Press nipple - reduced, 18 x 20

Product detailed description

Press nipples are essential components in systems where pipes of different diameters need to be joined. In residential and commercial buildings, these fittings are commonly used in heating and plumbing systems to ensure a secure and leak-free connection. Installers working with ALPEX piping systems often encounter the need to connect dissimilar pipe sizes, making press nipples a vital part of the installation process. These fittings are particularly suited for applications where a compact and reliable connection is required, such as in underfloor heating circuits or domestic hot and cold water distribution systems.

When installing press nipples, it is important to ensure that the system is properly drained and depressurised. The fitting must be aligned correctly with the pipe ends, and the press tool must be applied with the correct force to form a secure joint. The nickel-plated brass construction provides good corrosion resistance, while the EPDM seal ensures a tight fit and compatibility with the B-F-TH type clamps.

Technical parameters

Installation and connection

Installation of the press nipple involves aligning the fitting with the pipe ends and applying the press tool according to the manufacturer's specifications. The connection sizes are 18 mm and 20 mm, which correspond to standard ALPEX pipe diameters. It is important to verify that the pipes are cut cleanly and that the fitting is seated correctly before pressing. Common installation mistakes include misalignment of the fitting or insufficient pressing force, both of which can compromise the integrity of the joint.

Compatibility and accessories

This press nipple is specifically designed for use with ALPEX pipes and is compatible with B-F-TH type clamps. When installing, it is necessary to ensure that the correct pressing tool is available for the specified pipe sizes. No additional accessories are required for basic installation, but it is recommended to have spare seals and clamps on hand in case of damage or wear during the process.

Technical background for designers

The press nipple operates by forming a mechanical joint between the pipe and the fitting through the application of pressure. The nickel-plated brass CW617N provides good mechanical strength and resistance to corrosion, making it suitable for use in a variety of environments. The EPDM seal ensures a tight fit and is compatible with the stainless steel sleeve, which helps to distribute the pressing force evenly. The integration of the fitting into the system depends on the system's pressure and temperature requirements, as well as the compatibility of the materials used in the overall installation.

Service and operation

Once installed, the press nipple requires minimal maintenance. Regular visual inspections can help identify signs of wear or damage. There are no specified service intervals for this component, but any signs of leakage or deformation should be addressed immediately. The long-term performance of the fitting is influenced by the quality of the installation and the operating conditions of the system.

Frequently asked questions

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

Is it possible to reuse the press nipple after it has been pressed?
No, once the fitting has been pressed, it cannot be reused and must be replaced if the connection needs to be altered.

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

What type of seal is used in this press nipple?
The fitting uses an EPDM seal, which is compatible with the stainless steel sleeve and ensures a tight connection.
