Arch 90°, 18 x 18

Product detailed description

This 90° curved arc is commonly used in the installation of central heating, refrigeration, fire suppression, and industrial piping systems. It is particularly suited for applications involving closed pressurised systems, such as those found in residential, commercial and industrial buildings. Installers working on HVAC, solar thermal or dry-air systems will find this component ideal for creating precise 90° bends without the need for welding or threading. The design supports a wide range of working conditions and integrates easily into existing infrastructure.

Typical installation scenarios include central heating distribution, fire water supply lines, and refrigeration circuits. The material and construction allow for long-term reliability in both high and low-temperature environments. Its lightweight design also simplifies handling and reduces installation time.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.082 kg
Code	IVC70.18
Brand	IVAR

The operating temperature range ensures suitability for both heating and cooling applications. The pressure rating of PN 16 allows the fitting to handle up to 16 bar, which is essential for accurate system sizing and selection in pressurised environments. These parameters are crucial when matching the component to the hydraulic requirements of the system.

Installation and connection

To install the 90° arc, ensure the pipe ends are clean and free of debris. Use a press tool compatible with M-type jaws for secure crimping. Check that the crimp indicator is properly engaged during the process. The connection size is standardised to 18 mm diameter. Common mistakes include insufficient crimp depth, misalignment during pressing, or using incompatible tools. Always verify the fit and crimp quality before proceeding to the next section of the system.

Compatibility and accessories

This 90° arc is compatible with other components in the IVAR.IVC70 series, including straight pipes, elbows and tees of the same nominal diameter. For installation, press tools with M-type jaws and a crimp indicator up to 54 mm are required. No additional sealing materials are needed due to the integrated crimp design. Ensure all tools and accessories are from the same manufacturer to maintain system integrity.

Technical background for designers

The arc is manufactured from carbon galvanized steel, offering good corrosion resistance and mechanical strength. Its press-fit design eliminates the need for soldering or threading, reducing installation time and potential leaks. The material is suitable for closed-loop systems and can be integrated with various piping materials. Longevity and performance depend on correct installation, adherence to pressure and temperature limits, and avoiding exposure to aggressive media outside the specified parameters.

Service and operation

No routine maintenance is required for this component under normal operating conditions. During service checks, inspect the crimped joints for signs of wear or leakage. Ensure the system pressure remains within the stated limits. If operating near the maximum temperature or pressure thresholds, perform more frequent visual inspections to confirm structural integrity.

Frequently asked questions

Can the IVC70.18 be used in solar thermal systems?
Yes, the arc is suitable for solar piping systems as long as the operating temperature does not exceed +120 °C and the pressure remains within the rated limit of 16 bar.

Is this component compatible with other press systems?
It is specifically designed for use with IVAR press tools and M-type jaws. Using non-compatible tools may compromise the integrity of the connection.

Can the fitting be used for dry air or inert gas applications?
Yes, it is suitable for dry air and inert gas systems provided the operating conditions remain within the specified temperature and pressure limits.

What should be checked after installation?
After installation, verify the crimp depth and alignment using the tool’s indicator. Visually inspect the joint for deformation or misalignment to ensure a secure connection.
