Nipple PRESS - copper, Cu 28 x 32

Product detailed description

Press copper nipples are essential components in modern heating and plumbing systems where cross-connections between different pipe materials are required. This type of fitting is commonly used in residential and commercial buildings during the installation of central heating, hot water distribution, and underfloor heating systems. Installers frequently encounter the need to connect flexible ALPEX piping to rigid copper lines, particularly in areas where space constraints or system design require flexibility and durability. The IVAR 510068 is specifically designed for such applications, ensuring a secure and leak-free connection using press or crimping tools.

Proper selection and installation of press fittings are critical to system integrity. The dimensions and material properties of the fitting must align with the system's operating conditions, including temperature and pressure. The IVAR 510068 is suitable for systems operating at up to +120°C and PN10 pressure, making it ideal for hot water and heating circuits. Its nickel-plated brass construction provides resistance to corrosion and wear, while the EPDM sealing ring ensures a reliable seal under varying thermal conditions.

The operating temperature limit of +120°C and PN10 pressure rating are key factors in system design and component selection. These values determine the suitability of the fitting for hot water and heating applications. The material selection—nickel-plated brass CW617N—ensures compatibility with copper and ALPEX piping, while the stainless steel sleeve and EPDM O-ring contribute to long-term sealing performance. These parameters are essential for ensuring the fitting meets the required safety and performance standards in professional installations.

Installation and connection

The IVAR 510068 press copper nipple is installed using a press or crimping tool compatible with the IVAR.TR 4430 system. The fitting connects to ALPEX pipe on one end and copper pipe on the other. Before installation, ensure that the pipe ends are clean and free from burrs or debris. The press tool must be correctly aligned with the fitting to ensure even deformation of the sleeve and secure connection. A common mistake is applying uneven pressure during pressing, which can lead to leaks or reduced sealing effectiveness. Always verify the tool is set to the correct pressing force and that the tooling is in good condition to avoid misalignment or incomplete deformation.

Compatibility and accessories

The IVAR 510068 is specifically designed for use with ALPEX and copper piping systems. It is compatible with press tools from the IVAR.TR 4430 series. For complete system integration, ensure that all fittings and tools are from the same manufacturer to maintain consistency in performance and reliability. No additional accessories are required for standard installation, but it is recommended to have spare O-rings on hand for replacement during maintenance or rework. This fitting is not interchangeable with other press systems due to differences in tooling and sealing mechanisms.

Technical background for designers

The operating principle of the IVAR 510068 is based on mechanical deformation of the stainless steel sleeve during pressing, which compresses the EPDM O-ring against the pipe surface to create a watertight seal. The nickel-plated brass body provides structural strength and resistance to chemical and thermal degradation. The material combination ensures compatibility with both copper and ALPEX piping, reducing the risk of galvanic corrosion. The design allows for integration into both rigid and flexible piping systems, making it suitable for applications where thermal expansion and contraction are expected. The long-term performance of the fitting depends on correct installation, system pressure, and temperature conditions, as well as the quality of the sealing interface between the O-ring and the pipe.

Service and operation

Routine maintenance for the IVAR 510068 is minimal due to its durable construction and reliable sealing mechanism. However, periodic visual inspections are recommended to check for signs of wear, corrosion, or leakage. If a leak is detected, the fitting should be replaced rather than repaired, as the integrity of the press connection cannot be restored once compromised. No scheduled service intervals are required for this component under normal operating conditions. In high-temperature or high-pressure environments, more frequent inspections may be necessary to ensure continued performance.

Frequently asked questions

Can the IVAR 510068 be used with other press systems?
No, the fitting is designed specifically for use with IVAR.TR 4430 press tools and should not be used with other press systems due to differences in tooling and sealing mechanisms.

Is the EPDM O-ring replaceable?
Yes, the O-ring is a separate component and can be replaced if damaged or worn during installation or maintenance. Replacement should be done with an identical EPDM O-ring to maintain sealing performance.

Can the fitting be used in cold water systems?
Yes, the fitting is suitable for both hot and cold water applications. The operating temperature range includes temperatures below +120°C, making it compatible with cold water systems as well.

What is the maximum allowable pressure for this fitting?
The fitting is rated for PN10 pressure, which corresponds to a maximum allowable working pressure of 10 bar at operating temperatures up to +120°C.
