## Long description

The TDM Brass 3/4 inch x 20 mm threaded extender is a high-quality plumbing component designed to provide a secure and precise extension for various pipe connections and valves. Crafted from durable brass, this fitting is engineered to withstand the rigors of both residential and industrial piping systems, ensuring a reliable and leak-proof assembly. Its dual-threaded design, featuring both internal and external threads, allows for versatile integration into existing plumbing and heating infrastructures.
Advantages
The primary advantage of this brass extender lies in its robust material composition, which offers excellent resistance to corrosion and mechanical wear over time. The precision-machined threads ensure a tight fit, minimizing the risk of leaks and reducing the need for frequent maintenance. Its compact 20 mm length makes it an ideal solution for tight spaces where standard fittings might be too bulky, providing the necessary reach without compromising the integrity of the connection.
Suitable for
Extending pipe connections in residential plumbing systems
Connecting valves to existing pipework in heating installations
Adapting thread sizes or lengths in industrial fluid transport lines
Repairing or modifying existing water supply configurations
When it may not be suitable
This extender is not intended for use in high-pressure steam systems or environments involving highly corrosive chemicals that may degrade brass. It is also not suitable for applications requiring non-metallic materials or specific food-grade certifications not covered by standard brass fittings.
Key specifications
Material: Brass
Connection size: 3/4 inch
Length: 20 mm
Thread type: Internal/External
How to use
To install the extender, ensure that the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or a liquid pipe sealant, to the external threads to ensure a watertight connection. Screw the extender onto the existing pipe or valve by hand, then tighten it firmly using a suitable wrench. Avoid overtightening, as this may damage the threads or the fitting itself. Once installed, pressurize the system slowly to check for any signs of leakage.
What to consider before purchase
Verify the thread size of your existing pipes to ensure compatibility with the 3/4 inch specification.
Check the available clearance to confirm that the 20 mm length is sufficient for your specific installation needs.
Ensure that the operating temperature and pressure of your system fall within the standard limits for brass fittings.
Usage recommendations
For optimal performance and longevity, always use compatible tools during installation and ensure that the threads are properly aligned before tightening to prevent cross-threading.
