Elbow press 90° - female thread, 3/4" F x 20

Product detailed description

This press elbow is used in heating and plumbing systems where a 90° directional change is required between an ALPEX pipe and an internal thread. It is commonly installed in residential and commercial buildings for applications such as underfloor heating, hot water distribution, and central heating systems. The elbow is designed for use with ALPEX pipe systems and is compatible with press tools that use B-F-TH type jaws. The nickel-plated brass construction provides resistance to corrosion and ensures long-term durability in environments with moderate temperatures and pressures.

Installers typically use this elbow in systems where the pipe must connect to a threaded fitting such as a valve, meter, or manifold. The elbow is suitable for both new installations and system repairs. It is important to ensure that the ALPEX pipe is correctly prepared and that the press tool is calibrated to the correct pressure to avoid leaks or improper connections.

Technical parameters

Installation and connection

The installation process involves cutting and deburring the ALPEX pipe to the correct length, inserting it into the elbow, and then pressing the fitting using a tool compatible with B-F-TH type jaws. The elbow has a 3/4 inch female thread on one end and a 20 mm press connection on the other. It is important to verify that the press tool is correctly aligned and that the pipe is fully inserted into the fitting before pressing. Common installation errors include insufficient pipe insertion, incorrect press tool alignment, and failure to clean the pipe before installation.

Compatibility and accessories

This press elbow is specifically designed for use with ALPEX pipes and is compatible with press tools that support B-F-TH type jaws. To complete the installation, the press tool and the appropriate press jaws must be available. No additional fittings are required for this elbow. The internal thread allows for direct connection to standard threaded components such as valves or manifolds. Installers should ensure that the system pressure and temperature requirements match the elbow's specifications before installation.

Technical background for designers

The elbow functions by creating a directional change in the piping system while maintaining a secure and leak-free connection. The nickel-plated brass CW617N material is selected for its resistance to corrosion and its ability to maintain structural integrity under normal operating conditions. The EPDM seal ensures a tight connection between the pipe and the fitting. The elbow is designed to integrate into systems with moderate pressure and temperature requirements. The service life of the elbow is influenced by the quality of the press connection, the condition of the pipe, and the operating environment. Proper installation and regular inspection are key to maintaining system efficiency and preventing failures.

Service and operation

During operation, the elbow requires no active maintenance. However, it is important to inspect the connection for signs of leakage or wear, particularly after installation or following system pressure changes. If a leak is detected, the fitting should be removed and replaced. No specific service intervals are required for this elbow, as it is designed for long-term use in stable operating conditions. The nickel-plated brass construction ensures resistance to corrosion, reducing the need for frequent maintenance.

Frequently asked questions

Can this elbow be used with other pipe materials besides ALPEX?
No, this elbow is specifically designed for use with ALPEX pipes and is not compatible with other pipe materials.

Is the internal thread suitable for high-pressure systems?
The internal thread is suitable for systems with a nominal pressure of PN 10. It is not recommended for use in systems with higher pressure requirements.

Can the elbow be used in steam systems?
The elbow is rated for a maximum operating temperature of +120°C, which makes it suitable for steam systems within this temperature range.

What press tool is required for installation?
A press tool compatible with B-F-TH type jaws is required for installation. The tool must be calibrated to the correct pressure for the fitting size.
