TDM Brass 1470 Double Demountable Elbow 16mm x 1/2 inch with Internal Thread

The TDM Brass 1470 double demountable elbow is a professional-grade plumbing component engineered for reliable pipe connections in water supply and heating systems. Constructed from high-quality brass with a nickel finish, this fitting ensures durability and resistance to corrosion. It features a 90-degree angle design, facilitating smooth directional changes in piping layouts while maintaining a secure, leak-proof seal.

Advantages

This fitting offers exceptional versatility due to its demountable nature, which allows for straightforward installation and future maintenance without the need for specialized permanent bonding tools. The robust brass construction provides excellent thermal stability, making it suitable for a wide range of operating temperatures. Its precise engineering ensures a tight fit, reducing the risk of leaks and enhancing the overall integrity of the plumbing network.

Suitable for

• Residential water supply systems
• Heating circuit installations
• Connecting 16mm pipes to 1/2 inch threaded components
• Maintenance and repair of existing plumbing infrastructure

When it may not be suitable

This fitting is not intended for use in high-pressure industrial steam systems or environments involving highly corrosive chemicals that may degrade the brass or nickel coating. It is also not compatible with pipe materials that require specific welding or solvent-based joining methods.

Key specifications

• Material: Brass with nickel finish
• Connection type: 16mm compression to 1/2 inch internal thread
• Angle: 90 degrees
• Operating temperature range: -20°C to +110°C
• Number of connections: 2

How to use

To install the elbow, ensure the pipe end is cut cleanly and deburred. Insert the pipe into the compression side of the fitting and tighten the nut securely to create a compression seal. On the threaded side, apply appropriate thread sealant or PTFE tape to the male connector before screwing it into the 1/2 inch internal thread of the elbow. Tighten using a suitable wrench, taking care not to overtighten to avoid damaging the threads.

What to consider before purchase

• Verify the outer diameter of your pipe matches the 16mm specification.
• Ensure the threaded connection matches the 1/2 inch standard.
• Check that the operating temperature of your system falls within the -20°C to +110°C range.
• Confirm that the installation space allows for the 90-degree bend.

Usage recommendations

Always inspect the connection for leaks after initial pressurization of the system. If a leak is detected, slightly tighten the compression nut, but avoid excessive force that could deform the fitting.
