Arch 45° FF, 108 x 108

Product detailed description

This 45° press elbow is commonly used in closed heating systems, fire water supply systems, refrigeration ductwork and industrial air conditioning. It is designed for use in environments where high-pressure resistance and a wide temperature range are required. The fitting is suitable for installation in both residential and commercial buildings, including systems where dry air, inert gases or non-potable water are transported. The press connection eliminates the need for welding or threaded joints, making it ideal for installations where speed and safety are critical.

Typical applications include central heating ducts in pressurised systems, fire suppression ducts, and air conditioning ducts. The fitting is also used in solar system piping and refrigeration systems. It is not certified for drinking water applications and must be installed in accordance with the system’s pressure and temperature limits.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	1.61 kg
Code	IVC22.108
Brand	IVAR

The operating temperature range from -20°C to +120°C makes this fitting suitable for both cold and hot systems. The PN16 rating means it can handle pressures up to 16 bar, which is essential for high-pressure environments such as fire suppression systems. The material selection ensures compatibility with non-potable water, dry air and inert gases, but not with drinking water. These parameters are critical for correct sizing and system integration.

Installation and connection

The fitting uses a press connection method and is compatible with Type M jaws. The press connection requires the use of a suitable press tool and must be performed according to the manufacturer’s instructions. The connection size is 108 mm, and the fitting must be aligned precisely to avoid misalignment and leakage. During installation, it is important to ensure that the molding indicator is fully engaged and that the joint is visually inspected for proper sealing. Common installation errors include using incorrect tools, insufficient press force or misalignment of the fitting and pipe.

Compatibility and accessories

This fitting is compatible with other IVAR press fittings and pipes in the same system. It is designed to work with EPDM O-rings and must be used with carbon galvanized steel pipes. No additional surface coating or limiting agents are required. For larger systems, additional fittings such as couplings, tees and elbows may be needed. Accessories such as press tools and Type M jaws are required for installation.

Technical background for designers

The fitting operates on a mechanical press connection principle, where the pipe is inserted into the fitting and secured using a press tool. The EPDM O-ring ensures a tight seal and prevents leakage. The carbon galvanized steel material provides resistance to mechanical damage and corrosion in non-potable water and industrial environments. The system must be designed to account for thermal expansion and contraction, especially in systems with large temperature variations. The service life and efficiency of the fitting depend on proper installation, correct press force and the absence of misalignment.

Service and operation

No regular maintenance is required for this fitting. However, during system inspections, the press joints should be visually checked for signs of leakage or damage. If the molding indicator is not fully engaged or if the joint appears loose, the fitting should be replaced. The fitting is not designed for disassembly and reassembly after installation. Any damage to the fitting or O-ring should be addressed immediately to prevent system failure.

Frequently asked questions
