Arch 45° MF, 18 x 18

Product detailed description

Press fittings like the IVAR IVC23.18 are commonly used in closed pressurised systems for central heating, fire protection, refrigeration and industrial air systems. Installers working on residential, commercial or industrial buildings often use these components to create leak-free joints without the need for welding or threading. The 45° elbow allows for directional changes in piping layouts, particularly in tight spaces or where gradual turns are required to maintain system efficiency and reduce turbulence. The fitting is suitable for both hot and cold water systems, as well as for dry air and inert gas applications in industrial environments.

Its compact size and lightweight design make it ideal for installations where space is limited and where the system must remain aesthetically clean. The fitting is commonly used in closed-loop systems such as underfloor heating, solar thermal systems and air conditioning ducting. It is also suitable for fire suppression systems where high-pressure resistance is essential. The EPDM sealing ring ensures compatibility with a range of fluids and gases, and the absence of surface coatings means it can be used in environments where chemical resistance is important.

The operating temperature range and pressure rating are key factors in determining the suitability of the fitting for a specific application. The -20 °C to +120 °C range allows for use in both cold and hot systems, while the 16 bar pressure rating ensures it can handle high-pressure environments such as fire suppression or industrial air systems. These parameters are essential for sizing and selecting the correct component for the system's operational conditions.Installation and connection The IVAR IVC23.18 is installed using a press tool compatible with Type M jaws. The fitting has one press end and one plug-in end, which allows for quick assembly without the need for additional tools. The press operation must be performed with the molding indicator visible to ensure a complete and secure connection. Installers should verify that the pipe ends are clean and free from burrs before pressing. A common mistake is not aligning the fitting correctly, which can lead to leaks or reduced system performance. It is also important to ensure that the press tool is set to the correct depth and that the molding indicator is fully engaged to confirm a successful connection.

Compatibility and accessories

The fitting is compatible with a wide range of IVAR press pipe systems and can be integrated into existing pressurised systems without the need for additional adapters or transitions. It is suitable for use with carbon galvanized steel pipes and requires no additional surface treatment. When installing, ensure that the correct size and type of press tool is used. No additional surface coating agents or lubricants are required for the connection. The fitting is not certified for drinking water applications and should not be used in systems where potable water is present.

Technical background for designers

The IVAR IVC23.18 is a 45° elbow designed for use in pressurised systems. It is made from carbon galvanized steel, which provides good corrosion resistance and mechanical strength. The EPDM O-ring ensures a tight seal and is compatible with a range of fluids and gases. The press connection method eliminates the need for welding or threading, reducing installation time and potential for errors. The fitting is suitable for integration into closed-loop systems where high-pressure resistance and thermal stability are required. The operating temperature and pressure ratings are determined by the material properties and the design of the press connection, which ensures long-term reliability and performance.

Service and operation

The fitting requires no regular maintenance under normal operating conditions. However, it is important to periodically inspect the system for leaks or signs of wear, particularly at the press connections. If a leak is detected, the fitting should be replaced immediately. The absence of surface coatings means that the fitting is not prone to degradation from chemical exposure, but it should not be used in environments where the media is corrosive to carbon steel. The press connection is designed to be permanent and should not be disassembled unless the system is decommissioned.
