Grommet - internally threaded - N - 22mm-Rp1" IVAR.IVN80

Product detailed description

This stainless steel grommet is commonly used in commercial and residential buildings for connecting press and threaded components in heating, plumbing, and industrial systems. It is frequently installed in central heating circuits, hot water distribution, and fire suppression systems. The component ensures a secure and leak-free connection between press-fitted pipes and threaded fittings. It is suitable for both new installations and system repairs, particularly in environments requiring resistance to corrosion and thermal expansion.

The grommet is designed for use in systems operating within a temperature range of -20°C to +120°C. It is ideal for applications involving hot water, steam, inert gases, and chemical media. The combination of press and threaded connections allows for flexibility in system design and integration with various pipe layouts and access points.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN80.2210
Brand	IVAR

The nominal pressure rating of PN 16 indicates the maximum allowable working pressure at standard conditions. The operating temperature range from -20°C to +120°C ensures suitability for both cold and hot media. These parameters are essential for correct sizing and selection in accordance with system design requirements and safety standards.

Installation and connection

To install the grommet, ensure that the press pipe is correctly sized and prepared. Use a calibrated pressing tool to compress the grommet onto the pipe, ensuring the indicator mark aligns with the tool’s stop point. For the threaded side, apply a suitable sealing compound or tape to the male thread before screwing it into the female fitting. Check for alignment and torque according to the manufacturer’s specifications. Common installation errors include insufficient pressing depth, incorrect tool calibration, and over-tightening of the threaded connection. Always verify the seal integrity after installation by inspecting for leaks under operating pressure.

Compatibility and accessories

This grommet is compatible with press-fitted stainless steel pipes and standard Rp threads. Ensure that all mating components are from the same system to maintain sealing performance and mechanical integrity. Accessories such as sealing compounds and pressing tools should be selected according to the manufacturer’s recommendations.

Technical background for designers

The grommet functions as a transitional coupling between press and threaded systems. The stainless steel body provides high resistance to corrosion and thermal stress, making it suitable for long-term operation in aggressive environments. The EPDM O-ring ensures a flexible and durable seal that accommodates minor misalignments and vibrations. When integrated into a system, the grommet supports the structural stability of the piping network and contributes to the overall efficiency of fluid transfer. Designers should consider the thermal expansion characteristics of the materials and the mechanical stresses induced by system pressure and temperature fluctuations. Proper support and spacing of the piping can help reduce stress on the grommet and extend its service life.

Service and operation

No regular maintenance is required for this component under normal operating conditions. However, periodic visual inspections are recommended to detect signs of wear, corrosion, or leakage. In case of suspected failure, isolate the system and inspect the connection for damage or misalignment. Replace the grommet if any deformation or seal degradation is observed.
