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

Product detailed description

Press T-pieces are essential components in heating and plumbing systems where branch connections are needed. This model is commonly used in residential and commercial buildings for connecting different pipe diameters in systems operating at moderate temperatures and pressures. Installers working with ALPEX piping systems will find this fitting suitable for applications such as underfloor heating, domestic hot water distribution, and central heating circuits. The design allows for secure, leak-free connections without the need for soldering or threading, making it ideal for systems where flexibility and ease of installation are required.

When installing, the fitting is pressed onto the prepared ALPEX pipe ends using a compatible pressing tool. The press connection ensures a durable and reliable joint that is resistant to vibration and thermal expansion. The reduced configuration of this T-piece allows for the connection of two 26 mm pipes to a 20 mm branch, enabling efficient system design and space-saving layouts. It is particularly useful in systems where a smaller branch is needed for a secondary circuit or for connecting a valve or meter.

Technical parameters

The nominal pressure of PN 10 indicates that the fitting is suitable for systems operating at pressures up to 10 bar at 20°C. The maximum operating temperature of +120°C makes it appropriate for hot water and heating applications. The material selection, including nickel-plated brass and EPDM sealing, ensures compatibility with water and glycol-based heat transfer fluids. These parameters are essential for determining the suitability of the fitting for specific system conditions and for ensuring long-term performance.

Installation and connection

The installation process begins with cutting and deburring the ALPEX pipes to the required length. The T-piece is then slid onto the pipe ends, ensuring that the press marks are aligned. A pressing tool compatible with the fitting is used to apply the required force and create a secure connection. The press marks should be clearly visible after pressing to confirm a successful joint. It is important to use the correct pressing tool and to follow the manufacturer's instructions to avoid under- or over-pressing, which can lead to leaks or failure. Common mistakes include using incorrect tooling, failing to clean the pipe ends, or not verifying the press marks after installation.

Compatibility and accessories

This T-piece is specifically designed for use with ALPEX pipes and must be used with compatible pressing tools. It is not suitable for use with other pipe materials or connection methods. To complete the installation, additional components such as straight press fittings, elbows, and valves may be required. Installers should ensure that all components in the system are from the same manufacturer or are certified for use with ALPEX piping to maintain system integrity and performance.

Technical background for designers

The press connection operates by compressing the stainless steel sleeve around the pipe wall, creating a mechanical bond that is resistant to movement and leakage. The nickel-plated brass body provides corrosion resistance and durability, while the EPDM sealing ensures a tight joint. The material properties of CW617N brass allow for good thermal conductivity and mechanical strength, making it suitable for use in heating systems. The integration of this fitting into the system depends on the overall design, including pipe routing, flow rates, and pressure drop considerations. The service life of the fitting is influenced by the quality of the installation, the operating conditions, and the compatibility of the system components.

Service and operation

Once installed, the fitting requires no regular maintenance and is designed for long-term operation. However, it is important to inspect the press marks periodically to ensure that the connection remains secure. Any signs of leakage or movement should be investigated immediately. Since the fitting is a one-time press connection, it cannot be re-used if removed. There are no specified service intervals for this component, and no additional service parts are required for routine operation.

Frequently asked questions

Can the IVAR press T-piece 512008 be used with other pipe materials?
No, this fitting is specifically designed for ALPEX pipes and must not be used with copper, steel, or plastic pipes.

Is the EPDM sealing compatible with glycol-based heat transfer fluids?
Yes, the EPDM sealing is suitable for use with water and glycol mixtures commonly used in heating systems.

Can the press marks be re-pressed if the connection is not properly formed?
No, the fitting is designed for a single press operation. If the connection is not properly formed, the fitting must be replaced.

What pressing tool is required for this fitting?
A pressing tool compatible with ALPEX pipes and IVAR press fittings is required. The tool must be correctly sized for the fitting to ensure a secure connection.
