Grommet - male thread - N- 22mm-R3/4" IVAR.IVN81

Product detailed description

This press-to-thread transition fitting is commonly used in residential and commercial buildings for connecting press systems to threaded components. It is frequently found in heating circuits, fire suppression systems, and industrial piping. Installers working with mixed systems requiring both press and threaded connections will benefit from this reliable transition solution.

The fitting enables direct mechanical coupling between a 22mm press pipe and a 3/4 inch threaded component. It is designed for use with press tools compatible with the IVAR system. The sealing mechanism relies on an EPDM O-ring compressed during the pressing process. The stainless steel construction ensures long-term resistance to corrosion in wet environments.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN81.2234
Brand	IVAR

The nominal pressure rating of PN 16 indicates the fitting is suitable for medium-pressure systems. The operating temperature range from -20 °C to +120 °C makes it suitable for most heating and hot water applications. These parameters are essential when selecting fittings for specific system requirements.Installation and connection To install, first ensure the 22mm press pipe is cut cleanly and free from burrs. Insert the pipe into the fitting until it reaches the stop mark. Use a calibrated press tool to apply the required force until the indicator shows full compression. Verify the sealing ring is properly seated and the pipe length is within the 54 mm marking range. Common mistakes include using incorrect pressing tools, insufficient pipe insertion, or failing to check the sealing ring position before pressing.

Compatibility and accessories

This fitting is compatible with standard 22mm press pipes and components with a 3/4 inch male thread. Ensure the press pipe is from a compatible system and the thread side is compatible with the mating component. No additional accessories are required for basic installation.

Technical background for designers

The fitting operates by mechanically compressing the press sleeve around the pipe wall, creating a leak-tight seal reinforced by the EPDM O-ring. The 1.4404 stainless steel provides high corrosion resistance, making it suitable for aggressive media in heating and industrial systems. Proper alignment and correct pressing force are critical to maintaining system integrity and preventing premature failure.

Service and operation

Routine inspection should focus on checking for leaks at the connection points and ensuring the system pressure remains within the PN 16 limit. No scheduled maintenance is required under normal operating conditions. If a leak is detected, the fitting should be replaced immediately to avoid system downtime.

Frequently asked questions

Can this fitting be used in solar thermal systems?
Yes, the temperature range supports solar applications as long as the maximum operating temperature does not exceed +120 °C.

Is this fitting suitable for gas applications?
Only if the gas is inert and the system pressure and temperature remain within the specified limits.

Can it be used with copper press pipes?
Yes, provided the copper pipe is compatible with the press tooling and the system requirements match the fitting's parameters.
