T-piece press - reduced, 40 x 40 x 32

Product detailed description

Press T-pieces are commonly used in central heating systems, domestic hot water circuits and industrial piping applications where branching is required. They allow for the connection of three pipe runs at right angles, with one branch having a reduced diameter. This component is frequently found in underfloor heating manifolds, boiler connections and radiator circuits. Installers working with ALPEX cross-linked polyethylene pipes will encounter these fittings in both new builds and renovation projects.

The design allows for quick and secure installation using a hydraulic press tool compatible with the fitting’s dimensions. It is suitable for use in closed-loop systems where thermal expansion and contraction are expected. The nickel plating provides corrosion resistance, while the EPDM sealing ring ensures a tight connection. The fitting is intended for use in systems operating within the specified pressure and temperature limits.

Technical parameters

Installation and connection

This press T-piece is installed using a hydraulic pressing tool compatible with the ALPEX system. The fitting has three connection points: two at 40 mm and one at 32 mm. The press marks must be clearly visible after installation to confirm correct engagement. Before pressing, ensure the pipe ends are clean and free of burrs. Common installation errors include incorrect alignment, insufficient pressing force, or using a tool not calibrated for ALPEX pipes. After installation, inspect the pressed joint for even deformation and verify the fit with a go/no-go gauge if available.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX cross-linked polyethylene pipes. It requires a stainless steel sleeve and an EPDM sealing ring for a secure connection. The EPDM material is compatible with the B-F-TH jaw type of pressing tools. No additional related products are listed for this item. When ordering, ensure all necessary components such as sleeves and seals are included to complete the installation.

Technical background for designers

The operating principle of this T-piece relies on the deformation of the metal fitting around the pipe when pressed. The nickel-plated brass CW617N offers high tensile strength and resistance to thermal cycling, making it suitable for long-term use in heating systems. The EPDM sealing ring ensures a leak-free connection and is resistant to thermal expansion. Integration into the system depends on the correct selection of pipe size and pressing tool. Long-term performance is influenced by adherence to installation standards and the quality of the pressing process.

Service and operation

There are no scheduled maintenance requirements for this press T-piece under normal operating conditions. During routine inspections, check for signs of mechanical damage, corrosion or leakage at the joints. The integrity of the press mark should also be verified. If any defects are found, the fitting must be replaced following the same installation procedure. No service intervals are specified in the provided data.

Frequently asked questions

Can this press T-piece be used with copper pipes?
No, this fitting is specifically designed for ALPEX cross-linked polyethylene pipes and requires a stainless steel sleeve for installation.

Is this fitting suitable for outdoor installations?
Only if installed in a protected location and within the specified temperature and pressure limits.

What pressing tool is required for installation?
A pressing tool compatible with the B-F-TH jaw type is required to ensure proper deformation and sealing.

Can the EPDM sealing ring be replaced separately?
Yes, the sealing ring can be replaced if damaged, but the fitting must be removed from the pipe before replacement.
