T-piece press - PPSU - reduced, 26 x 32 x 20

Product detailed description

Reduced press T-pieces are commonly used in residential and commercial heating and plumbing systems to connect pipes of different diameters. These fittings are essential in systems where space constraints or design requirements necessitate a change in pipe size. Installers working with ALPEX pipe systems will find this fitting suitable for applications such as underfloor heating, domestic hot water, and central heating circuits. The PPSU material ensures compatibility with hot water and steam environments, making it suitable for high-temperature operations.

During installation, the T-piece allows for a branch connection to be made without the need for additional adapters or couplings. It is particularly useful in systems where a main pipe runs alongside a secondary branch, such as in manifold systems or where multiple zones require individual control. The fitting is designed to be used with press tools that compress the stainless steel clamp around the pipe, ensuring a secure and durable connection.

The operating temperature of +120°C and nominal pressure of PN 10 are key factors in determining the suitability of this T-piece for specific applications. These parameters ensure that the fitting can be used in systems with hot water or steam, such as underfloor heating or domestic hot water circuits. The material properties of PPSU allow for long-term stability under these conditions, making it a reliable choice for professional installations.

Installation and connection

The installation process involves preparing the ALPEX pipe ends, inserting them into the T-piece, and using a press tool to compress the stainless steel clamp around the pipe. The connection sizes are 26 mm, 32 mm, and 20 mm, allowing for a reduction in diameter at the branch connection. It is important to ensure that the pipe ends are clean and free from burrs before insertion. A common mistake is using an incorrect press tool or applying uneven pressure, which can lead to a weak or failed connection. Installers should also verify that the EPDM sealing ring is correctly positioned and undamaged before pressing.

Compatibility and accessories

This press T-piece is specifically designed for use with ALPEX pipes. It requires a compatible press tool for installation and should be used with other PPSU press fittings from IVAR for system consistency. No additional products are required for standard installation, but it is recommended to have spare EPDM sealing rings on hand for replacements. Related products include other PPSU press fittings such as elbows, couplings, and adapters, which can be used to complete the piping system.

Technical background for designers

The operating principle of this T-piece relies on the press-fit connection, where the stainless steel clamp is compressed around the pipe to create a mechanical and watertight seal. The PPSU material is chosen for its high thermal resistance and chemical stability, making it suitable for hot water and steam environments. The fitting integrates into the system by allowing a branch connection without the need for soldering or threading. The service life of the fitting is influenced by the operating conditions, particularly temperature and pressure, as well as the quality of the installation. Proper alignment and pressing are essential to ensure long-term performance.

Service and operation

Routine maintenance for this fitting is minimal, as the press connection is designed to be durable and leak-free. However, during system inspections, it is advisable to check for signs of wear on the EPDM sealing ring and ensure that the stainless steel clamp remains intact. If any damage is detected, the fitting should be replaced. There are no specific service intervals provided in the technical data, but regular visual inspections are recommended as part of general system maintenance.

Frequently asked questions

Can this T-piece be used with other types of pipe besides ALPEX?
No, this fitting is specifically designed for ALPEX pipes and will not provide a secure connection with other pipe types.

Is it possible to reuse the EPDM sealing ring after installation?
No, the sealing ring should not be reused once the fitting has been pressed. A new ring must be used for each installation to ensure a reliable seal.

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

What press tool is required for installation?
A compatible press tool for PPSU fittings must be used. The tool should be calibrated and suitable for the specified connection sizes.
