Straight Union MI 28mm - 1"

The EXF9-S28x1MI Straight Union MI 28mm - 1" press fitting is a robust plumbing component designed to connect a 28mm pipe to a 1-inch male-threaded (MI) component. It utilizes press-fit technology on the pipe side and features a 1-inch male threaded (MI) connection on the other side. This fitting is widely used in plumbing, heating, and HVAC systems where a secure and reliable connection is needed between larger diameter pipes and male-threaded components.

Key Features and Description:

1. Material:

   • The EXF9-S28x1MI is typically made from high-quality brass or stainless steel, both of which are known for their excellent resistance to corrosion, durability, and ability to handle high pressure and temperatures.
   • Brass is commonly used for plumbing fittings due to its strength and resistance to corrosion, ensuring long-term performance in systems that deal with water and heating.
   • Stainless steel may be used in more demanding applications where superior corrosion resistance is necessary, such as in systems dealing with aggressive water or chemical conditions.

2. Design and Configuration:

   • 28mm Pipe Connection: One side of the fitting is designed to connect to a 28mm pipe, a size often used in larger residential plumbing systems and heating circuits, especially for mains water supply or central heating systems.
   • 1" Male Threaded (MI) Connection: The other side features a 1-inch male threaded (MI) connection, intended for use with 1-inch female threaded components such as valves, pumps, manifolds, or other threaded fixtures.
   • Straight Union Design: As a straight union, this fitting connects two components in a direct, linear fashion. It enables the transition from a 28mm pipe to a 1-inch male-threaded connection, offering a reliable solution when connecting two different types of fittings or components.

3. Press-Fit Technology:

   • The EXF9-S28x1MI fitting utilizes press-fit technology for the pipe connection. When installed, the fitting is pressed onto the 28mm pipe using a press tool, creating a permanent, secure, and leak-proof seal without the need for soldering or threading.
   • The press-fit connection eliminates the potential for leaks that can occur in traditional fittings that rely on mechanical threads or heat-based methods like soldering.
   • Once the fitting is pressed, the seal is permanent and able to withstand high pressure and temperature fluctuations, ensuring a long-lasting connection.

4. Applications:

   • The EXF9-S28x1MI press fitting is used in a variety of applications where 28mm pipes need to be connected to 1-inch male-threaded components. These applications include:
     • Central Heating Systems: Connecting 28mm pipes to 1-inch male-threaded valves, pumps, radiators, or manifolds.
     • Underfloor Heating (UFH): Connecting 28mm pipes to 1-inch male-threaded components like manifolds, pumps, or mixing valves.
     • Water Supply Systems: Linking 28mm pipes to 1-inch male-threaded components such as taps, faucets, and filtration systems.
     • Industrial and Commercial Plumbing: Common in large-scale systems where 28mm piping needs to connect to components that require 1-inch male-threaded connections.

5. Advantages:

   • Quick Installation: Press-fit technology significantly speeds up the installation process compared to traditional methods like soldering or threading. This makes it ideal for projects that require efficiency and reliability.
   • Permanent, Leak-Proof Seal: Once the fitting is pressed onto the pipe, it forms a permanent, leak-proof seal that ensures a secure connection that will not loosen over time.
   • No Heat or Soldering Required: The installation process is cleaner and safer because it does not require open flames or soldering. This reduces the risk of fire hazards and eliminates the mess and fumes associated with traditional soldering methods.
   • Corrosion Resistance: The materials used in the EXF9-S28x1MI fitting, such as brass or stainless steel, provide excellent resistance to corrosion, ensuring the longevity of the connection even in harsh water conditions.
   • Cleaner and Safer Installation: Since no flux, solder, or open flames are required, the installation is much cleaner and safer, reducing the risk of accidents during installation.

6. Compatibility:

   • The EXF9-S28x1MI fitting is compatible with various types of pipe materials, including copper, PEX, and multilayer pipes. This makes it highly versatile and suitable for different types of plumbing and heating systems.
   • The 1-inch male-threaded connection is designed to fit 1-inch female-threaded components, offering a seamless connection to valves, pumps, manifolds, and other threaded parts, making it ideal for a wide range of plumbing and heating systems.
   • It is compatible with press-fit tools that are suitable for 28mm pipes, making the installation process straightforward and efficient.
