SANHA reduction tee SANHA-Therm 3x female threaded 42 x 15 x 42 mm

The SANHA reduction tee SANHA-Therm 3x female threaded 42 x 15 x 42 mm is a threaded pipe fitting designed to join three pipes of differing diameters in heating and plumbing systems. Constructed for reliable threaded connections, it provides a compact branching and reduction point that integrates into hot-water and central heating installations. The fitting accepts two larger female-threaded connections at 42 mm and a smaller female-threaded connection at 15 mm, enabling a decrease in pipe size while maintaining a secure mechanical joint.

Advantages

This reduction tee offers a robust, threaded connection that simplifies installation and maintenance without the need for soldering or press tools. Its compact geometry reduces space requirements at branch points, and the threaded design enables easy disassembly for system changes or repairs. The product is suitable for use with standard plumbing threads and is intended for applications where threaded fittings are specified for hot-water and central heating systems.

Suitable for

• Joining and branching heating circuits in central heating systems
• Reducing pipe diameter between a 42 mm line and a 15 mm branch
• Hot-water distribution manifolds and local tap-offs
• Installations requiring threaded connections for ease of maintenance

Key specifications

• Connection type: three female threaded ports
• Size configuration: 42 mm, 15 mm, 42 mm
• Function: reduction tee for branching and downsizing pipe runs
• Application: hot-water and central heating systems
• Installation method: threaded assembly — no soldering required

How to use

Ensure system pressure is isolated and the pipes are prepared with clean, undamaged threads before installation. Apply an appropriate thread sealant or tape compatible with heating systems to male threads only, then hand-start the mating connections to avoid cross-threading. Tighten the connections with a suitable wrench, observing recommended torque limits for the pipe material and thread size. After assembly, pressurize and test the system for leaks before returning to service.

Usage recommendations

Use the SANHA-Therm reduction tee in systems where threaded fittings are specified and accessible for inspection. Choose compatible thread sealants rated for hot-water applications and follow local codes for pressure testing and installation. If disassembly is anticipated, avoid over-tightening to preserve thread integrity.
