Crossing 28 x 22 x 28 x 22

Product detailed description

This 90° cross fitting is used in closed pressurized systems for heating, fire suppression, refrigeration and industrial piping. It is suitable for installations where multiple branch connections are needed at right angles. The fitting is commonly used in central heating systems, cold water circuits, fire water lines and air-conditioning systems. It is designed for environments with fluctuating temperatures and high-pressure demands, ensuring reliable performance in both residential and commercial buildings.

Its compact dimensions and lightweight make it suitable for tight spaces and complex layouts. The fitting is not certified for potable water but is ideal for non-drinking water and inert gas systems. It is used with press-fit connections, eliminating the need for welding or threading. The EPDM O-ring ensures a leak-tight seal when properly installed.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.186 kg
Code	IVC45.2822
Brand	IVAR

The operating temperature range from -20°C to +120°C allows the fitting to be used in both cold and hot environments. The PN16 rating means it can handle pressures up to 16 bar, making it suitable for high-pressure systems. These parameters are essential for selecting the correct component in accordance with the system's hydraulic and thermal requirements.

Installation and connection

The fitting is installed using press-fit tools compatible with M-type jaws. The connection sizes are 28 mm, 22 mm, 28 mm and 22 mm, with all connections being press-fit. The installer must ensure the O-ring is correctly seated and the molding indicator is fully engaged during installation. Common mistakes include using incorrect tools, which can damage the fitting, or failing to check the molding indicator after pressing. Always verify the fit before proceeding with system commissioning.

Compatibility and accessories

The fitting is compatible with IVAR press-fit pipes and fittings of the same material and pressure rating. It is designed to be used with EPDM O-rings and press-fit tools. No additional surface coatings or limiting agents are required. Installers should ensure that all components in the system are from the same manufacturer and pressure class to maintain system integrity. No related products are listed for this model.

Technical background for designers

The 90° cross is made from carbon galvanized steel, providing good corrosion resistance and mechanical strength. The EPDM O-ring ensures a leak-tight seal and is resistant to a wide range of temperatures and media. The fitting is designed for integration into pressurized systems, where it can handle high pressures and thermal expansion. The service life is influenced by the quality of installation, the media being transported and the system's operating conditions. It is suitable for use with dry air, inert gases, and non-potable water.

Service and operation

No regular maintenance is required for this fitting. The system should be inspected for leaks during commissioning and after any modifications. The molding indicator should be checked to ensure the connection remains secure. If a leak is detected, the fitting should be replaced. The fitting is not designed for disassembly and should not be reused once removed.
