Press bushing - sleeve nut, 2" F x 63

Product detailed description

Press bushings with sleeve nuts are commonly used in heating and plumbing systems where rigid connections between plastic and metal piping are required. This model is suitable for connecting ALPEX pipes to a 2 inch external thread. It is typically used in residential and commercial buildings for central heating systems, hot water distribution, and other applications where a secure and leak-free connection is essential. The installation involves pressing the fitting onto the pipe and securing it with a sleeve nut and washer to ensure a tight seal.

Such fittings are often installed in conjunction with press tools and clamping jaws of type B-F-TH. The connection must be made with precision to avoid misalignment or damage to the pipe or fitting. The operating conditions must also be considered, particularly the maximum temperature and pressure limits, to ensure long-term performance and safety.

Technical parameters

Code	510083
Brand	IVAR

The operating temperature limit of +120°C and pressure rating of PN 10 are critical for selecting this fitting for systems with hot water or heating circuits. The material properties of nickel-plated brass and EPDM ensure compatibility with these conditions. These parameters help determine the suitability of the fitting for specific system requirements and installation environments.

Installation and connection

To install the press bushing with sleeve nut, the ALPEX pipe must first be cut to the correct length and deburred. The sleeve nut and washer are then placed over the pipe before the fitting is pressed into place using a suitable press tool. The sleeve nut is tightened by hand to secure the connection. It is important to ensure that the pipe is fully inserted into the fitting and that the sleeve nut is not over-tightened, which could damage the EPDM washer or the fitting itself. A common mistake is using the wrong press tool or clamping jaws, which can lead to an incomplete or faulty connection.

Compatibility and accessories

This press bushing is specifically designed for use with ALPEX pipes and requires a press tool compatible with the B-F-TH jaw type. No additional accessories are required for standard installation. It is important to ensure that all components, including the press tool and clamping jaws, are correctly matched to avoid damage or failure of the connection.

Technical background for designers

This press bushing operates by forming a mechanical and hydraulic seal between the ALPEX pipe and the brass fitting. The nickel-plated brass body provides corrosion resistance and durability, while the EPDM washer ensures a tight seal against leakage. The stainless steel sleeve adds structural support and helps maintain alignment during installation. The integration into the system depends on the correct sizing and alignment of the pipe and fitting. The service life and efficiency of the connection are influenced by the quality of the installation, the operating conditions, and the compatibility of the materials used.

Service and operation

No regular maintenance is required for this press bushing during normal operation. However, it is important to periodically inspect the connection for signs of leakage or wear, particularly in high-temperature or high-pressure environments. Any damage to the sleeve nut or washer should be addressed immediately to prevent system failure.

Frequently asked questions

Can this press bushing be used with other types of plastic pipe besides ALPEX?
No, this bushing is specifically designed for use with ALPEX pipes. Using it with other types of pipe may result in a faulty or insecure connection.

What type of press tool is required for installation?
A press tool with clamping jaws of type B-F-TH is required to ensure a correct and secure connection.

Is it possible to reuse the sleeve nut after installation?
No, the sleeve nut is intended for single use only. Reusing it may compromise the integrity of the connection and lead to leaks.

What is the maximum operating temperature for this fitting?
The maximum operating temperature is +120°C. Exceeding this limit may cause the EPDM washer to degrade and affect the seal.
