Crossing 28 x 18 x 28 x 18

Product detailed description

This 90° cross fitting is designed for use in pressurised systems such as central heating, fire suppression, and industrial piping. It is commonly used in closed-loop systems where leak-free connections are essential. The fitting is suitable for both new installations and system modifications, particularly in environments requiring resistance to high pressure and a wide temperature range. It is often found in commercial and industrial buildings, including those with solar heating systems, refrigeration circuits, and air-conditioning installations.

Technical parameters

Material	Carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.166 kg
Code	IVC45.2818
Brand	IVAR

The operating temperature range of -20°C to +120°C allows the fitting to be used in both cold and hot water systems. The PN 16 rating means it can handle pressures up to 16 bar, making it suitable for high-pressure applications. The material, carbon galvanized steel, ensures durability and resistance to corrosion in non-drinking water and industrial environments.

Installation and connection

The fitting connects via press connections, requiring compatible M-type jaws for secure assembly. The dimensions are 28 x 18 x 28 x 18 mm, and all connections are press type. During installation, ensure the O-ring is correctly seated and the molding indicator is visible after pressing. Common mistakes include using incorrect jaw types or failing to verify the molding indicator. Always check for internal alignment and ensure the system is depressurised before installation.

Compatibility and accessories

This cross is compatible with other IVAR press fittings and pipes within the same system. It is suitable for use with EPDM O-rings and should be used with M-type pressing tools. No additional accessories are required for standard installation, but ensure the system includes compatible press tools and sealing materials.

Technical background for designers

The fitting operates by forming a mechanical and hydraulic seal through the press connection. The carbon galvanized steel body provides structural integrity, while the EPDM O-ring ensures a tight seal. The fitting is designed for integration into closed systems where high pressure and temperature resistance are required. The service life is influenced by the quality of the press connection and the operating conditions, including media type and temperature fluctuations.

Service and operation

No regular maintenance is required for this fitting. However, during system inspections, check for signs of leakage or wear at the press connections. The molding indicator should remain visible as a confirmation of a secure connection. If any issues arise, the fitting should be replaced and repressed using the correct tools.
