O-ring - 35mm; FPM (red) IVAR.IVO.FPM C

Product detailed description

Press-fit sealing rings are essential components in closed-system piping for heating, fire suppression, compressed air and inert gas applications. They ensure leak-free connections without the need for welding or threading. These systems are typically found in residential and commercial buildings, including central heating, chilled water, and solar thermal installations. Installers working with these systems require reliable sealing solutions that can withstand fluctuating pressures and temperatures.

The O-ring is used in conjunction with press fittings to create a secure mechanical and hydraulic seal between pipe ends. It is particularly suited for environments where rapid assembly and disassembly are necessary, such as during maintenance or system modifications. The sealing ring is made from FPM (fluorocarbon rubber), which offers resistance to a range of fluids and environmental conditions.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I007247
Brand	IVAR

The operating temperature range ensures the O-ring remains functional in both cold and moderately hot environments. The nominal pressure rating of PN 16 indicates its suitability for medium-pressure applications. These parameters are critical when selecting the correct component for a specific system and ensuring long-term performance under expected operating conditions.

Installation and connection

To install the O-ring, ensure the pipe ends are clean and free of debris. Insert the O-ring into the groove of the fitting, then assemble the pipe and fitting using a certified press tool. Check that the tool is correctly aligned and that the pressing operation is performed according to the manufacturer’s instructions. Common installation errors include misalignment, insufficient tool calibration, and using incorrect pressing force, all of which can compromise the seal.

Compatibility and accessories

This O-ring is compatible with IVAR press fittings of appropriate size and design. For full system functionality, ensure that all fittings and pipes are from the same press-fit system. Additional components such as press tools and inspection gauges may be required for proper installation and verification.

Technical background for designers

The O-ring relies on its elastic properties to conform to the mating surfaces of the pipe and fitting, creating a tight seal. FPM is chosen for its resistance to oils, fuels, and certain chemicals, making it suitable for industrial and heating applications. The material’s resilience to thermal cycling enhances system reliability. The press-fit connection integrates mechanically and hydraulically into the system, eliminating the need for additional support structures. Longevity is influenced by correct installation, maintenance of system pressure within limits, and avoidance of exposure to incompatible media.

Service and operation

Regular visual inspections should be carried out to check for signs of wear, deformation or leakage. If the system is subjected to temperatures beyond the specified range or excessive pressure, the integrity of the seal may degrade over time. No scheduled service intervals are specified, but any suspected faults should be investigated promptly to prevent further damage.

Frequently asked questions

Can this O-ring be used in a central heating system?
Yes, it is suitable for central heating installations, provided the system operates within the stated temperature and pressure limits.

Is the O-ring compatible with press tools other than IVAR?
It should only be used with press tools specifically calibrated for IVAR press-fit systems to ensure a correct and secure connection.

Can this O-ring be used in drinking water systems?
No, the product is not approved for use in drinking water applications.
