T-piece press - reduced, 40 x 26 x 40

Product detailed description

Press T-pieces are essential components in heating and plumbing systems where branching is required at different pipe diameters. This model is commonly used in residential and commercial buildings for hydronic heating, domestic hot water, and other low-pressure fluid systems. Installers often encounter situations where a branch connection is needed between pipes of varying sizes, and this T-piece provides a secure and leak-free solution. It is particularly suited for systems operating at moderate temperatures and pressures, where reliable sealing and long-term performance are critical.

When selecting and sizing press fittings, it is important to consider the system pressure and temperature conditions. This T-piece is designed for PN10 systems and can operate continuously at temperatures up to +120°C. The dimensions of the T-piece allow it to connect ALPEX pipes of different sizes, ensuring compatibility with a range of pipe diameters in the same system. The nickel-plated brass body and stainless steel sleeve contribute to its resistance to corrosion and mechanical stress.

Technical parameters

The nominal pressure rating of PN10 indicates that the fitting is suitable for systems operating at up to 10 bar. The maximum operating temperature of +120°C makes it appropriate for hot water and heating applications. The material selection ensures compatibility with the thermal expansion and contraction of the connected pipes, reducing the risk of stress fractures or leaks over time.

Installation and connection

This press T-piece is installed using a press tool compatible with B-F-TH type jaws. The connection sizes are 40 mm, 26 mm, and 40 mm, allowing it to connect two 40 mm pipes to a 26 mm branch. Before installation, the installer should ensure that the ALPEX pipes are cut cleanly and that the ends are free from burrs or debris. The press tool must be correctly aligned with the fitting to ensure even pressure is applied during the pressing process. Common installation errors include misalignment of the tool, insufficient pressure during pressing, and using incorrect jaws for the fitting type. These can lead to weak connections and potential leaks.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX pipes and must be used with the appropriate press tools and EPDM seals. The stainless steel sleeve and EPDM seal are included as part of the fitting. Installers should ensure that the press tool is calibrated and compatible with the B-F-TH jaw type to achieve a secure connection. No additional products are required for standard installation, but it is important to verify the compatibility of the press tool and jaws with the fitting before use.

Technical background for designers

The press T-piece operates by mechanically securing the ALPEX pipe within the fitting using a stainless steel sleeve and EPDM seal. The nickel-plated brass body provides a durable and corrosion-resistant housing, while the stainless steel sleeve ensures a tight fit and prevents pipe slippage. The EPDM seal is resistant to thermal expansion and maintains a watertight connection under varying temperature conditions. The design allows for integration into systems with different pipe diameters, making it suitable for branch connections in heating and plumbing circuits. The service life and efficiency of the fitting depend on correct installation, proper tooling, and the absence of mechanical stress from pipe misalignment or thermal movement.

Service and operation

Once installed, this press T-piece requires no regular maintenance. However, during system inspections, it is advisable to check for signs of leakage, corrosion, or mechanical damage. If any issues are detected, the fitting should be replaced immediately. No specific service intervals are required for this model, as it is designed for long-term use under normal operating conditions. The EPDM seal and stainless steel sleeve are not replaceable and must be replaced with the entire fitting if damage occurs.

Frequently asked questions

Can this T-piece be used with other types of pipe besides ALPEX?
No, this T-piece is specifically designed for ALPEX pipes and must not be used with other pipe types.

Is it compatible with press tools from other manufacturers?
It must be used with press tools compatible with B-F-TH type jaws. Using other tools may result in an insecure connection.

What is the maximum operating temperature for this fitting?
The maximum operating temperature is +120°C, as specified in the technical parameters.

Can the EPDM seal be replaced separately?
No, the EPDM seal is part of the fitting and cannot be replaced individually. The entire fitting must be replaced if the seal is damaged.
