Grommet - male thread - N - 22mm-R1/2" IVAR.IVN81

Product detailed description

Press fittings are essential components in modern heating, plumbing, and industrial installations where reliable and leak-free connections are required. The IVAR IVN81.2212 is specifically designed for connecting 22mm press tube to a 1/2 inch male thread. This type of fitting is commonly used in residential and commercial buildings for central heating systems, hot and cold water supply, and industrial process lines. Installers working on these systems must ensure correct sizing and compatibility with the existing piping to maintain system integrity and performance.

Correct selection and installation of press fittings are critical to prevent leaks and ensure long-term durability. The IVAR IVN81.2212 is intended for use in press tube systems where a transition to a threaded connection is required. It is suitable for both new installations and system modifications, particularly where threaded components such as valves, meters, or regulators need to be integrated into a press tube network. The fitting is designed for use in environments with operating temperatures ranging from -20°C to +120°C and a nominal pressure of PN 16.

The technical parameters of the IVAR IVN81.2212 define its suitability for specific applications. The nominal pressure rating of PN 16 ensures it can handle medium-pressure systems, while the operating temperature range from -20°C to +120°C makes it suitable for both heating and cold water applications. These parameters are crucial for sizing and selecting the correct fitting to match the system requirements and environmental conditions.Installation and connection The IVAR IVN81.2212 is installed using a press tool that compresses the fitting around the press tube, creating a secure and leak-free connection. The press tube must be cut cleanly and deburred before installation. The fitting is then slid over the tube and aligned with the press tool. After pressing, the fitting must be checked for proper seating and the presence of a visible press mark. The 1/2 inch male thread is used to connect to threaded components such as valves or meters. Common installation errors include using incorrect tube dimensions, failing to clean the tube before pressing, or not verifying the press mark after installation.Compatibility and accessories The IVAR IVN81.2212 is compatible with standard 22mm press tube systems and threaded components with a 1/2 inch male thread. It is typically used in conjunction with other press fittings, valves, and meters in heating and plumbing systems. No additional accessories are required for basic installation, but it is recommended to have a press tool and measuring instruments on hand to ensure correct installation. Related products include other press fittings and threaded components from the same manufacturer.Technical background for designers The IVAR IVN81.2212 operates on the principle of mechanical compression, where the press tool deforms the fitting around the press tube to create a tight seal. The use of 1.4404 stainless steel ensures high corrosion resistance and mechanical strength, making it suitable for both indoor and outdoor applications. The EPDM O-ring provides a flexible seal that compensates for minor misalignments and thermal expansion. When integrating this fitting into a system, designers must consider the thermal expansion of the piping material, the pressure and temperature requirements, and the compatibility with other system components. The service life and efficiency of the fitting depend on correct installation, proper system design, and regular maintenance.Service and operation The IVAR IVN81.2212 requires minimal maintenance once installed correctly. Routine checks should include verifying the integrity of the press connection and the absence of leaks. If any issues arise, the fitting should be inspected for damage or wear. No specific service intervals are provided in the technical data, but it is recommended to perform periodic inspections as part of standard system maintenance. In the event of a leak, the fitting should be replaced rather than repaired, as the press connection is not designed for rework.Frequently asked questions

Can the IVAR IVN81.2212 be used with copper press tube?
No, the fitting is specifically designed for use with 22mm press tube made of the same material as the fitting. Using copper press tube would require a different fitting type.

Is the IVAR IVN81.2212 suitable for steam applications?
No, the operating temperature range does not include steam temperatures. The fitting is intended for use in water-based heating and plumbing systems.

Can the fitting be repressed after initial installation?
No, the press connection is not designed for rework. If the fitting becomes damaged or leaks, it must be replaced with a new unit.

What is the maximum allowable pressure for the IVAR IVN81.2212?
The fitting is rated for a nominal pressure of PN 16, which corresponds to a maximum allowable pressure of 16 bar under standard operating conditions.
