The TDM Brass 1475E Double Demountable Elbow is a high-quality plumbing fitting engineered for secure and efficient pipe connections in heating and water supply systems. With an 18mm x 3/4 inch configuration, this component provides a reliable 90-degree angle transition, ensuring optimal flow and structural integrity within your piping infrastructure. Crafted from durable brass with a nickel finish, it offers excellent resistance to corrosion and mechanical stress, making it a dependable choice for both residential and commercial applications.

Advantages

The primary benefit of this double demountable elbow is its versatile design, which allows for easy assembly and disassembly without the need for specialized tools or permanent soldering. This feature significantly simplifies maintenance tasks and system modifications, saving time and labor costs. The robust brass construction ensures long-term durability, while the nickel coating provides an additional layer of protection against environmental factors. Its precise engineering guarantees a leak-proof connection, contributing to the overall safety and efficiency of your plumbing network.

Suitable for

• Connecting 18mm pipes to 3/4 inch threaded components
• Plumbing and heating system installations
• Systems requiring frequent maintenance or component access
• Professional piping infrastructure projects

When it may not be suitable

This fitting is not intended for use in high-pressure industrial steam systems or environments where the operating temperature exceeds the specified range of 110°C. It is also not compatible with pipe materials that require specific welding or fusion techniques rather than mechanical compression fittings.

Key specifications

• Material: Brass with nickel finish
• Connection type: Double demountable
• Angle: 90 degrees
• Pipe size: 18mm
• Thread size: 3/4 inch
• Operating temperature range: -20°C to +110°C

How to use

To install the TDM Brass 1475E, ensure the pipe end is cut cleanly and deburred to prevent damage to the internal seals. Insert the pipe into the demountable side of the fitting and tighten the nut securely to create a compression seal. For the threaded side, apply appropriate thread sealant or PTFE tape to the male threads before screwing them into the corresponding female port. Always verify that the connection is tight and perform a pressure test before fully commissioning the system.

What to consider before purchase

• Verify the compatibility of your pipe diameter with the 18mm fitting size
• Ensure the 3/4 inch thread matches your existing valve or equipment port
• Check that the operating temperature of your system stays within the -20°C to +110°C range
• Confirm that the installation space allows for the 90-degree bend radius

Usage recommendations: Regularly inspect the connection points for signs of moisture or loosening, especially after initial installation. Avoid overtightening the nuts, as this can damage the internal sealing components.
