Turn piece PRESS, 20 x 16 x 16

Product detailed description

Press T-pieces are essential components in the installation of heating systems, particularly in residential and commercial buildings where precise pipe routing is required. Installers and technicians use these fittings to create branch connections in closed-loop systems, such as underfloor heating or radiator circuits. The compact dimensions and high-pressure rating make this fitting suitable for tight spaces and systems with moderate flow rates. When working with ALPEX piping, the press connection method ensures a secure and leak-free joint without the need for soldering or threading.

Proper selection and installation of press T-pieces are critical for system performance. The nominal pressure and temperature ratings must align with the system’s operating conditions. This fitting is designed for use with ALPEX pipes of varying diameters, allowing for flexible layout design. The nickel-plated brass body and EPDM sealing ring provide resistance to corrosion and thermal expansion, ensuring long-term reliability in heating applications.

Technical parameters

Installation and connection

Installation of the press T-piece requires a press tool compatible with ALPEX piping. The fitting is inserted onto the prepared pipe ends, ensuring that the stainless steel sleeve is fully seated. The press tool is then used to compress the sleeve around the pipe, forming a secure joint. The connection sizes are 20 mm, 16 mm, and 16 mm, allowing for a branch connection between different pipe diameters. It is important to verify that the pipes are cut cleanly and free of burrs before installation. Common mistakes include misalignment of the fitting or insufficient compression, which can lead to leaks or reduced system efficiency.

Compatibility and accessories

This press T-piece is specifically designed for use with ALPEX pipes. It is compatible with standard press tools used in the installation of ALPEX piping systems. No additional accessories are required for installation, as the fitting includes the necessary sealing ring and sleeve. It is important to ensure that the system’s other components, such as valves and manifolds, are also press-compatible to maintain a consistent installation method. Related products include other press fittings such as elbows, couplings and straight connectors for ALPEX piping.

Technical background for designers

The press connection method relies on the deformation of the stainless steel sleeve to create a tight seal between the fitting and the pipe. The nickel-plated brass body provides good thermal conductivity and mechanical strength, while the EPDM sealing ring ensures a watertight connection. The CW617N brass alloy is chosen for its resistance to corrosion and its ability to maintain dimensional stability under thermal cycling. In system design, the nominal pressure and temperature ratings must be considered to ensure that the fitting can withstand the expected operating conditions. The compact size and multi-diameter compatibility make this fitting suitable for complex layouts and tight spaces.

Service and operation

Once installed, the press T-piece requires minimal maintenance. The nickel-plated brass body and EPDM sealing ring are resistant to corrosion and degradation under normal operating conditions. There are no scheduled service intervals for this fitting, as it is designed for long-term use without the need for re-tightening or replacement. During system inspections, it is recommended to check for signs of leakage or mechanical damage, particularly in areas where the fitting is exposed to external stress or vibration.

Frequently asked questions

Can this press T-piece be used with copper pipes?
No, this fitting is specifically designed for ALPEX pipes. Using it with copper pipes would require a different type of connection method and may compromise the integrity of the joint.

What is the maximum working temperature for this fitting?
The maximum operating temperature is +120 °C, which is suitable for most heating applications, including underfloor heating and radiator circuits.

Is it possible to reuse the press T-piece after installation?
No, once the press tool has been used to compress the sleeve, the fitting cannot be reused. A new fitting must be installed if the connection needs to be modified or replaced.

What is the nominal pressure rating of this press T-piece?
The nominal pressure rating is PN 10, meaning it is suitable for systems operating at up to 10 bar. This rating should be considered when designing the system to ensure compatibility with the overall pressure requirements.
