Product information

Description

The TDM Brass Extender 3/4" x 20 mm is a precision-engineered threaded fitting designed to facilitate the extension of pipe connections in plumbing and heating systems. Crafted from high-quality brass, this component offers exceptional durability and resistance to corrosion, ensuring a long service life in demanding hydraulic environments. Its standardized dimensions allow for seamless integration into existing piping networks, providing a secure and reliable connection that maintains system integrity.

Advantages

This brass extender provides a robust solution for adjusting pipe lengths without the need for complex modifications. The high-grade metal construction ensures excellent thermal stability and mechanical strength, making it suitable for both hot and cold water applications. Its precise threading guarantees a tight, leak-proof seal, which is essential for maintaining pressure and preventing water loss in residential or commercial plumbing installations.

Suitable for

  • Extending pipe connections in water supply systems
  • Connecting components in heating and radiator circuits
  • Adapting threaded fittings in hydraulic installations
  • Repairing or modifying existing plumbing configurations

When it may not be suitable

This fitting is not intended for use in high-pressure industrial steam systems or environments where the brass material may be subject to aggressive chemical exposure. It should not be used in applications requiring materials other than brass, such as specific food-grade or highly acidic fluid transport systems.

Key specifications

  • Material: Brass
  • Connection type: Male-Female threaded
  • Diameter: 3/4 inch
  • Length: 20 mm

How to use

To install the TDM Brass Extender, ensure the pipe ends are clean and free of debris. Apply an appropriate thread sealant, such as PTFE tape or liquid sealant, to the male threads to ensure a watertight connection. Thread the extender onto the existing pipe or fitting by hand, then tighten it securely using a suitable wrench. Avoid over-tightening to prevent damage to 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 that the 3/4 inch thread size matches your existing piping
  • Ensure the 20 mm length is sufficient for your specific extension requirements
  • Check compatibility with the pipe material to prevent galvanic corrosion
  • Confirm that the operating pressure and temperature are within the limits of brass fittings

Usage recommendations

Regularly inspect the connection for signs of moisture or corrosion during routine system maintenance. If the fitting is removed for repairs, it is recommended to replace the thread sealant before reinstallation to maintain a reliable seal.
