Reducer - with one plug-in end - N - 88,9-76,1mm IVAR.IVN12

Product detailed description

Stainless steel reducers are essential components in press-fitting systems where dimensional transitions are required. This model is commonly used in residential and commercial buildings for heating, sanitary, and industrial installations. It ensures a secure and leak-free connection between different pipe diameters in systems operating under moderate pressure and temperature conditions. Installers working on HVAC systems, solar installations, or fire suppression systems will find this reducer suitable for connecting press-fitted and diameter-based piping components.

The reducer is particularly useful in applications where a single press connection is required on one end and a diameter-based connection on the other. It is frequently used in systems where space constraints or design requirements necessitate a transition between different pipe sizes. The EPDM O-ring ensures a tight seal, and the stainless steel construction provides resistance to corrosion and mechanical stress, making it suitable for long-term use in a variety of environments.

Technical parameters

Material	Stainless steel grade Wst. Nr. 1.4404 (AISI 316L), EPDM O-ring
Operating temperature	-20 °C
Nominal pressure	PN 16
Code	IVN12.8976
Brand	IVAR

The nominal pressure rating of PN 16 indicates the maximum pressure the fitting can withstand at reference temperature conditions. The operating temperature range from -20°C to +85°C, with a maximum of +120°C, defines the thermal limits for safe operation. These parameters are critical for selecting the correct fitting for the intended system, ensuring compatibility with the operating conditions and media type.Installation and connection This reducer features one press connection and one diameter-based connection. The press end requires a press tool to secure the fitting to the pipe, while the other end is inserted into a corresponding diameter pipe. The installer must ensure the press connection is fully compressed and the indicator mark is visible to confirm a secure fit. The diameter end should be inserted to the correct depth and aligned with the mating component. Common installation errors include insufficient press force, misalignment, or failure to check the indicator mark. Always verify the fit before proceeding with system testing.Compatibility and accessories This reducer is compatible with standard press-fitting systems using 1.4404 stainless steel piping and EPDM-sealed components. It is intended for use with press tools designed for this type of fitting. No additional accessories are required for basic installation, but a press tool and suitable measuring instruments are essential for proper fitting. Related products include press-fitting pipes, press tools, and EPDM O-rings for replacement or maintenance purposes.Technical background for designers The reducer operates by creating a mechanical and hydraulic seal between two pipe sections of different diameters. The stainless steel body provides structural integrity and resistance to corrosion, while the EPDM O-ring ensures a tight seal against leakage. The press connection relies on a deformation process that locks the fitting to the pipe, creating a permanent and leak-free joint. The material properties of 1.4404 stainless steel ensure compatibility with a wide range of fluids and gases, including those found in heating, solar, and industrial systems. The design allows for integration into systems where dimensional transitions are necessary without compromising flow efficiency or system integrity.Service and operation Routine inspection is recommended to ensure the reducer remains leak-free and properly connected. Check the press connection for any signs of deformation or wear, and verify that the indicator mark is still visible. If the connection becomes loose or shows signs of leakage, it should be replaced immediately. No regular maintenance is required beyond visual inspection and system testing. The EPDM O-ring should be replaced if damaged or degraded to maintain sealing performance.Frequently asked questions

Can this reducer be used in solar heating systems?
Yes, the reducer is suitable for solar heating systems due to its temperature range and material compatibility with the media used in such systems.

Is the EPDM O-ring replaceable?
Yes, the EPDM O-ring can be replaced if damaged or degraded to maintain the sealing integrity of the connection.

Can the reducer be used in fire suppression systems?
Yes, the reducer is suitable for fire suppression systems as it meets the pressure and temperature requirements for such applications.

What is the maximum operating temperature of the reducer?
The maximum operating temperature is +120°C, beyond which the fitting may not perform as intended.
