T-piece press - reduced, 32 x 26 x 26

Product detailed description

Press T-pieces are essential in the installation of heating and plumbing systems using ALPEX pipes, particularly in residential and commercial buildings where pipe diameters vary. These fittings are used in closed-loop systems such as underfloor heating, domestic hot water circuits and central heating applications. Installers frequently encounter situations where branching is needed between different-sized pipes, and a press T-piece provides a compact, leak-free solution. The design allows for a secure connection without the need for soldering or threading, reducing installation time and ensuring long-term reliability.

When selecting and sizing a press T-piece, it is important to consider the nominal pressure rating and maximum operating temperature of the system. The fitting must match the pipe sizes and wall thicknesses of the connected components. Correct alignment and pressing technique are critical to avoid misalignment and potential leakage points. This press T-piece is suitable for use with ALPEX pipes of different diameters and is intended for permanent installation in closed systems.

Technical parameters

Installation and connection

Installation involves cutting the ALPEX pipes to length, deburring the ends, and positioning the press T-piece between the connected pipes. The press tool must be set to the correct position according to the manufacturer’s guidelines to ensure even pressure distribution around the fitting. The connection size is 32 x 26 x 26 mm, meaning it connects one 32 mm pipe to two 26 mm pipes. During installation, it is crucial to check that the pipes are clean and free from debris before pressing to prevent internal blockages. A common mistake is applying uneven pressure during pressing, which can lead to weak joints and eventual leaks.

Compatibility and accessories

This press T-piece is designed for use with ALPEX pipes and must be used with compatible pressing tools and dies. The fitting includes a stainless steel sleeve and an EPDM sealing ring, both of which are integral to the connection. For full functionality, the installer must ensure the use of press tools compatible with the B-F-TH type jaws. Additional components such as straight press fittings or elbows may also be required depending on the layout of the system. No alternative products are recommended for this application.

Technical background for designers

The press T-piece operates by compressing the stainless steel sleeve around the pipe wall using a hydraulic or mechanical press. The EPDM seal ensures a watertight connection by filling any minor surface irregularities. The nickel-plated brass CW617N material offers good thermal conductivity and resistance to scaling, making it suitable for long-term use in closed systems. The design allows for minimal pressure loss and uniform flow distribution in branched circuits. The service life is influenced by the quality of the pressing process, the chemical composition of the fluid, and the presence of particulate matter in the system.

Service and operation

Once installed, this press T-piece requires no regular maintenance due to its sealed design. However, periodic visual inspections should be carried out to check for signs of corrosion or mechanical stress. If a leak occurs, the entire section must be replaced, as individual components cannot be disassembled. There are no specified service intervals for this component, as it is intended for permanent use in closed systems.

Frequently asked questions

Can this press T-piece be used with copper or steel pipes?
No, it is specifically designed for ALPEX pipes and cannot be used with other pipe materials.

Is the EPDM seal compatible with aggressive fluids?
The EPDM seal is suitable for use with potable water and heating fluids, but not with solvents or chemicals outside the standard range.

What pressing tools are compatible with this fitting?
Tools compatible with the B-F-TH type jaws are required for proper pressing and sealing.

Can the fitting be reused after removal?
No, once pressed, the fitting must be replaced as reusing it could compromise the integrity of the connection.
