Connection fitting - internally threaded - N - 22mm-Rp3/4" IVAR.IVN62

Product detailed description

Internally threaded connection fittings are essential components in the installation of heating, plumbing and industrial systems. They provide secure and leak-free connections between press-fit pipes and threaded components. This type of fitting is commonly used in residential and commercial buildings for connecting pipe systems to valves, meters and other threaded devices. Installers frequently encounter these fittings in systems such as hot and cold water supply, heating circuits, and fire protection systems. The correct selection and installation of the fitting ensures long-term reliability and system integrity.

When working with such fittings, the installer must ensure the correct alignment and pressing depth to achieve a watertight connection. The sealing properties depend on proper pressing and the condition of the sealing ring. Inaccurate pressing or using damaged components can lead to leaks and system failure. These fittings are often part of larger pipe networks and must be selected according to the system's pressure and temperature requirements.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN62.2234
Brand	IVAR

The nominal pressure rating of PN 16 indicates that the fitting is suitable for systems operating under moderate pressure conditions. The operating temperature range allows use in both cold and hot water applications. These parameters are critical for determining the suitability of the fitting for specific system designs and ensuring compatibility with other components in the network.

Installation and connection

To install the fitting, the press-fit end should be connected to a compatible pipe using a suitable pressing tool. The internal thread is designed for direct connection to Rp3/4" components. Before pressing, ensure the pipe end is clean and free of burrs. After pressing, verify that the pressing depth indicator is correctly engaged and that the fitting is fully seated. Common installation errors include insufficient pressing depth, misalignment, and using incompatible tools. Always check the system for tightness after installation by performing a pressure test.

Compatibility and accessories

The fitting is compatible with standard press-fit stainless steel pipes of appropriate diameter and with any device featuring an Rp3/4" thread. For complete installation, additional components such as press tools, sealing rings and threaded accessories may be required. Related products include other press fittings from the IVAR IVN62 series, which offer similar performance and dimensions.

Technical background for designers

This connection fitting operates by forming a mechanical and hydraulic seal through the pressing process. The stainless steel body provides high resistance to corrosion and wear, making it suitable for long-term use in aggressive environments. The EPDM sealing ring ensures flexibility and durability under varying temperature conditions. When integrating the fitting into a system, consider the thermal expansion of the piping material and the pressure distribution across the network. The material properties and design of the fitting contribute to the overall efficiency and longevity of the system.

Service and operation

During operation, the fitting requires no regular maintenance. However, periodic inspections are recommended to detect potential leaks or signs of wear. If a leak occurs, the fitting should be removed and replaced with a new one. There are no specified service intervals for this component, as it is designed for long-term use under normal operating conditions.

Frequently asked questions

Can this fitting be used in solar heating systems?
Yes, the fitting is suitable for use in solar heating systems due to its resistance to temperature variations and compatibility with hot water.

Is the sealing ring replaceable?
The sealing ring is integrated into the fitting and is not designed for separate replacement. A new fitting must be installed if the seal is damaged.

What is the maximum allowable operating temperature?
The fitting can operate at a maximum temperature of +120 °C, making it suitable for hot water and heating applications.

Can the fitting be used with copper pipes?
No, the fitting is specifically designed for use with stainless steel press-fit pipes and is not compatible with copper piping systems.
