Sealing rings are essential components in press-fit pipe systems, ensuring leak-free connections in heating, irrigation, and industrial applications. Installers working in central heating systems, fire suppression, and compressed air systems frequently use O-rings to create secure, maintenance-free joints. These systems often require sealing components that can withstand fluctuating temperatures and pressures, making materials like FPM (fluoroelastomer) suitable for long-term performance.

In industrial and commercial buildings, press-fit systems are commonly used for their ease of installation and reliability. The IVAR 15mm FPM O-ring is designed for use in such environments, where it supports the integrity of connections in closed-loop systems and high-pressure applications. It is particularly suited for use in systems operating in cold climates or with intermittent high-temperature exposure.

Technical parameters

Operating temperature	-20 °C
Nominal pressure	PN 16
Code	I002849
Brand	IVAR

The operating temperature range of -20°C to +85°C, with a maximum of +120°C, allows for use in a wide range of environments, including cold storage facilities and industrial heating systems. The nominal pressure rating of PN16 ensures the O-ring can handle systems operating at up to 16 bar, which is typical for central heating and fire suppression systems. These parameters are critical for selecting the correct sealing ring for the intended application and system conditions.

Installation and connection

During installation, the O-ring is inserted into the groove of the fitting or pipe before the components are joined using a press tool. The connection size must match the internal diameter of the pipe and the fitting. Installers should ensure that the O-ring is not damaged during insertion and that the groove is free of debris. Common installation errors include using the wrong size O-ring or failing to check the groove for damage, which can lead to leaks or premature failure.

Compatibility and accessories

This O-ring is compatible with IVAR steel pipe systems and fittings designed for press-fit connections. It is intended for use with carbon steel fittings and EPDM O-rings in other parts of the system. No additional accessories are required for standard installation, but installers should ensure that all components are from the same system to maintain compatibility and system integrity.

Technical background for designers

The O-ring functions by creating a tight seal between the pipe and fitting when compressed during the pressing process. The material's flexibility and resilience allow it to maintain the seal under varying pressure and temperature conditions. The system's performance is influenced by the quality of the press connection and the condition of the groove in the fitting.

Service and operation

Once installed, the O-ring requires no maintenance under normal operating conditions. However, regular inspections should be carried out to check for signs of wear, deformation, or leakage. If any issues are detected, the affected connection should be disassembled and the O-ring replaced. No specific service intervals are provided, but it is recommended to inspect the system during routine maintenance checks.

Frequently asked questions

Can the IVAR 15mm FPM O-ring be used in fire suppression systems?
Yes, it is suitable for use in fire suppression systems operating within the specified temperature and pressure ranges. It supports the integrity of press-fit connections in such applications.

Is the O-ring compatible with other IVAR system components?
Yes, it is designed to work with IVAR steel pipe systems and press-fit fittings. It is not compatible with other sealing systems or materials outside the IVAR range.

Can the O-ring be reused after disassembly?
No, the O-ring is a single-use component and should be replaced after each disassembly to ensure a reliable seal.

What is the maximum operating temperature for this O-ring?
The maximum operating temperature is +120°C, with a standard range of -20°C to +85°C. Exceeding this limit may reduce the O-ring's performance and lifespan.
