In professional heating and plumbing installations, press-fit connections require precise sealing components to ensure system integrity. This O-ring is commonly used in systems such as heating circuits, fire suppression systems, compressed air lines and solar thermal installations. It is particularly suited for applications involving fluctuating temperatures and media such as water, steam or inert gases. The sealing element must withstand mechanical stress during installation and maintain performance under operational conditions.

The O-ring is typically installed in press-fit fittings made of stainless steel, where it forms a tight seal between the pipe and fitting. It is essential to ensure that the fitting is fully pressed onto the pipe, and the press-fit indicator is engaged to confirm correct installation. The O-ring must remain undamaged during handling and installation to prevent leaks or premature failure.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I002984
Brand	IVAR

The operating temperature range of -20°C to +85°C allows the O-ring to perform in both cold and moderately heated environments. The maximum temperature of +120°C should be considered for short-term exposure only. The nominal pressure rating of PN16 indicates the maximum allowable internal pressure for which the O-ring is suitable. These parameters are critical for selecting the correct sealing solution based on system design and environmental conditions.

Installation and connection

To install the O-ring correctly, first inspect the press-fit fitting and the pipe end for damage or debris. The O-ring must be seated in the groove of the fitting before pressing the fitting onto the pipe. Ensure that the press-fit tool is compatible with the fitting size and that the press depth is within the manufacturer’s specifications. After pressing, verify that the press-fit indicator is engaged up to 54 mm. A common mistake is failing to clean the pipe end properly, which can lead to poor sealing or damage to the O-ring during installation.

Compatibility and accessories

This O-ring is specifically designed for use with press-fit fittings of type IVAR.IVO.FPM Z. It is intended for use with pipes that have been prepared for press-fit connections. When ordering, ensure that the corresponding press-fit fittings and tools are available. Additional components such as pipe cutters, deburring tools and press-fit indicators may be required for a complete installation process.

Technical background for designers

The O-ring is made from FPM (fluorocarbon ) material, known for its resistance to heat and chemical exposure. It is designed to maintain its and sealing properties under the specified temperature and pressure ranges. The O-ring is integrated into the press-fit system to create a leak-tight connection between the pipe and the fitting. The choice of FPM ensures compatibility with a range of media, including water, steam and inert gases. Long-term performance is influenced by factors such as correct installation, media compatibility and operating conditions.

Service and operation

During operation, the O-ring requires no active maintenance. However, periodic visual inspections should be carried out to detect signs of wear, deformation or chemical degradation. If the system is exposed to media outside the specified compatibility range, the O-ring may degrade prematurely. There are no defined service intervals for this component, as it is designed for long-term use under normal operating conditions. In the event of a suspected leak, the system should be depressurised and the connection inspected for damage or improper installation.
