an effective and commonly used method of sealing threaded connections. To use Teflon tape, wrap it around the male threads in a clockwise direction until the threads are completely covered. The tape helps fill any gaps or imperfections, creating a watertight seal. It is important to avoid excessive overlapping or stretching of the tape, as this can lead to poor sealing or difficulty in tightening the connection. Teflon tape should be applied carefully, ensuring that it does not obstruct or interfere with the threading process.
