## Long description

The TDM Brass 3/4" x 30 mm threaded extender is a professional-grade plumbing fitting engineered to provide reliable length adjustments in pipeline systems. Constructed from high-quality brass, this component is designed to bridge the gap between connections where standard fittings may fall short. It features a combination of internal and external threads, allowing for seamless integration into existing water supply or heating infrastructure while maintaining structural integrity.
Advantages
This brass extender offers exceptional durability and longevity due to its robust material composition, which effectively resists corrosion and withstands significant temperature fluctuations. The precision-machined threads ensure a tight, secure fit that minimizes the risk of leaks, providing peace of mind in both residential and commercial plumbing applications. Its compact design allows for easy installation in confined spaces, making it a versatile solution for complex piping configurations.
Suitable for
Extending water supply lines in residential plumbing
Connecting components in heating and radiator systems
Adapting thread types in industrial pipeline maintenance
Adjusting pipe lengths in tight installation areas
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 over time. It should also not be used in applications where the pipe diameter or thread standard differs from the specified 3/4 inch size.
Key specifications
Material: Brass
Thread size: 3/4 inch
Extension length: 30 mm
Connection type: Internal/External thread
How to use
To install the extender, ensure the pipeline is depressurized and drained. Clean the existing threads on both the pipe and the fitting to remove any debris or old sealant. Apply appropriate thread sealing tape or pipe compound to the external threads of the extender. Screw the extender onto the existing pipe connection and tighten it using a suitable wrench, ensuring it is secure but not overtightened to avoid damaging the brass threads. Once installed, connect the secondary component to the internal thread side of the extender and perform a pressure test to verify that the connection is leak-free.
What to consider before purchase
Verify that the 3/4 inch thread size matches your existing plumbing infrastructure.
Ensure there is sufficient clearance for the 30 mm length extension.
Check compatibility with the fluid type and operating temperature of your system.
Confirm that you have the necessary tools for proper installation.
Usage recommendations
Regularly inspect the connection point for any signs of moisture or corrosion during routine maintenance checks to ensure the long-term reliability of your plumbing system.
