Arch 45° FF, 88.9 x 88.9

Product detailed description

Press fittings like the Arch 45° FF are essential components in closed pressurised systems, including central heating, refrigeration, fire suppression, and industrial air or gas distribution. Installers and technicians working in commercial or industrial buildings often use such fittings to create leak-free, durable joints without the need for welding or threading. The elbow is suitable for both indoor and outdoor applications, provided the system is designed for pressurised operation. It is particularly useful in systems where space constraints require angled connections and where high mechanical strength and resistance to environmental stress are required.

This fitting is commonly used in HVAC ductwork, solar system piping, and fire water supply systems. The press connection method ensures a secure and reliable joint, which is critical in systems where pressure integrity is essential. The elbow must be installed using compatible Type M jaws and a press tool to ensure the molding indicator is fully engaged. The absence of surface coating limiting agents means the fitting can be used in systems where chemical compatibility is a concern.

Technical parameters

Material	carbon galvanized steel
Operating temperature	-20 °C
Nominal pressure	PN 16
Resistance to high pressures up to	16 bar
Weight	1.084 kg
Code	IVC22.89
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 in environments with fluctuating temperatures. The maximum pressure rating of 16 bar ensures it is suitable for high-pressure applications such as fire suppression or industrial gas systems. These parameters are essential for correct system sizing and component selection, particularly in pressurised closed-loop systems where pressure and temperature fluctuations are expected.

Installation and connection

The Arch 45° FF is installed using a press tool compatible with Type M jaws. The connection size is 88.9 mm, and the fitting must be aligned with the pipe before pressing. The molding indicator must be fully engaged to confirm a successful connection. Installers should verify that the pipe is clean and free of burrs before pressing. Common installation mistakes include using incorrect jaws, failing to align the fitting, or pressing without confirming the molding indicator. These errors can lead to leaks or joint failure under pressure.

Compatibility and accessories

This fitting is compatible with other IVAR press components and systems using carbon galvanized steel piping. For complete system integration, ensure that all components are press-compatible and that the correct press tool and jaws are available. No additional surface coatings or agents are required, but the EPDM O-ring must be intact for a proper seal. Related products include straight press fittings, bends, and tees from the same IVAR IVC22 range.

Technical background for designers

The fitting operates by forming a mechanical and hydraulic seal between the pipe and the fitting through the press tool. The carbon galvanized steel provides high strength and corrosion resistance, while the EPDM O-ring ensures a tight seal across a wide temperature range. The fitting is designed for integration into closed systems where pressure and temperature stability are important. The service life and efficiency depend on correct installation, system pressure, and environmental conditions such as exposure to moisture or chemicals.

Service and operation

No specific maintenance is required for the Arch 45° FF during normal operation. However, installers should periodically inspect the joint for signs of wear, corrosion, or leakage, particularly in high-pressure or high-temperature environments. If any issues are detected, the fitting should be replaced. There are no defined service intervals in the technical data provided.

Frequently asked questions

Can the Arch 45° FF be used in solar water heating systems?
Yes, the fitting is suitable for solar system piping as it is rated for temperatures up to +120 °C and can handle pressurised water.

Is the fitting compatible with inert gas systems?
Yes, the fitting is suitable for use with inert gases, provided the system is pressurised and the gas is non-corrosive.

Can the fitting be used in fire suppression systems?
Yes, the fitting is suitable for fire water supply systems due to its high pressure rating and resistance to mechanical damage.

Can the fitting be used with copper pipes?
No, the fitting is designed for use with carbon galvanized steel pipes and is not compatible with copper.
