Product information

Description

The Giacomini R180MY121 is a professional-grade copper pipe fitting designed to provide a secure and durable connection in plumbing and heating systems. This straight fitting features an 18mm connection for copper piping on one side and a 3/4" male thread on the other, facilitating seamless transitions between different types of piping infrastructure. Engineered for reliability, the component is constructed with a high-quality brass finish and includes a dual O-ring sealing system to ensure a leak-proof performance across various applications.

Advantages

This fitting stands out due to its versatile sealing technology, which allows it to be adapted for both water-based plumbing and hydrocarbon-based systems. The inclusion of two distinct O-rings ensures compliance with rigorous safety standards, providing peace of mind regarding seal integrity. Its robust brass construction offers excellent resistance to corrosion and mechanical stress, making it a dependable choice for long-term installations in both residential and commercial environments.

Suitable for

  • Potable water plumbing systems
  • Heating and cooling distribution networks
  • Gas and liquid hydrocarbon transport systems
  • Professional maintenance and repair of copper piping

This fitting may not be suitable for high-pressure industrial steam applications or systems involving highly corrosive chemicals that could degrade the brass or the specific O-ring materials. It is also not intended for use with piping materials other than standard copper pipes.

Key specifications

  • Connection type: 18mm copper pipe to 3/4" male thread
  • Material: Brass
  • Sealing: Dual O-ring system
  • Standard compliance: EN 681-1 for plumbing, EN 549-EN 682 for gas and hydrocarbons
  • Configuration: Straight fitting

To install the fitting, ensure the copper pipe end is clean, deburred, and free of any surface imperfections that could compromise the seal. Insert the pipe into the fitting until it reaches the internal stop, ensuring the O-ring is properly seated. Tighten the threaded connection using appropriate tools, taking care not to overtighten, which could damage the threads or the internal sealing components.

What to consider before purchase

  • Verify the outer diameter of your copper pipe matches the 18mm specification
  • Ensure the 3/4" male thread is compatible with your existing female connection
  • Select the correct O-ring based on whether the system carries water or hydrocarbons
  • Check local building codes for compatibility with your specific piping project
Always inspect the O-rings for any signs of damage or debris before installation to ensure a perfect seal. For gas applications, perform a pressure test according to local safety regulations after the installation is complete.
