Faced arch 90° - N - 35mm IVAR.IVN70

Product detailed description

This 90° stainless steel press-fitting elbow is commonly used in heating systems, medical equipment, fire sprinkler systems, compressed air installations, solar systems and industrial applications. It connects press-fit pipes to threaded components using a reliable, leak-tight connection. The elbow is designed for use in environments requiring high corrosion resistance and durability, such as chemical processing plants, hospitals and industrial facilities. It ensures smooth fluid flow and is suitable for both new installations and system upgrades.

Its stainless steel construction allows for long-term performance in aggressive media and varying temperatures. The elbow is typically installed by pressing the pipe into the fitting and then securing it with a threaded connection. It is particularly suited for applications where a combination of mechanical and hydraulic integrity is required, such as in closed-loop systems or high-pressure environments.

Technical parameters

Installation and connection

The elbow is installed using a press tool to connect the stainless steel pipe to the fitting. The internal thread allows for secure connection to other threaded components. Before installation, ensure the pipe is correctly sized and free from damage. Apply the press tool until the indicator confirms a complete seal. After pressing, check the alignment of the fitting and verify that the thread is clean and undamaged. Common errors include insufficient pressing depth, misalignment and failure to inspect the O-ring for wear.

Compatibility and accessories

This elbow is compatible with stainless steel press-fit piping systems and components with matching internal threading. It is typically used in conjunction with press-fit pipes of the same material and size. Additional components such as sealing rings and press tools are required for installation. Ensure all parts are from the same system to maintain compatibility and prevent leaks.

Technical background for designers

Constructed from stainless steel grade 1.4404 (AISI 316L), the elbow offers high resistance to corrosion and thermal expansion. Its EPDM O-ring provides a flexible seal that maintains integrity under varying temperatures and pressures. The design integrates into both closed-loop and open systems, supporting efficient flow with minimal turbulence. Longevity depends on proper installation, correct system pressure and media compatibility.

Service and operation

Regular inspection is recommended to ensure the integrity of the press connection and the condition of the O-ring. Check for signs of leakage, especially after installation or during system maintenance. No specific service intervals are provided in the technical data. If any issues arise, disassemble the fitting, inspect for wear and replace damaged components as necessary.

Frequently asked questions

Can the IVN70.35 be connected to copper pipes?
No, the fitting is designed for stainless steel press-fit piping only and should not be used with copper or other incompatible materials.

Is this elbow suitable for high-pressure steam applications?
Yes, provided the operating pressure does not exceed PN16 and the temperature remains within the specified range of -20°C to +120°C.

Can the IVN70.35 be used in medical gas systems?
Yes, the elbow is suitable for medical gas systems due to its high-grade stainless steel and EPDM sealing ring, which meet hygiene and purity requirements.

Does the press depth indicator apply to all pipe lengths?
Yes, the press depth indicator is valid for pipe lengths up to 54 mm. For longer lengths, follow the manufacturer’s guidelines for pressing depth.
