T-piece press - reduced, 26 x 16 x 20

Product detailed description

This press T-piece is commonly used in residential and commercial buildings for connecting pipes in central heating, hot water supply and sanitation systems. It allows for branching in piping layouts where different diameters are required. Installers working with ALPEX pipe systems will find this fitting essential for creating secure and leak-free junctions in complex pipe networks. The fitting is typically used in concealed installations such as under floors, within walls or in mechanical rooms, where access for maintenance is limited.

The design ensures compatibility with standard pressing tools and provides a reliable seal in environments where thermal expansion and contraction are common. The nickel plating offers enhanced corrosion resistance, making it suitable for both wet and dry installation conditions. The fitting is intended for use in closed systems and should be selected according to the hydraulic requirements of the installation.

Technical parameters

Installation and connection

Before installation, ensure the ALPEX pipe ends are cut square and free from burrs. Insert the pipe into the fitting until it reaches the stop mark. Use a pressing tool compatible with type B-F-TH clamps to form a secure joint. Check that the pressing tool is correctly aligned and that the pipe is fully seated within the fitting. Common installation errors include misalignment of the tool, insufficient insertion depth of the pipe, or using non-compatible pressing tools. After pressing, verify the joint visually and perform a pressure test to confirm integrity.

Compatibility and accessories

This press T-piece is specifically designed for use with ALPEX pipes. It requires a pressing tool compatible with type B-F-TH clamps. The stainless steel clamp and EPDM sealing ring ensure a durable and watertight connection. When ordering, ensure that the appropriate pressing tools and any additional fittings for the same system are available. This fitting is not interchangeable with other pipe materials or systems outside the ALPEX range.

Technical background for designers

The operating principle relies on the deformation of the metal fitting around the pipe wall when pressed. The nickel-plated brass body (CW617N) offers good resistance to corrosion and mechanical stress. The EPDM seal ensures a tight connection and is compatible with water and steam-based heating systems. The integration into the system must consider thermal expansion and pressure fluctuations to ensure long-term performance. The service life is influenced by the quality of the pressing operation and the environmental conditions of the installation location.

Service and operation

No regular maintenance is required for this fitting during normal operation. However, after installation, inspect the pressing marks for symmetry and uniformity. In the event of suspected leaks or pressure loss, isolate the section and inspect the joint visually. If the pressing tool was misused or the pipe was not fully inserted, re-pressing may be necessary. There are no scheduled service intervals for this component unless specified in the system’s maintenance plan.

Frequently asked questions

Can this fitting be used with copper or plastic pipes?
No, it is specifically designed for ALPEX pipes. Using it with other materials may compromise the integrity of the connection.

Is it possible to re-use the fitting after pressing?
No, once the pressing tool has been applied, the fitting cannot be reused. A new fitting must be installed if the connection is broken or removed.

What pressing tools are compatible with this model?
Only pressing tools of type B-F-TH are suitable for forming a secure and durable connection with this fitting.

Can this fitting be used in steam systems?
Yes, provided the system operates within the maximum temperature limit of +120°C and the pressure does not exceed PN 10.
