O-ring - 54mm; FPM (green) IVAR.IVO.FPM Z

Product detailed description

This O-ring is used in press and coupling systems for heating, industrial and fire protection applications. It ensures tight seals in closed pressurised systems, including heating circuits, cooling lines, fire suppression systems, and climate control piping. Installers working with steel pipe systems benefit from the ease of installation without the need for welding or threading. The O-ring is compatible with IVAR press fittings and supports a wide range of pipe diameters, making it suitable for both new installations and system upgrades.

The seal is made from FPM (fluorocarbon rubber) and is designed to maintain integrity under varying pressure and temperature conditions. It is used with carbon steel press fittings and provides reliable sealing in non-potable water and industrial gas applications. The O-ring is part of a system that allows rapid assembly and disassembly, reducing installation time and ensuring long-term performance.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I002855
Brand	IVAR

The operating temperature range includes a minimum of -20°C, making it suitable for cold environments such as unheated warehouses or outdoor systems. The nominal pressure rating of PN 16 indicates its ability to handle medium-pressure systems. These parameters are essential for selecting the correct seal size and material for the intended application, ensuring compatibility with the system’s hydraulic and thermal conditions.

Installation and connection

To install the O-ring, ensure the pipe end is clean and free of burrs before inserting it into the coupling. The O-ring should be seated correctly in the groove of the fitting to avoid misalignment during pressing. Use a calibrated press tool according to the manufacturer’s guidelines to form the secure connection. Verify that the tool is set to the correct pipe size and that the coupling is fully seated against the stop. Common mistakes include using incorrect tooling or failing to inspect the O-ring for damage before installation, which can lead to leaks or reduced system efficiency.

Compatibility and accessories

This O-ring is compatible with IVAR press couplings and fittings designed for steel pipe systems. It works with IVAR.IVO.FPM Z series components and is suitable for use with standard press tools. When installing, ensure that all fittings and tools are from the same system to maintain compatibility. Additional components such as press couplings, expansion joints and support brackets may be required depending on the system layout and application.

Technical background for designers

FPM (fluorocarbon rubber) is selected for its resistance to heat and chemical exposure, making it ideal for industrial and heating applications. The O-ring forms a static seal between the pipe and fitting, relying on the compressive force generated during pressing to maintain integrity. The system is designed for closed-loop applications where pressure and temperature fluctuations occur. The material’s properties contribute to long-term durability, provided the system operates within the specified limits and the installation is carried out correctly.

Service and operation

No regular maintenance is required for the O-ring once installed correctly. However, periodic inspections should be conducted to check for signs of wear, cracking or leakage. If the system is exposed to extreme conditions beyond the specified parameters, it may be necessary to replace the seal. Always refer to the manufacturer’s technical documentation for guidance on service intervals and replacement criteria.

Frequently asked questions

Can the O-ring be used in heating systems with expansion joints?
Yes, provided the system operates within the specified temperature and pressure ranges and the expansion joint is compatible with the press system.

Is the O-ring suitable for use with inert gases?
Yes, the FPM material is compatible with inert gases as long as the operating conditions remain within the specified parameters.

Can the O-ring be reused after disassembly?
No, the O-ring is a single-use component and should be replaced after any disconnection to maintain system integrity.

How is the O-ring positioned during installation?
The O-ring is placed in the groove of the coupling before the pipe is inserted and pressed into place. Ensure it is seated evenly to avoid misalignment.
