TDM Brass Lock-Nut 3/4 inch

The TDM Brass 3/4 inch lock-nut is a robust plumbing component engineered to provide a secure and stable connection within various piping systems. Constructed from high-quality brass with a nickel finish, this lock-nut offers excellent resistance to corrosion and mechanical wear, ensuring long-term reliability in both water supply and heating installations. Its precise threading is designed to lock fittings firmly in place, preventing accidental loosening due to vibrations or thermal expansion.

Advantages

The primary benefit of this lock-nut is its durable brass construction, which provides superior strength compared to plastic or lower-grade metal alternatives. The nickel coating adds an extra layer of protection against oxidation, making it suitable for environments where moisture is present. Its standard 3/4-inch internal thread ensures compatibility with a wide range of plumbing fixtures, allowing for a tight, leak-resistant seal that maintains the integrity of the entire piping network.

Suitable for

• Securing threaded connections in residential water supply systems
• Locking fittings in place within heating and radiator installations
• Industrial piping applications requiring vibration-resistant joints
• Connecting various 3/4-inch threaded plumbing components

When it may not be suitable

This lock-nut is not intended for use with piping systems that exceed the specified temperature range of -20 to +120°C, as extreme conditions may compromise the material integrity. It is also not suitable for applications involving highly aggressive chemical substances that could react with the brass or nickel plating.

Key specifications

• Material: Brass with nickel finish
• Connection type: 3/4 inch internal thread
• Operating temperature range: -20°C to +120°C
• Application: Plumbing and heating systems

How to use

To install the TDM Brass lock-nut, first ensure that the threaded pipe or fitting is clean and free of debris. Thread the lock-nut onto the pipe until it reaches the desired position against the mating fitting. Use an appropriate wrench to tighten the nut firmly, ensuring that the connection is secure without over-tightening, which could potentially damage the threads. Verify that the seal is tight and check for any signs of leakage once the system is pressurized.

What to consider before purchase

• Verify that your piping system utilizes a 3/4-inch thread size
• Ensure the operating environment stays within the -20 to +120°C temperature range
• Check for compatibility with other materials in your piping system to prevent galvanic corrosion

Usage recommendations

Regularly inspect the connection points in your plumbing system for signs of wear or loosening, especially in high-vibration environments, to ensure the lock-nut remains properly tightened over time.
