T-piece press, 18 x 18 x 18

Product detailed description

This press T-piece is commonly used in residential and commercial heating and plumbing systems where a branch connection is required in an existing pipe run. Installers working with ALPEX piping systems will find this component suitable for applications such as underfloor heating circuits, domestic hot water distribution, and central heating manifolds. The design allows for quick and secure installation using standard pressing tools, ensuring leak-tight connections in both new builds and renovation projects.

The compact 18 x 18 x 18 mm dimensions make it ideal for tight spaces, while the nickel-plated brass construction ensures resistance to corrosion and mechanical wear. This fitting is intended for use with ALPEX pipes of the same diameter, ensuring compatibility and ease of installation in systems with uniform pipe sizes.

The nominal pressure rating of PN 10 indicates suitability for low-pressure systems, typically found in domestic heating and plumbing. The maximum operating temperature of +120°C makes it appropriate for hot water systems and radiant heating applications. These parameters are essential for determining correct sizing and ensuring long-term reliability in service.Installation and connection To install the press T-piece, first ensure the ALPEX pipe ends are clean and free of debris. Insert the pipe into the fitting until it reaches the stop mark. Use a pressing tool compatible with B-F-TH type jaws to apply even pressure around the circumference of the fitting. After pressing, verify the connection using a go/no-go gauge to confirm the correct depth and width of the press mark. Common mistakes include insufficient pressing force or misalignment, which can compromise the integrity of the joint. Always check the fit before proceeding to the next connection.Compatibility and accessories This T-piece is specifically designed for use with ALPEX pipes of the same diameter. It requires a pressing tool with B-F-TH type jaws for proper installation. Additional components such as straight press fittings or elbows may be needed depending on the layout of the system. Ensure that all fittings and tools are from the same manufacturer or certified for use with the specified pipe material.Technical background for designers The press connection operates by deforming the metal sleeve around the pipe wall, creating a mechanical and hydraulic seal. The nickel-plated brass CW617N offers high strength and corrosion resistance, making it suitable for long-term exposure to water and steam. The EPDM sealing material provides flexibility and maintains a tight seal under thermal expansion. Integration into the system depends on the flow rate and pressure requirements, with the PN 10 rating limiting the maximum allowable pressure. The operating temperature limit of +120°C is critical for systems involving hot water or radiant heating loops.Service and operation No regular maintenance is required for this fitting during normal operation. However, it is advisable to periodically inspect the system for signs of leaks or pressure loss, particularly after system start-up or following periods of inactivity. Any suspected faults should be investigated by disconnecting and re-pressing the affected joint using the correct tooling. No scheduled service intervals are specified for this component.Frequently asked questions

Can this T-piece be used with copper or PEX pipes?
No, this fitting is specifically designed for ALPEX pipes. Using it with other materials may result in an unreliable connection.

Is this fitting suitable for steam heating systems?
Yes, provided the operating temperature does not exceed +120°C and the pressure remains within the PN 10 limit.

Can multiple T-pieces be installed in series on a single pipe run?
Yes, provided each connection is made according to the manufacturer's instructions and the overall system pressure and flow are within acceptable limits.

What pressing tool is required for installation?
A pressing tool with B-F-TH type jaws is required to ensure a proper and consistent press.
