PRESS GAS reducer - with one plug-in end - 54-42mm IVAR.IVN12 GAS

Product detailed description

Gas distribution systems in industrial and commercial buildings require reliable fittings to maintain safe and efficient operation. This stainless steel reducer is used in press-fit systems where a transition between different pipe diameters is necessary. It is commonly installed in gas supply lines for heating systems, industrial processes, and gas storage facilities. The fitting ensures a secure connection without the need for welding, reducing installation time and potential for leaks. Installers must ensure correct alignment and compatibility with the press tooling to achieve a leak-tight seal.

The reducer is suitable for use in systems transporting natural gas, biogas, and liquid propane. It is designed to handle the specific demands of gas media, including potential fluctuations in pressure and temperature. The press connection requires a compatible tool to compress the fitting onto the pipe, ensuring a durable and maintenance-free joint. The threaded end allows for connection to other components such as valves, regulators, or meters.

Technical parameters

Material	Stainless steel Wst. Nr. 1.4404 (AISI 316L), sealing O-ring HNBR yellow
Operating temperature	-20 °C
Nominal pressure	PN 5
Code	IVNGAS12.5442
Brand	IVAR

The operating temperature range of -20 °C to +70 °C allows the fitting to be used in both cold and warm environments, such as outdoor installations or heated utility rooms. The nominal pressure rating of PN 5 indicates the fitting is suitable for low-pressure gas systems. These parameters are essential for selecting the correct fitting based on the system's operating conditions and the type of gas being transported.

Installation and connection

To install the reducer, the press connection must be prepared by inserting the pipe into the fitting and using a calibrated press tool to compress the fitting around the pipe. The threaded end is then connected to the corresponding component using a standard wrench. It is important to verify that the press tool is correctly set for the pipe diameter and that the O-ring is undamaged before installation. Common installation errors include using incorrect tooling, which can lead to an incomplete press, or failing to clean the pipe before insertion, which can compromise the seal.

Compatibility and accessories

This reducer is compatible with other IVAR press fittings and components designed for gas systems. It is intended for use with press tools that support the specified pipe diameters. Additional components such as valves, regulators, or pressure gauges may be required depending on the system configuration. Installers should ensure that all components are from the same manufacturer to maintain system integrity and compatibility.

Technical background for designers

The reducer functions by creating a mechanical seal between the pipe and the fitting through the press connection. The stainless steel construction (1.4404/AISI 316L) provides resistance to corrosion and ensures long-term durability in gas environments. The HNBR O-ring provides a flexible and reliable seal that maintains integrity over time. The design allows for integration into existing press-fit systems without the need for additional supports or reinforcement. The service life and efficiency of the fitting depend on correct installation, the quality of the press tooling, and the operating conditions of the gas system.

Service and operation

No specific service intervals are required for this fitting. Routine inspections should be carried out to check for signs of wear, damage, or leaks. The press connection should remain intact, and the O-ring should be inspected for signs of degradation. If any issues are detected, the fitting should be replaced immediately to prevent gas leaks. The threaded connection should also be checked for tightness and signs of corrosion.

Frequently asked questions

Can this reducer be used with biogas systems?
Yes, the fitting is approved for use with biogas and is suitable for low-pressure gas distribution systems.

Is a specific press tool required for installation?
Yes, the fitting must be installed using a calibrated press tool that is compatible with the specified pipe diameter and fitting type.

Can the O-ring be replaced after installation?
No, the O-ring is an integral part of the fitting and cannot be replaced once the fitting is installed and press-connected.

Is this fitting suitable for outdoor installations?
Yes, the stainless steel construction and O-ring material provide resistance to environmental factors, making it suitable for outdoor use within the specified temperature range.
