Arc 45° - N - 42mm IVAR.IVN22

Product detailed description

This 45° press elbow is commonly used in heating systems, industrial installations, and technical buildings where directional changes in piping are required. It connects two pipes at an angle using press technology, ensuring leak-free connections under varying thermal conditions. Installers working on central heating circuits, solar systems or fire protection installations will find this fitting suitable for integration into closed-loop systems with fluid media such as water or inert gases.

The elbow is designed for environments with fluctuating temperatures, making it ideal for both indoor and outdoor installations where mechanical durability and corrosion resistance are essential. It supports the routing of pipes around structural elements and ensures alignment precision during press fitting.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM sealing ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN22.42
Brand	IVAR

This elbow operates within a temperature range from -20 °C to +85 °C, with a maximum allowable temperature of +120 °C. The nominal pressure rating of PN 16 indicates suitability for medium-pressure applications. These parameters guide the selection of fittings in accordance with system requirements and media properties.

Installation and connection

To install the press elbow, ensure both pipe ends are clean and free from burrs. Use a calibrated press tool compatible with the fitting’s dimensions. Confirm the correct positioning of the sealing ring and press until the indicator reaches the specified depth. Check for visual alignment and press depth indicators to avoid incomplete pressing. Common errors include over-pressing or misalignment, which can compromise the seal and lead to leakage.

Compatibility and accessories

This fitting is compatible with press-ended stainless steel pipes of corresponding diameters. For full system integrity, use with press tools and gauges certified for this type of fitting. Ensure all adjacent components have matching press connection standards and sealing ring materials for consistent performance.

Technical background for designers

The elbow is manufactured from 1.4404 (AISI 316L) stainless steel, offering high resistance to corrosion and thermal stress. Its EPDM sealing ring provides flexibility and maintains tightness under thermal expansion. Integration into the system requires consideration of flow dynamics and directional changes. System efficiency depends on proper alignment and accurate press fitting to prevent pressure loss or flow restriction.

Service and operation

Periodic inspection should focus on the integrity of the press joint and signs of wear or corrosion. In case of suspected leakage, re-pressing may be possible provided the material has not been overstressed. Avoid repeated pressing attempts on the same fitting as it can weaken the joint.

Frequently asked questions

Can the elbow be used in solar heating systems?
Yes, it is suitable for solar systems due to its ability to handle elevated temperatures and thermal cycling.

Is the elbow compatible with copper press pipes?
No, it is specifically designed for stainless steel press systems and must not be used with copper or other incompatible materials.

What is the function of the EPDM sealing ring?
The sealing ring ensures a tight connection by compensating for minor dimensional variations and providing a flexible barrier against fluid leakage.

Can the elbow be used for gas applications?
It is approved for inert gas systems but must not be used with flammable or reactive gases unless confirmed by the system design specifications.
