Product information

Description

The TDM Brass Lock-Nut Art 121EN 1/2 inch is a professional-grade plumbing component engineered to provide secure and stable threaded connections within piping systems. Constructed from high-quality brass, this lock-nut is designed to withstand the rigors of daily operation in both residential and industrial environments, ensuring that fittings remain tightly fastened even under varying pressure conditions or vibrations.

Advantages

This brass lock-nut offers exceptional durability and resistance to corrosion, which is essential for maintaining the integrity of water supply and heating systems over time. Its precise threading allows for easy installation and a reliable seal, effectively preventing the loosening of components. By utilizing high-quality brass material, the fitting provides a robust solution that minimizes the risk of leaks and mechanical failure in critical plumbing junctions.

Suitable for

  • Securing threaded pipe connections in residential water supply systems
  • Industrial heating and cooling piping installations
  • Preventing loosening of fittings in pressurized plumbing lines
  • General maintenance and repair of threaded plumbing infrastructure

When it may not be suitable

This component is specifically designed for standard 1/2 inch threaded connections and may not be compatible with piping systems using different thread standards or larger diameters. It is also not intended for use in highly aggressive chemical environments where brass may be susceptible to dezincification or specific types of corrosion.

Key specifications

  • Material: High-quality brass
  • Size: 1/2 inch
  • Thread type: Standard plumbing thread
  • Application: Securing threaded connections
  • Resistance: Corrosion-resistant

How to use

To install the TDM Brass Lock-Nut, first ensure that the pipe threads are clean and free of debris. Thread the lock-nut onto the pipe or fitting until it reaches the desired position. Tighten the nut firmly using an appropriate wrench to ensure a secure hold against the mating component. Avoid overtightening, as this may damage the threads or the brass material.

What to consider before purchase

  • Verify that your pipe system requires a 1/2 inch connection size
  • Ensure compatibility with existing threaded fittings
  • Check the material requirements for your specific plumbing environment

Usage recommendations

For optimal performance and to ensure a leak-proof connection, it is recommended to use appropriate thread sealing tape or pipe sealant compound during installation. Regularly inspect the connection for signs of wear or loosening during routine maintenance.
