TDM Brass 1435E Demountable Threaded Bit 18mm x 1/2 inch

The TDM Brass 1435E demountable threaded bit is a precision-engineered component designed for creating secure and reliable connections in plumbing and heating systems. With an 18mm pipe connection and a 1/2-inch threaded interface, this fitting is built to maintain system integrity under varying pressure conditions. The robust brass construction, enhanced with a nickel finish, ensures long-term durability and resistance to the corrosive effects often found in water supply networks.

Advantages

This threaded bit offers exceptional mechanical strength and resistance to thermal expansion, which is critical for maintaining leak-proof joints in demanding environments. The demountable design allows for easier maintenance and system adjustments without the need for permanent soldering or complex tools. Its high-quality material composition provides reliable performance across a wide temperature range, ensuring that the connection remains stable even during significant thermal fluctuations in heating or hot water circuits.

Suitable for

• Residential water supply systems
• Commercial heating installations
• Maintenance and repair of existing pipe networks
• Connecting copper or composite pipes to threaded valves and fittings

This component may not be suitable for high-pressure industrial steam applications or systems carrying highly aggressive chemical substances that could degrade the brass or nickel plating. It is also not intended for use in gas distribution lines unless explicitly certified for such purposes.

Key specifications

• Connection size: 18mm pipe to 1/2 inch thread
• Material: Brass with nickel coating
• Operating temperature range: -20°C to +110°C
• Connection count: 2

To install the TDM Brass 1435E, ensure that the pipe end is cut cleanly and deburred to prevent damage to the internal sealing elements. Insert the pipe into the fitting and tighten the threaded connection using appropriate plumbing tools, ensuring that the seal is properly seated. Avoid overtightening, as this may damage the threads or the sealing surface.

What to consider before purchase

• Verify the outer diameter of your existing piping to ensure compatibility with the 18mm connection.
• Check the thread type of your existing valve or fitting to ensure it matches the 1/2 inch specification.
• Ensure the operating temperature of your system falls within the -20°C to +110°C range.

Always use appropriate thread sealing tape or liquid sealant when connecting the threaded side to ensure a watertight seal, and inspect the connection for leaks after the system has been pressurized.
