Arch 45° - with one plug-in end - N - 108mm IVAR.IVN23

Product detailed description

The IVAR IVN23.108 45° elbow is commonly used in heating, ventilation, and industrial piping systems where directional changes are required. This fitting is frequently installed in residential and commercial buildings, including hospitals, schools, and industrial facilities. It enables efficient routing of fluids such as water, steam, and inert gases in closed-loop systems. Installers working on sanitary, fire suppression, or solar thermal systems will find this elbow suitable for both new builds and retrofit projects.

Its design allows for integration into press-fit systems, where it connects to copper or stainless steel pipes via a mechanical pressing tool. The single push-fit end ensures ease of assembly while maintaining a leak-tight seal. This fitting is particularly useful in tight spaces or complex layouts where multiple directional changes are necessary. The elbow’s robust construction supports long-term reliability in environments subject to fluctuating temperatures and pressures.

Technical parameters

Installation and connection

Installation begins by preparing the pipe ends with a suitable cutting and deburring tool. The push-fit end of the elbow is inserted onto the pipe until the stop mark is reached. A pressing tool is then used to compress the fitting around the pipe, creating a secure, leak-tight joint. It is important to verify that the pressing tool is correctly aligned and calibrated to avoid under- or over-pressing, which can compromise the seal.

• Check that the pipe is clean and free of burrs before insertion.
• Ensure the elbow is fully seated against the stop mark on the pipe.
• Use only manufacturer-approved pressing tools and dies to avoid damage to the fitting.
• After pressing, inspect the indicator ring to confirm proper compression.

Compatibility and accessories

This 45° elbow is designed for use with IVAR press-fitting systems and is compatible with stainless steel and copper pipes of appropriate diameter. For complete system integration, additional components such as straight pipes, other elbows, and valves may be required. Installers should ensure that all fittings and pipes are from the same system to maintain compatibility and performance standards.

Technical background for designers

The IVAR IVN23.108 45° elbow operates on the principle of mechanical compression, where the press-fit connection forms a metal-to-metal seal reinforced by an EPDM O-ring. Its integration into a system depends on accurate hydraulic calculations to ensure flow rates and pressure drops remain within acceptable limits. The elbow’s longevity is influenced by factors such as fluid quality, system cleanliness, and the frequency of thermal cycling.

Service and operation

During operation, it is important to monitor the system for signs of leakage or pressure loss. While no routine maintenance is typically required for this type of fitting, periodic visual inspections can help identify potential issues early. If a leak occurs, the affected section should be isolated and the fitting replaced. No specific service intervals are provided in the technical documentation, so maintenance should be carried out as needed based on system performance and inspection results.

Frequently asked questions

Can the IVN23.108 be used in solar thermal systems?
Yes, it is suitable for solar thermal applications due to its resistance to high temperatures and thermal cycling.

Is the elbow compatible with copper pipes?
Yes, it can be connected to copper pipes using the press-fit method as long as the pipe diameter matches the fitting’s specifications.

What is the maximum allowable temperature during operation?
The maximum operating temperature is +120 °C, as specified in the technical data.

Can the elbow be used in fire suppression systems?
Yes, it is approved for use in fire suppression systems where press-fit stainless steel components are required.
