O-ring - 54mm; FPM (red) IVAR.IVO.FPM C

Product detailed description

Press-fit pipe systems are widely used in residential and commercial buildings for central heating, cooling, fire protection and ventilation systems. These systems require reliable sealing solutions that maintain integrity under varying pressures and temperatures. Installers and technicians working with these systems must ensure accurate fitting and correct sealing to prevent leaks and maintain system efficiency. The IVAR O-ring model I007249 is specifically designed for such applications, providing a durable and adaptable sealing solution in closed and pressurised environments.

Sealing rings play a critical role in press-fit systems, ensuring tight connections between pipes and fittings without the need for welding or threading. The correct selection and installation of O-rings are essential to the long-term performance of the system. This O-ring is suitable for use in systems with carbon steel pipes and EPDM seals, making it compatible with a range of standard press-fit components. It is particularly suited to applications where the system is exposed to fluctuating temperatures and moderate pressure levels.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I007249
Brand	IVAR

The operating temperature range includes a minimum of -20°C, which is important when considering installation in colder environments or during seasonal variations. The nominal pressure rating of PN 16 indicates that the O-ring can support internal pressures up to 16 bar at standard operating temperatures. These parameters are essential for correctly sizing the seal and ensuring it meets the requirements of the specific application. The maximum operating temperature is limited to +120°C, beyond which performance may degrade.

Installation and connection

To install the O-ring, ensure the pipe end and fitting are clean and free from debris. Insert the O-ring into the groove on the fitting before pressing the pipe into place using a certified pressing tool. Verify that the tool is calibrated for the specific pipe and fitting size. A common mistake is incorrect insertion depth, which can lead to misalignment and potential leaks. After pressing, inspect the joint visually and use a go/no-go gauge to confirm proper engagement. Avoid reusing the O-ring if the pressing process fails or is interrupted.

Compatibility and accessories

This O-ring is compatible with IVAR press-fit systems that use carbon steel pipes and EPDM sealing rings. It is intended for use with fittings of the same nominal pressure rating. When replacing or installing new components, ensure that all parts are from the same system to maintain compatibility. Additional accessories such as pressing tools, measuring instruments and cleaning supplies are typically required for installation but are not included with the O-ring.

Technical background for designers

The O-ring functions by compressing between the pipe and fitting during the pressing process, creating a mechanical and hydraulic seal. The FPM (fluorocarbon rubber) material offers resistance to oils, fuels and certain chemicals, making it suitable for a variety of industrial and mechanical applications. The sealing effectiveness depends on the correct pressing depth and alignment. Long-term performance is influenced by exposure to extreme temperatures and chemical environments beyond the specified limits.

Service and operation

No regular maintenance is required for this O-ring once installed correctly. However, periodic visual inspections are recommended to detect signs of wear or degradation, especially in systems with frequent thermal cycling. If the system shows signs of leakage or reduced performance, the affected joints should be inspected and replaced if necessary. The O-ring is not suitable for potable water applications and should not be used in such systems.

Frequently asked questions

Can this O-ring be used in a solar water heating system?
Yes, provided the system operates within the specified temperature range of -20°C to +120°C and the pressure does not exceed PN 16.

Is this O-ring compatible with IVAR press-fit fittings of other sizes?
It is specifically designed for 54mm press-fit connections. Using it with other sizes will result in improper sealing and potential failure.

Can this O-ring be used in a pressurised fire protection system?
Yes, as long as the system pressure does not exceed PN 16 and the operating temperature remains within the specified range.
