TDM Brass 1440E 20x20 Double Demountable Threaded Joint

The TDM Brass 1440E 20x20 double demountable threaded joint is a high-performance plumbing component engineered for secure and efficient pipeline connections. Crafted from durable brass, this fitting provides excellent resistance to corrosion and mechanical stress, making it a reliable choice for both residential and commercial plumbing and heating systems. Its precision-engineered threads ensure a tight, leak-proof seal, while the double demountable design facilitates straightforward installation and future maintenance.

Advantages

The primary benefit of this brass fitting is its robust construction, which guarantees long-term durability and consistent performance under varying pressure conditions. The double demountable feature significantly simplifies the assembly and disassembly process, allowing technicians to perform repairs or system modifications without the need for cutting or permanent pipe alteration. Furthermore, the high-quality brass material offers superior thermal stability and compatibility with standard piping materials, ensuring a professional-grade connection that minimizes the risk of leaks.

Suitable for

• Residential water supply systems
• Heating and radiator installations
• Maintenance and repair of existing threaded pipelines
• Professional plumbing projects requiring demountable connections

When it may not be suitable

This fitting is not intended for use in high-pressure industrial steam lines or systems involving highly corrosive chemicals that may degrade brass over time. It is also not suitable for applications where the pipe diameter does not match the 20x20 mm specification.

Key specifications

• Material: High-quality brass
• Connection type: Double demountable threaded joint
• Size: 20x20 mm
• Application: Plumbing and heating systems

How to use

To install the TDM Brass 1440E 20x20, ensure that the pipe ends are clean, deburred, and cut square. Apply appropriate thread sealant or PTFE tape to the male threads if required by local plumbing standards. Align the fitting with the pipe ends and tighten the nuts manually, followed by a final adjustment using a suitable wrench to ensure a secure, leak-proof connection. Avoid overtightening, as this may damage the threads or the internal sealing surfaces.

What to consider before purchase

• Verify that the 20x20 mm size is compatible with your existing pipe diameter.
• Ensure the system pressure and temperature ratings are within the operational limits of brass fittings.
• Check if additional sealing materials are required for your specific installation environment.

Usage recommendations

Regularly inspect the connection points for signs of moisture or leaks, especially after initial installation or system maintenance. Ensure that the fitting is not subjected to excessive mechanical vibration or structural load.
