Arch 90°, 35 x 35

Product detailed description

Press-fit 90° arcs like the IVAR IVC70.35 are essential components in closed-loop heating systems, fire suppression, and industrial air or gas distribution. They are commonly used in residential, commercial, and industrial buildings where reliable, leak-free connections are required. Installers working on central heating ducts, refrigeration circuits, or solar system piping will find this fitting suitable for its mechanical strength and resistance to high pressures. The fitting is particularly useful in applications where welding is not feasible or where rapid assembly is required without compromising system integrity.

Correct selection of press-fit components is critical for system performance. The IVAR IVC70.35 is designed for use in press-fit systems with Type M jaws, ensuring a secure connection without the need for threading or welding. Its galvanized carbon steel construction provides durability and resistance to corrosion in non-drinking water environments. The arc is suitable for both pressurised and non-pressurised systems, provided the operating conditions remain within the specified limits.

Technical parameters

Code	IVC70.35
Brand	IVAR

The operating temperature range of -20 °C to +120 °C makes this arc suitable for cold and hot water systems, as well as industrial applications involving dry air or inert gases. The nominal pressure rating of PN 16 means it can handle up to 16 bar, which is important for sizing the component correctly in high-pressure circuits. These parameters are crucial for ensuring the arc can withstand the mechanical and thermal stresses of the system it is installed in.

Installation and connection

The IVAR IVC70.35 is installed using a press tool compatible with Type M jaws. The fitting is designed for 35 mm diameter pipes, and the press operation must be performed according to the manufacturer's guidelines to ensure a leak-free connection. During installation, the press tool must be aligned correctly with the fitting to avoid misalignment or incomplete pressing. A common mistake is failing to check the molding indicator, which confirms the press has been completed properly. If the indicator is not fully engaged, the joint may not be secure and could lead to leaks under pressure.

Compatibility and accessories

This 90° arc is compatible with other components in the IVAR.IVC70 range, including straight pipes, elbows, and tees of the same diameter. For installation, a press tool and Type M jaws are required. No additional surface coatings or limiting agents are needed, as the fitting is designed for direct pressing without the need for lubricants or sealants. It is important to ensure that all components in the system are from the same press-fit range to maintain compatibility and system integrity.

Technical background for designers

The IVAR IVC70.35 is a long-radius 90° arc made from carbon galvanized steel, which provides good resistance to mechanical damage and corrosion in non-drinking water environments. The press-fit connection relies on a mechanical deformation of the fitting and pipe wall to create a tight seal. This method eliminates the need for welding or threading, reducing installation time and the risk of thermal distortion. The operating temperature range and pressure rating are key factors in determining the suitability of the component for a given system. The long service life of the fitting is influenced by the quality of the press operation and the absence of mechanical stress during installation.

Service and operation

The IVAR IVC70.35 requires no regular maintenance beyond routine system checks. During operation, it is important to ensure that the system pressure does not exceed the rated 16 bar and that the temperature remains within the specified range. Any signs of leakage or deformation should be investigated immediately, as these may indicate a faulty press connection or material fatigue. The absence of surface coatings or sealants means that the fitting is not suitable for environments where chemical exposure could accelerate corrosion.
