Elbow press 90° - female thread, 3/4" F x 26

Product detailed description

This 90° press elbow is designed for connecting ALPEX piping to internal threaded components in heating, plumbing and sanitation systems. The nickel-plated brass construction ensures resistance to corrosion and mechanical stress. It is commonly used in residential and commercial buildings for hot water supply lines, underfloor heating circuits and central heating installations. The fitting is intended for use with press tools of type B-F-TH, ensuring secure and leak-free connections.

Installers working on systems with internal threaded connections will find this elbow suitable for joining ALPEX pipe to valves, meters and other threaded equipment. The operating conditions include continuous temperatures up to +120°C and nominal pressure of PN 10. This makes the fitting appropriate for both domestic and industrial applications involving hot water and heating circuits.

The nominal pressure of PN 10 indicates the maximum allowable pressure under normal operating conditions, while the operating temperature of +120°C defines the upper limit for thermal resistance. These parameters are essential for selecting the correct fitting for a specific system, ensuring long-term durability and performance. The material, nickel-plated brass CW617N, provides good mechanical strength and corrosion resistance, making it suitable for use with water and glycol-based media.

Installation and connection

To install the press elbow, first ensure the ALPEX pipe is cut cleanly and free of burrs. Insert the pipe into the fitting until it reaches the stop mark. Use a press tool compatible with the B-F-TH type to apply even pressure around the circumference of the pipe. Verify the alignment of the elbow with the threaded component to avoid misalignment during tightening. Common installation errors include using non-compatible press tools or failing to clean the pipe end properly before pressing. Always double-check the connection after installation by applying system pressure and inspecting for leaks.

Compatibility and accessories

This press elbow is specifically designed for ALPEX pipes and is compatible with press tools of the B-F-TH type. For a complete installation, additional fittings such as straight couplings, unions and adapters may be required depending on the system layout. It is recommended to use stainless steel clamps and EPDM seals provided by the manufacturer to maintain system integrity and prevent leakage.

Technical background for designers

The elbow operates by forming a metal-to-metal seal between the press sleeve and the ALPEX pipe wall. The nickel-plated brass body offers high thermal conductivity and resistance to scaling and pitting. The EPDM gasket ensures a tight seal against the pipe and compensates for minor surface irregularities. When integrating into a system, designers should consider the flow characteristics and pressure drop across the elbow, especially in high-flow applications. The service life of the fitting is influenced by the quality of the press connection, the chemical composition of the transported medium and the presence of mechanical stress during installation.

Service and operation

During regular system inspections, check the elbow for signs of leakage, corrosion or mechanical damage. Ensure the press connection remains intact and the sealing surfaces are free from debris. There are no scheduled service intervals specified for this fitting, but any issues with the connection should be addressed immediately to prevent system failure.

Frequently asked questions

Can this press elbow be used with other types of pipe besides ALPEX?
No, this fitting is specifically designed for ALPEX piping and may not provide a reliable connection with other materials.

Is this elbow suitable for use with glycol-based heat transfer fluids?
Yes, the materials used are compatible with glycol-based fluids within the specified temperature and pressure limits.

What type of press tool is required for installation?
A press tool compatible with the B-F-TH type is required to ensure a proper and secure connection.

Can the elbow be disassembled after installation?
No, once pressed, the connection is permanent and cannot be reused or repositioned.
