Elbow press 90° - male thread, 3/4" M x 26

Product detailed description

Press elbows are essential components in the installation of press-fitting systems, particularly in residential and commercial heating and plumbing applications. These fittings are used to change the direction of pipe runs and are commonly found in underfloor heating systems, hot and cold water distribution, and other press-fitting-based installations. Installers and technicians working with ALPEX pipes frequently use these fittings to ensure secure, leak-free connections in systems operating at moderate temperatures and pressures.

Proper selection and installation of press fittings are critical for the long-term performance of the system. The fitting must be compatible with the pipe material and the system's operating conditions. In systems with internal threaded connections, such as those found in valves or fixtures, press elbows provide a reliable transition from the flexible press-fitting system to the rigid threaded components.

The operating temperature of +120 °C and nominal pressure of PN 10 are key factors in determining the suitability of this fitting for specific applications. These parameters indicate that the fitting is appropriate for hot water systems and heating circuits operating within these limits. The material, nickel-plated brass CW617N, ensures good corrosion resistance and mechanical strength, making it suitable for use in both domestic and industrial environments.

Installation and connection

To install the press elbow, the installer must first ensure that the ALPEX pipe is cut cleanly and free of burrs. The pipe is then inserted into the fitting until it reaches the stop mark. A press tool is used to compress the fitting around the pipe, forming a secure, watertight connection. The male thread on the elbow is compatible with standard internal threads found in valves, fixtures, and other components. It is important to verify that the thread is clean and undamaged before tightening. Common installation errors include over-pressing the fitting, which can cause deformation, or under-pressing, which can lead to leaks. The connection size is 3/4 inch M x 26, and the fitting must be paired with the correct press tool for the pipe diameter.

Compatibility and accessories

This press elbow is specifically designed for use with ALPEX pipes and must be used in conjunction with the appropriate press tools and accessories. The fitting includes a stainless steel sleeve and an EPDM sealing ring, which are essential for ensuring a durable and leak-free connection. For installation, the press tool must be compatible with the fitting's dimensions and the pipe's wall thickness. No alternative or related products are specified for this model.

Technical background for designers

The press elbow operates by forming a mechanical and hydraulic seal between the pipe and the fitting. The nickel-plated brass CW617N material provides good resistance to corrosion and wear, making it suitable for long-term use in water-based systems. The EPDM sealing ring ensures flexibility and a tight seal, while the stainless steel sleeve reinforces the connection. The fitting's nominal pressure of PN 10 and operating temperature of +120 °C make it suitable for hot water and heating applications. The integration of the fitting into the system depends on the system's design pressure and temperature, as well as the compatibility of the press tool and the pipe material.

Service and operation

This press elbow requires no regular maintenance under normal operating conditions. However, during system inspections, it is advisable to check for signs of corrosion, deformation, or leakage. If any issues are detected, the fitting should be replaced immediately. No specific service intervals are provided in the technical data.

Frequently asked questions

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

Is it possible to reuse the fitting after it has been pressed?
No, once the fitting has been pressed onto the pipe, it cannot be reused and must be replaced if the connection is broken or damaged.

What is the maximum operating temperature for this fitting?
The maximum operating temperature is +120 °C, as specified in the technical parameters.

What is the nominal pressure rating of this press elbow?
The nominal pressure rating is PN 10, which means it is suitable for systems operating at up to 10 bar pressure.
