No name Trójnik 40/40/90 pipe fitting T-joint 40/40/90

No name Trójnik 40/40/90 pipe fitting T-joint 40/40/90 is a T-shaped connector with three 40 mm outlets and a 90° branch angle. It is intended for joining or redirecting fluid or air flow in plumbing, ventilation or drainage systems. The fitting allows connection of three pipes of equal 40 mm diameter where one branch departs at a right angle, enabling compact routing in residential and light commercial installations.

Advantages

The T-joint provides a consistent 40 mm bore across all three inlets, ensuring uniform flow characteristics and simplified system design. Its 90° branch enables efficient direction changes without requiring additional adapters. The fitting is suitable for straightforward press-fit or solvent welding connections depending on pipe material, reducing installation time and complexity. Designed for common building systems, it supports both fluid and air applications where a right-angle split is needed.

Suitable for

• Domestic plumbing systems requiring a right-angle branch
• Ventilation ducting in small-scale or residential installations
• Drainage lines where three 40 mm pipes must be joined or redirected
• Repair or extension of existing 40 mm piping networks

Key specifications

• Nominal outlet diameter: 40 mm on all three connections
• Branch angle: 90° between the main run and the branch
• Configuration: T-shaped (three-way) fitting
• Intended media: fluids and air within compatible systems
• Application environments: residential and light commercial systems

How to use

Select compatible 40 mm pipes and ensure end faces are clean and free of debris before assembly. Fit the pipes into the three outlets until fully seated; depending on pipe material and local practice, secure joints using the recommended method such as solvent welding, adhesive, or suitable mechanical couplings. Ensure correct alignment so the 90° branch points in the desired direction and support connected pipe runs to avoid stress on the fitting. After installation, test the system for leaks or air-tightness following applicable standards.

Usage recommendations

Confirm material compatibility between the fitting and the pipe (PVC, ABS, or other) and follow local codes for solvent or mechanical jointing. Avoid exposing the fitting to temperatures, pressures, or chemicals outside the specifications of the piping system. Provide adequate support near the T-joint to prevent sagging or movement that could compromise the connection.
