Arch 45° FF, 42 x 42

Product detailed description

This 45° press elbow is commonly used in closed pressurised systems such as central heating, fire protection, refrigeration and air-conditioning ductwork. It is suitable for applications involving water, dry air, inert gases and industrial media. The fitting is designed for use in environments where high pressure resistance and a wide temperature range are required. It is often found in commercial and industrial buildings, including those with solar heating systems or pressurised air-conditioning ducts.

Installers working with closed-loop systems benefit from the quick assembly and secure connection provided by the press-fit design. The fitting eliminates the need for welding or threaded joints, reducing installation time and potential leak points. It is particularly useful in systems where aesthetics and mechanical durability are important, such as in exposed ductwork or underfloor heating installations.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	0.21 kg
Code	IVC22.42
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, as well as refrigeration and heating applications. The maximum pressure resistance of 16 bar ensures compatibility with pressurised systems such as fire sprinklers and industrial air-conditioning. The material choice of carbon galvanized steel provides corrosion resistance and mechanical strength, making it suitable for long-term use in demanding environments.

Installation and connection

The IVAR IVC22.42 is installed using a press tool compatible with Type M jaws. The fitting is connected to press-ready pipes with a molding indicator that confirms the successful press operation. The press connection should be made at the specified depth to ensure a secure and leak-free joint. Installers should verify that the molding indicator is fully engaged and that the press tool is correctly aligned with the fitting and pipe. Common installation errors include using an incorrect press tool, insufficient press depth, or failing to check the molding indicator after pressing. Always ensure the system is depressurised and dry before installation.

Compatibility and accessories

This 45° elbow is compatible with other IVAR press fittings and pipes within the same system. It is designed for use with carbon galvanized steel pipes and requires EPDM O-rings for sealing. For installation, a press tool with Type M jaws is required. Additional components such as straight pipes, other elbows and T-junctions may be needed depending on the system layout. No surface coating limiting agents are present, so the fitting can be integrated into systems without concerns about chemical compatibility.

Technical background for designers

The press-fit system relies on a mechanical deformation of the pipe wall to create a secure joint. The EPDM O-ring provides a flexible seal that accommodates minor misalignments and thermal expansion. The carbon galvanized steel construction offers good resistance to corrosion and mechanical damage, making it suitable for both indoor and outdoor applications. The material properties ensure long-term durability in pressurised systems. The operating temperature range and pressure resistance are critical for system design, especially in environments with fluctuating conditions. The fitting is not certified for potable water applications, so alternative materials should be considered for drinking water systems.

Service and operation

During operation, the fitting requires no regular maintenance. However, periodic visual inspections are recommended to check for signs of mechanical damage, corrosion or leaks. The press connection should remain intact and the molding indicator should not show any signs of wear or deformation. If a leak is detected, the affected section should be isolated and the fitting replaced. No specific service intervals are provided, but the system should be monitored for performance and integrity during routine maintenance checks.
