Arch 90° - N - 54mm IVAR.IVN20

Product detailed description

This 90° elbow is commonly used in heating systems, sanitary installations, fire suppression systems, solar applications, and industrial piping. It connects press-fit stainless steel pipes using a reliable compression seal. Installers working on residential and commercial buildings will find this fitting suitable for applications requiring resistance to corrosion and high temperatures.

The design ensures compatibility with press-fit stainless steel piping systems. It is especially suited for environments where thermal expansion and contraction occur frequently, such as in underfloor heating or solar water heating systems. The fitting is non-leaching and suitable for potable water systems when specified.

Technical parameters

Installation and connection

The IVN20.54 is installed using a press tool compatible with stainless steel press-fit systems. The connection requires a clean and straight pipe end, free from burrs or debris. The fitting features an indicator to confirm correct insertion depth into the 54 mm dimension. After pressing, the tool must fully compress the ferrule against the pipe wall to form a tight seal.

Installers should verify that the pipe is correctly aligned before pressing and ensure the O-ring is seated properly. Common installation errors include insufficient pressing force, misalignment during installation, or using a damaged ferrule. Always follow the manufacturer’s guidelines for the press tool and confirm the fit using the visual indicator provided.

Compatibility and accessories

This fitting is compatible with stainless steel press-fit pipes of the same diameter and system. For complete system integrity, it should be used with press tools and ferrules specifically designed for IVAR stainless steel piping. Additional components such as straight couplings or other elbows may be required depending on the layout of the installation.

Technical background for designers

The elbow operates by redirecting the flow of fluids or gases in a 90° direction without introducing turbulence or pressure loss. The stainless steel material offers high resistance to corrosion and thermal cycling, making it ideal for long-term use in aggressive environments. The EPDM O-ring ensures a flexible yet durable seal, compensating for minor misalignments and thermal expansion. The fitting integrates seamlessly into closed-loop systems, such as underfloor heating or solar collectors, where consistent flow and pressure are critical.

The service life of the fitting depends on the quality of the installation, the accuracy of the press tool, and the conditions within the system. Proper alignment and pressing are crucial to avoid premature failure due to stress points or leakage. The material properties also help maintain system efficiency by reducing energy loss through heat transfer or flow resistance.

Service and operation

During regular system checks, inspect the fitting for signs of leakage, corrosion, or mechanical damage. While the stainless steel construction requires no routine maintenance, any visible deformation or damage should be addressed immediately. There are no defined service intervals for this component unless specified in the system’s operational manual.

Frequently asked questions

Can the IVN20.54 be used with copper pipes?
No, this fitting is specifically designed for stainless steel press-fit systems and is not compatible with copper piping.

What is the maximum allowable temperature for continuous operation?
The maximum continuous operating temperature is +85 °C, with a short-term limit of +120 °C.

Is the EPDM O-ring resistant to chemicals?
Yes, the EPDM O-ring provides good resistance to many common chemicals and is suitable for use in both heating and industrial applications.

Can the fitting be reused after disassembly?
No, once the fitting has been pressed, it cannot be reused. A new fitting must be installed if the connection is broken or removed.
