Press bushing - sleeve nut, 6/4" F x 40

Product detailed description

Press bushings with sleeve nuts are commonly used in residential and commercial buildings for connecting flexible plastic piping systems to rigid threaded components. Installers working on heating, plumbing or sanitary systems often use these fittings to create leak-tight connections between ALPEX pipes and external threaded fittings. These fittings are particularly useful in applications where the pipe must pass through walls or floors and requires a secure, corrosion-resistant connection to a threaded pipe or valve.

When working with such fittings, the installer must ensure that the ALPEX pipe is correctly inserted into the fitting and that the sleeve nut is fully seated. The press connection is made using approved pliers or presses, ensuring the pipe is firmly secured against the sealing surface. This type of connection is preferred in systems where flexibility and ease of installation are required, and where the piping must withstand moderate temperatures and pressures.

The operating temperature limit of +120°C and nominal pressure of PN 10 are key factors in determining the suitability of this fitting for a particular system. These parameters are essential for sizing and selecting the correct component in accordance with the system's design requirements. The material composition, including nickel-plated brass and EPDM sealing, ensures compatibility with typical heating and plumbing media.

Installation and connection

To install the press bushing, the ALPEX pipe must be cut cleanly and inserted into the fitting until it reaches the stop. The sleeve nut is then threaded onto the external pipe fitting until it is fully seated. The press connection is made using pliers of type B-F-TH, ensuring the pipe is securely fixed. It is important to verify that the pipe is fully inserted and that the sleeve nut is tightened correctly to prevent leaks. A common mistake during installation is not seating the sleeve nut properly or using incorrect pressing tools, which can lead to a weak or failed connection.

Compatibility and accessories

This press bushing is specifically designed for use with ALPEX piping systems and is compatible with external threaded fittings of 6/4 inch F x 40 dimensions. It requires the use of approved pressing tools of type B-F-TH for a secure connection. No additional components are required for standard installation, but installers should ensure that all mating components are compatible with the system's operating conditions.

Technical background for designers

The press bushing operates by compressing the ALPEX pipe against a sealing surface using a sleeve nut and pressing tool. The nickel-plated brass body provides resistance to corrosion and wear, while the EPDM sealing ring ensures a tight seal against water and steam. The stainless steel sleeve adds structural support to the connection. The integration of this fitting into a system depends on the system's pressure and temperature requirements, as well as the compatibility of the mating components. The service life of the fitting is influenced by the quality of the installation and the operating conditions of the system.

Service and operation

This fitting does not require regular maintenance under normal operating conditions. However, periodic inspections should be carried out to check for signs of wear, leakage or corrosion. If any issues are detected, the fitting should be replaced immediately to prevent system failure. No specific service intervals are provided in the technical data.

Frequently asked questions

Can this press bushing be used with other types of plastic piping?
No, it is specifically designed for ALPEX piping and may not provide a secure connection with other materials.

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

What pressing tools are required for installation?
Pressing tools of type B-F-TH are required to ensure a secure connection.

Can the sleeve nut be reused after installation?
No, once the press connection is made, the sleeve nut should not be reused as it may compromise the integrity of the connection.
