Press nipple - PPSU - reduced, 40 x 50

Product detailed description

Press fittings are essential components in modern heating and plumbing systems where reliable, leak-free connections are required. This type of fitting is commonly used in residential and commercial buildings for connecting flexible cross-linked polyethylene (ALPEX) pipes. Installers working on underfloor heating, domestic hot and cold water systems, and other low-pressure applications will find press fittings particularly useful due to their ease of installation and long-term durability. The fitting is designed for use with ALPEX pipes of different diameters, allowing for smooth transitions and system adaptability.

When working with press fittings, it is important to ensure that the correct tooling is used and that the pipe ends are properly prepared. The fitting must be fully seated and compressed using a compatible pressing tool to create a secure connection. This fitting is suitable for systems operating at moderate temperatures and pressures, making it ideal for a wide range of applications in both new builds and renovation projects.

The operating temperature of +120°C allows this fitting to be used in hot water systems, while the PN 10 pressure rating ensures compatibility with standard low-pressure systems. The PPSU material provides chemical resistance and dimensional stability under thermal stress, making it suitable for long-term use in heating and plumbing applications. These parameters are critical for correct sizing and selection to ensure system integrity and performance.Installation and connection The fitting is designed for use with ALPEX pipes of different diameters, with the connection sizes specified as 40 x 50. The installation process involves inserting the prepared pipe ends into the fitting and using a pressing tool to compress the stainless steel sleeve around the pipe. It is essential to verify that the pipe ends are clean, free from burrs, and properly aligned before pressing. Common installation mistakes include insufficient pressing force, misalignment of the pipe and fitting, and using incompatible pressing tools. These errors can lead to leaks or reduced service life.Compatibility and accessories This press fitting is specifically designed for use with ALPEX pipes and must be used in conjunction with a compatible pressing tool. The stainless steel sleeve and EPDM sealing ring ensure a tight and durable connection. No additional accessories are required for standard installation. Installers should ensure that all components are from the same manufacturer and system to maintain compatibility and system integrity.Technical background for designers The fitting operates by compressing the stainless steel sleeve around the ALPEX pipe, creating a mechanical bond that is sealed by the EPDM ring. The PPSU material is chosen for its high-temperature resistance and dimensional stability, making it suitable for use in hot water and heating systems. The PN 10 rating ensures that the fitting can withstand typical operating pressures without deformation or failure. The design allows for easy integration into existing systems and facilitates future maintenance or modifications.Service and operation This fitting requires no regular maintenance under normal operating conditions. However, it is important to periodically inspect the connection for signs of wear, corrosion, or leakage. If any issues are detected, the fitting should be replaced immediately to prevent system failure. No specific service intervals are required for this component.Frequently asked questions
