Tee fitting Detal-met Trójnik PP 20 mm with 1/2" female thread

Detal-met Trójnik PP 20 mm with 1/2" female thread is a polypropylene tee fitting designed to join three pipe runs in potable water, heating and general plumbing distribution systems. The fitting provides two 20 mm connections for continuous pipe sections and a 1/2" female threaded branch for attaching threaded valves, taps or components. Constructed from polypropylene, the tee is intended for residential and light commercial installations where corrosion resistance and chemical stability are required.

Advantages

The polypropylene construction ensures resistance to corrosion and common waterborne chemicals while keeping the fitting lightweight. The 20 mm ends are compatible with standard PP connection methods and offer a reliable mechanical or solvent-weld joint depending on installation practice. The 1/2" female thread enables direct mounting of threaded accessories without additional adapters, simplifying integration with valves and fixtures. Overall design supports a compact footprint and straightforward alignment during assembly.

Suitable for

• Potable water distribution in residential buildings
• Heating and radiator branch connections in small systems
• Plumbing installations where a threaded outlet is required for valves or fittings
• Light commercial piping systems with PP pipework

Key specifications

• Material: polypropylene (PP)
• Main pipe connection diameter: 20 mm (two ends)
• Branch connection: 1/2" internal (female) thread
• Application: potable water, heating, plumbing distribution
• Compatibility: designed for use with standard 20 mm PP pipe connections and 1/2" threaded components

How to use

Prepare pipe ends according to the connection method specified for the PP pipe — clean, deburr and, if required, apply appropriate solvent or use push-fit technique. Insert or join the 20 mm pipe ends into the corresponding fitting sockets and ensure correct alignment. For the threaded branch, apply thread sealant tape or suitable sealing compound to the male thread of the accessory, then hand-tighten and finish with a wrench to the manufacturer's recommended torque limits. Check for alignment and secure adjacent pipe supports to avoid stress on the fitting.

Usage recommendations

Use the fitting within the temperature and pressure limits of the polypropylene piping system, avoid exposure to direct UV where prolonged sunlight could degrade plastic components, and follow local plumbing codes. When connecting threaded metal components, ensure compatible materials and adequate sealing to prevent galvanic corrosion and leaks.
