Knee press 90°, 50 x 50

Product detailed description

Press elbows 90° are essential components in the installation of heating and plumbing systems where directional changes in piping are required. This particular model is commonly used in residential and commercial buildings for connecting ALPEX pipes of equal diameter. Installers working on central heating systems, hot water circuits, or underfloor heating layouts will find this fitting suitable for applications where a 90° turn is needed without the use of multiple components. The fitting is designed for use with press tools compatible with B-F-TH type jaws, ensuring a secure and leak-free connection.

Correct selection and installation of press fittings are crucial for the long-term performance of the system. The operating conditions, including temperature and pressure, must align with the fitting's specifications to prevent premature failure. This model is intended for use in systems operating at up to +120 °C and PN 10 pressure levels, making it suitable for a wide range of heating and hot water applications.

Technical parameters

Installation and connection

Installation of the press elbow involves positioning the fitting over the prepared pipe ends and using a press tool to compress the sleeve around the pipe. The connection size corresponds to the ALPEX pipe diameter, and the press tool must be calibrated for the specific fitting type. It is important to ensure that the pipe ends are clean and free from burrs before installation. Common installation mistakes include incorrect press depth, misalignment of the fitting, and using an incompatible press tool, which can lead to a weak or leak-prone connection.

Compatibility and accessories

This press elbow is specifically designed for use with ALPEX pipes of the same diameter. To complete the installation, the appropriate press tool compatible with B-F-TH type jaws must be used. No additional accessories are required for the basic installation, but it is important to ensure that all components are from the same manufacturer to guarantee compatibility and system integrity.

Technical background for designers

The press elbow operates by compressing a stainless steel sleeve around the ALPEX pipe, creating a secure mechanical and watertight connection. The nickel-plated brass body provides durability and resistance to corrosion, while the EPDM sealing ensures a tight fit. The integration of the fitting into the system depends on the correct alignment of the press tool and the pipe. The service life of the fitting is influenced by the quality of the installation, the operating conditions, and the compatibility of the press tool used.

Service and operation

Once installed, the press elbow requires minimal maintenance. Regular visual inspections should be carried out to check for signs of wear, corrosion, or leakage. There are no scheduled service intervals for this fitting, as it is designed for long-term use without the need for adjustment or replacement. If any issues arise, the fitting should be replaced in accordance with the manufacturer's guidelines.

Frequently asked questions

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

Is it possible to reuse the press elbow after installation?
No, the press connection is a one-time installation and cannot be reused once the sleeve has been compressed.

Can the fitting be used in systems with higher operating temperatures?
No, the maximum operating temperature is specified as +120 °C, and exceeding this may compromise the integrity of the fitting.

What press tool is required for installation?
A press tool compatible with B-F-TH type jaws is required for this fitting to ensure a secure connection.
