O-ring - 35mm; FPM (green) IVAR.IVO.FPM Z

Product detailed description

This O-ring is commonly used in press-fit pipe systems within industrial and heating installations. It ensures reliable sealing in closed systems such as central heating, fire protection, compressed air lines, and cooling circuits. Installers working with carbon steel pipes and EPDM gaskets integrate these seals during mechanical compression fitting assembly. The O-ring is suitable for environments exposed to mechanical stress and fluctuating pressures, particularly where non-metallic sealing solutions are required.

The fluorocarbon rubber (FPM) material provides chemical resistance and dimensional stability under pressure. It is especially useful in applications involving inert gases, industrial processes, and non-potable water systems. The seal supports quick installation without welding or threading, making it ideal for complex pipe networks with multiple branch points.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I002853
Brand	IVAR

The operating temperature of -20 °C indicates the lowest ambient or medium temperature for which the O-ring is rated. This is critical when selecting seals for cold environments such as external piping or unheated storage areas. The nominal pressure rating of PN 16 defines the maximum continuous operating pressure the seal can handle, influencing system design and component compatibility.

Installation and connection

During installation, the O-ring is placed into the designated groove of the fitting or socket. Ensure that the groove is free from burrs and contaminants before insertion. The press-fit assembly requires careful alignment to avoid twisting or misalignment of the seal. Check that the mating surfaces are clean and undamaged. Common installation errors include over-compression, improper seating, and incorrect orientation, all of which can lead to premature failure or leakage. Use appropriate tools for pressing and verify that the final assembly is tight and secure.

Compatibility and accessories

This O-ring is compatible with press-fit connections using carbon steel pipes and IVAR fittings. It pairs well with IVAR.IVO systems and is designed for use with press-fit couplings such as IVAR.IVC12. Additional components such as couplings, reducers, and press tools should be sourced separately depending on the specific installation requirements. Refer to the manufacturer’s documentation for full compatibility details.

Technical background for designers

FPM (fluorocarbon rubber) is selected for its resilience to heat, oils, and solvents. It retains flexibility across a wide temperature range and resists deformation under pressure. The O-ring functions by creating a static seal between mating parts through radial compression. Its performance depends on correct groove geometry, surface finish, and fluid compatibility. The material does not support drinking water certification, so it is not recommended for potable water systems.

Service and operation

Routine inspection is necessary for signs of wear, cracking, or hardening due to prolonged exposure to high temperatures or aggressive media. Replace the O-ring if any physical damage is observed. There are no scheduled service intervals provided in the technical data; however, regular visual checks are advised in high-stress or high-risk environments.
