Pipe fitting T-piece Detal-met Trójnik PP 25 mm with 1/2" female threaded branch

Detal-met Trójnik PP 25 mm with 1/2" female threaded branch is a polypropylene T-piece intended for connecting a 25 mm spigot pipe run with a 1/2" threaded outlet. The fitting combines a smooth 25 mm socket for push-fit or solvent-weld connections and a 1/2" internal thread to accept standard threaded fittings, valves or adapters. Constructed from corrosion-resistant polypropylene, the component is suitable for low- to medium-pressure plumbing and fluid distribution systems where a transition from a plastic pipe line to a metal-threaded device is required.

Advantages

The polypropylene body provides chemical and corrosion resistance, reducing maintenance needs in potable water and non-aggressive fluid systems. The integrated 1/2" female thread offers compatibility with common threaded fittings and valves, enabling a secure transition point without additional adapters. The 25 mm socket is sized for standard pipe connections and supports quick installation methods. The design is lightweight and dimensionally stable, ensuring reliable alignment and sealing when installed according to standard practice.

Suitable for

• Domestic and commercial plumbing lines using 25 mm plastic pipe
• Connecting valves, pressure gauges or outlets with 1/2" male threads
• Heating return or distribution circuits with low- to medium-pressure requirements
• Fluid distribution systems where corrosion-resistant fittings are required

Key specifications

• Material: polypropylene (PP)
• Pipe socket size: 25 mm
• Threaded branch: 1/2" internal (female) thread
• Connection types: smooth socket for pipe connection and internal threaded outlet
• Typical application: plumbing, heating and fluid distribution systems

How to use

Prepare the 25 mm pipe end by cutting squarely and deburring. For solvent-weld or push-fit installation, follow the pipe system manufacturer's recommended joining procedure for polypropylene: clean and, if required, apply the appropriate adhesive or insert sealing components. Threaded components should be fitted into the 1/2" female branch using compatible 1/2" male-threaded fittings or valves; use suitable thread sealant tape or paste on the male thread to ensure a watertight joint. Assemble and torque connections according to the requirements of the connected components and local installation standards.

Usage recommendations

Do not expose the fitting to fluids or environments outside the chemical compatibility of polypropylene. Verify maximum operating pressure and temperature limits from the overall system specifications before installation and avoid excessive mechanical stress on the threaded branch when tightening to prevent damage to the plastic thread.
