Press fittings stopper - N - 28mm IVAR.IVN51

Product detailed description

Press stoppers are essential components in press-fitting systems used in a variety of technical and industrial installations. They are commonly used in heating systems, plumbing, fire sprinkler systems, and industrial piping to terminate or isolate sections of the system. The IVAR IVN51.28 is designed for use in environments where a secure, leak-tight seal is required under varying thermal and hydraulic conditions. It is particularly suitable for installations where the system is exposed to both low and high temperatures, such as in solar systems or industrial processes involving inert gases.

Installers working in commercial, residential, and industrial sectors will find this stopper ideal for sealing unused pipe ends or for system isolation during maintenance. The stainless steel construction ensures compatibility with a wide range of fluids and media, making it suitable for use in both closed and open systems.

Technical parameters

Installation and connection

The IVN51.28 press stopper is installed using a standard press tool compatible with 28mm press fittings. The connection size is 28mm, and the fitting must be fully compressed to the specified dimension of 54mm to ensure a leak-tight seal. During installation, the installer should verify that the pipe is clean and free of burrs before pressing. A common mistake is failing to compress the fitting to the correct depth, which can lead to leaks or premature failure. The seal indicator must be fully engaged to confirm proper installation.

Compatibility and accessories

This stopper is compatible with standard IVAR press systems using 28mm stainless steel pipe. It is intended for use with press tools that meet the manufacturer’s specifications. No additional accessories are required for installation, but the press tool must be correctly calibrated and maintained. No related products are available for this model.

Technical background for designers

The IVN51.28 operates by forming a mechanical and hydraulic seal between the pipe and the fitting during the pressing process. The material, stainless steel Wst. Nr. The integration into the system depends on the system pressure and temperature, as well as the quality of the pressing process. Proper installation ensures long-term performance and minimises the risk of leaks or failures.

Service and operation

Once installed, the IVN51.28 requires no regular maintenance. However, during system inspections, it is recommended to visually check for signs of corrosion, mechanical damage, or leaks. If a leak is detected, the fitting must be replaced, as re-pressing is not recommended. The service life is primarily influenced by the quality of the installation and the operating conditions of the system.

Frequently asked questions

Can the IVN51.28 be used in solar heating systems?
Yes, the fitting is suitable for solar heating systems as it can withstand temperatures up to +120°C and is compatible with the media typically used in such systems.

Is the IVN51.28 compatible with inert gases?
Yes, the stainless steel material is suitable for use with inert gases, making it a reliable choice for industrial gas systems.
