Arc 45° - N - 76,1mm IVAR.IVN22

Product detailed description

Press-fit fittings such as the IVAR IVN22.76 45° elbow are commonly used in mechanical installations requiring reliable and leak-free connections. They are often found in commercial and industrial buildings, including hospitals, factories, and large residential complexes. Installers working on heating circuits, fire suppression systems, and compressed air lines benefit from the ease of installation and robustness of such components. The fitting facilitates directional changes in piping layouts while maintaining system integrity under fluctuating thermal conditions.

This component is particularly useful in applications involving hot water, steam, and inert gases. Its construction allows for use in both closed-loop and open-loop systems, ensuring compatibility with a range of media. The press-fit method eliminates the need for welding or threading, reducing installation time and potential points of failure. When integrated correctly, the fitting contributes to long-term system performance and minimal maintenance requirements.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN22.76
Brand	IVAR

The elbow is rated for nominal pressure PN 16 and can operate within a temperature range from -20 °C up to +120 °C. These parameters are essential for determining whether the fitting is appropriate for a given application. The temperature limit ensures compatibility with typical heating and hot water systems. The pressure rating indicates the maximum allowable stress on the joint under normal operating conditions, which is important when designing pipe networks.

Installation and connection

The IVAR IVN22.76 is installed using a press tool designed for stainless steel press fittings. Each end of the elbow features a pressable zone that must be fully compressed to ensure a tight seal. The internal EPDM O-ring supports the joint’s resistance to leakage. The fitting connects to pipes via standard press-fit interfaces. Prior to pressing, the pipe should be measured and cut cleanly to avoid misalignment during assembly. Installers should verify the presence of the correct O-ring and inspect the fitting for damage or deformation. Common errors include incomplete pressing, misaligned joints, or failure to follow the manufacturer’s pressing depth indicators.

Compatibility and accessories

This fitting is compatible with stainless steel pipes of corresponding dimensions and is typically used alongside straight press-fit tubes and other press fittings. To complete the system, additional components such as straight sections, couplings, and valves may be required. Ensure all parts are sourced from the same manufacturer or certified equivalent to maintain consistent performance standards. While no specific alternative products are listed, similar press elbows from IVAR may be considered based on the required angle and size.

Technical background for designers

The 45° elbow functions by redirecting the flow of fluid or gas through a controlled angular change. The material—1.4404 stainless steel—is selected for its high corrosion resistance and durability in aggressive environments. The EPDM O-ring provides flexibility and airtight sealing under varying thermal expansion rates. The press-fit method relies on mechanical deformation of the fitting’s collar to create a secure joint. System efficiency is influenced by correct alignment, even pressure distribution during pressing, and proper support structures to prevent stress on the joint. Longevity depends on adherence to installation guidelines and avoiding over-tightening or under-pressing.

Service and operation

Routine inspection is recommended to detect signs of wear, corrosion, or loosening of the joint. During servicing, check the integrity of the O-ring and ensure the fitting remains free from mechanical stress caused by pipe movement. There are no scheduled service intervals specified for this component, as it is designed for long-term use without maintenance. In case of suspected leaks, the system should be depressurized and inspected for misalignment or damage to the pressed joint.

Frequently asked questions

Can the IVAR IVN22.76 be used with copper pipes?
No. This fitting is specifically designed for stainless steel press-fit systems and is not compatible with copper or other non-press pipe types.

What is the maximum allowable temperature for continuous operation?
The fitting is rated for continuous operation up to +85 °C, with a short-term maximum of +120 °C.

Is the EPDM O-ring replaceable after installation?
No. The O-ring is sealed inside the fitting during manufacturing and cannot be accessed or replaced once the joint is pressed.

How is the correct pressing depth ensured during installation?
The fitting includes an indicator mark to guide the pressing tool. The tool should compress the fitting until the mark aligns with the stop on the tool.
