Pipe Tee fitting Detal-met TR20 — 20 mm, press-fit plumbing connector

Detal-met TR20 — 20 mm pipe tee fitting is a T-shaped connector intended for plumbing and heating installations. It creates a perpendicular branch from a main 20 mm pipeline to another 20 mm line, enabling straightforward distribution and routing of potable water and central heating circuits. The fitting is suitable for systems that use press-fit or compatible mechanical joining methods and is designed for standard 20 mm copper, stainless, or compatible pipe materials in residential and light-commercial applications.

Advantages

The Detal-met TR20 tee offers a compact design for clean branch connections while maintaining consistent internal flow diameter across all three outlets. Its geometry reduces turbulence and pressure loss at the junction compared with improvised fittings, and it is compatible with common press-fit assemblies, providing reliable mechanical joints when installed with the appropriate press tools and fittings. The product is corrosion-resistant when used with appropriate pipe materials and provides a durable connection for potable water and heating circuits.

Suitable for

• Creating distribution tees in potable water supply systems
• Branching 20 mm central heating loops
• Extending or re-routing runs in residential plumbing
• Light-commercial plumbing and heating installations requiring press-fit connections

Key specifications

• Nominal diameter: 20 mm on all three outlets
• Configuration: T-shaped branch connector (equal tee)
• Connection method: designed for press-fit or compatible mechanical joining
• Intended media: potable water and central heating fluids
• Typical compatible pipe materials: copper, stainless steel, and other press-compatible 20 mm pipes

How to use

Prepare the pipeline by cutting the main and branch pipes squarely and deburring the cut edges. Ensure pipe ends and fitting contact surfaces are clean and free from oil, dirt, and oxidation. Assemble the tee by inserting the prepared pipe ends fully into the fitting sockets following the manufacturer’s seating marks or depth guides. For press-fit installations, position the appropriate press jaws around the fitting socket and perform the press operation with a calibrated pressing tool according to the press tool and fitting manufacturer instructions. Verify each joint visually and, if applicable, by applying pressure testing to the system to check for leaks before putting the installation into service.

Usage recommendations

Use only pipes and press tools compatible with 20 mm press-fit fittings. Follow local plumbing codes and the press tool manufacturer’s instructions for joint formation and pressure testing. When installing in heating systems, consider thermal expansion allowances and use appropriate supports and insulation where required.
