Unequal Tee 15-22-15mm

The EXF9-T15x22x15 Unequal Tee 15-22-15mm is a press-fit fitting used in plumbing and heating systems to create a branch connection where a 15mm pipe is connected to a 22mm pipe. This unequal tee fitting has three ports: two 15mm ports and one 22mm port, forming a T-shape with unequal pipe sizes.

Key Features and Description:

1. Material:

   • The EXF9-T15x22x15 Unequal Tee is typically made from brass or stainless steel, which are durable and corrosion-resistant materials, perfect for water supply, heating, and other plumbing applications.
   • Brass is highly resistant to corrosion, making it a standard choice for plumbing systems exposed to water or heating elements, while stainless steel provides enhanced resistance to harsh conditions like high temperatures or aggressive water quality.

2. Design and Configuration:

   • Unequal Tee Design: The fitting is an unequal tee, where the main trunk of the tee is sized for 22mm pipe, and the two branches are for 15mm pipes. This allows you to create a branch connection with different pipe sizes.
   • Pipe Sizes:
     • 15mm on the two side branches.
     • 22mm on the main trunk.
   • This configuration is commonly used in systems where you need to reduce from a larger 22mm pipe to smaller 15mm branches for taps, radiators, or other fixtures.
   • Press-Fit Technology: The EXF9-T15x22x15 uses press-fit technology for quick and secure installation. The fitting is pressed onto the pipes using a press tool, creating a permanent, leak-proof seal without the need for soldering, heat, or additional sealing materials.

3. Press-Fit Technology:

   • The press-fit method eliminates the need for soldering, threading, or PTFE tape. It uses a press tool to compress the fitting onto the pipe, which creates a strong, permanent seal.
   • The press-fit process ensures a quick, safe, and reliable installation, especially in tight spaces or time-sensitive situations.
   • No open flames are involved, making it a cleaner and safer installation method compared to traditional soldering or threading.

4. Applications:

   • The EXF9-T15x22x15 Unequal Tee is ideal for use in a variety of plumbing and heating systems, where a branch connection is needed between different pipe sizes. Common applications include:
     • Domestic Plumbing: Creating a branch connection from a 22mm pipe to 15mm pipes for taps, radiators, or other plumbing fixtures.
     • Underfloor Heating (UFH): Connecting 22mm supply lines to 15mm distribution lines or radiators in UFH systems, where different pipe sizes are used for main supply and branching.
     • Central Heating Systems: Transitioning between 22mm main pipes and 15mm radiator pipes or branch connections for heating circuits.
     • Commercial Plumbing: Branching off 22mm supply pipes to 15mm pipes for smaller fixtures or components in commercial installations, such as sinks, faucets, or showers.

5. Advantages:

   • Quick and Efficient Installation: The press-fit technology enables faster installations, saving time and labor compared to traditional methods like soldering or threading.
   • Leak-Proof and Permanent Seal: The press-fit process ensures a reliable, leak-proof seal that will remain secure even under high pressure or fluctuating temperatures.
   • Corrosion Resistance: Made from brass or stainless steel, the fitting is highly durable and resistant to corrosion, ensuring it can handle a variety of water conditions, including those with higher mineral content or chemicals.
   • No Heat or Soldering Required: Since the fitting uses press-fit technology, there's no need for open flames, making it safer and cleaner than soldering.
   • Cleaner Installation: The absence of open flames or the need for sealing tape or compounds ensures that the installation is cleaner, with less mess and fewer hazards on the job site.

6. Compatibility:

   • The EXF9-T15x22x15 Unequal Tee is compatible with 15mm and 22mm pipes, making it suitable for a variety of pipe materials, including copper, PEX, and multilayer pipes when used with appropriate press-fit adapters.
   • The press-fit technology ensures a reliable connection with these materials, offering flexibility for different system types.
