Reducer - with one plug-in end - N - 76,1-54mm IVAR.IVN12

Product detailed description

Stainless steel reducers with one plug-in end are commonly used in commercial and industrial buildings to adapt pipe diameters in press-fitting systems. Installers frequently encounter these fittings when connecting boiler circuits, hot water loops, and fire suppression systems. In such applications, precise alignment and secure compression are essential to prevent leaks and ensure long-term reliability.

In heating and plumbing systems, this type of fitting helps integrate components of different sizes while maintaining hydraulic continuity. It is often found in solar thermal systems, air pressure circuits, and inert gas lines. Proper installation involves careful preparation of the pipe ends and verification of the compression tool settings to achieve consistent results across multiple joints.

Technical parameters

Installation and connection

The reducer is installed using a press tool that compresses the plug-in end onto the pipe. The first step is to clean and measure the pipe ends to confirm correct dimensions. The pipe should then be inserted into the fitting until it reaches the stop mark. After pressing, the installer must verify the depth indicator to confirm proper engagement. Common errors include incorrect pipe insertion depth or using the wrong press tool, which can lead to incomplete compression and potential leakage.

Compatibility and accessories

This reducer is compatible with standard stainless steel press-fitting systems designed for heating, sanitary, and industrial applications. It requires matching press tools and stainless steel pipes with appropriate diameters. No additional parts are required for basic installation, though testing equipment may be necessary after installation to confirm system integrity.

Technical background for designers

The fitting operates by forming a mechanical seal through radial compression of the plug-in end around the pipe. The 1.4404 stainless steel body offers high corrosion resistance and durability in aggressive environments. The EPDM sealing ring enhances the tightness of the joint. For optimal performance, the system design must account for thermal expansion and contraction of the piping network. The material combination ensures compatibility with non-corrosive fluids and gases typically encountered in the listed applications.

Service and operation

During regular inspections, the depth indicator should be checked to confirm the fitting has not shifted or become loose due to vibration or thermal cycling. No scheduled maintenance is required beyond visual checks. Any signs of leakage or misalignment indicate the need for re-pressing or replacement of the affected component.

Frequently asked questions

Can this reducer be used in fire sprinkler systems?
Yes, the material and pressure ratings make it suitable for fire suppression applications according to the provided usage description.

Is the EPDM sealing ring compatible with all types of fluids?
The EPDM sealing ring is suitable for most non-aggressive fluids and gases, but specific chemical compatibility should be verified according to the application media.

How deep should the pipe be inserted into the fitting during installation?
The pipe should be inserted until it reaches the internal stop mark inside the fitting. This ensures the correct engagement and prevents under- or over-compression.

What happens if the depth indicator shows incomplete compression?
If the depth indicator does not reach the correct position, the fitting is not fully compressed. This compromises the joint’s integrity and requires re-pressing or replacement.
