Sealing washer set - 12mm; 1/2"; 18,5x11x2mm IVAR.OMNIA SO

Product detailed description

High-temperature sealing washer sets are essential components in systems where elevated temperatures and pressures are present. They are commonly used in residential and commercial heating installations, industrial piping and solar thermal systems. In these environments, threaded connections require reliable sealing solutions that can withstand repeated thermal cycling and mechanical stress. This product is designed for use with water-based fluids and is particularly suited to applications involving steam, hot water or thermal oil. Installers working on boiler circuits, heat exchangers or food processing systems will benefit from the robust sealing properties of this washer set.

The installation process typically involves preparing the mating surfaces, applying a thin layer of sealing compound if required, and tightening the connection according to the specified torque values. Ensuring correct alignment and uniform compression of the washer is critical to avoid leaks or premature failure. The washer should not be reused once removed, as its structural integrity may be compromised.

Technical parameters

The nominal pressure rating of PN 16 indicates that the gasket is suitable for systems operating up to 16 bar. The maximum operating temperature of +370°C makes it compatible with high-temperature applications such as steam lines or industrial heat transfer systems. These parameters are essential for determining the suitability of the gasket in relation to the system’s operating conditions and for ensuring long-term performance.

Installation and connection

For proper installation, the connection size must match the 1/2 inch thread of the fitting. The washer dimensions are 18.5x11x2 mm, which allows it to fit standard threaded joints in heating and industrial piping. Before installation, check that the mating surfaces are clean and free from burrs or debris. Apply even pressure during tightening to ensure uniform compression of the washer. A common mistake is over-tightening, which can deform the washer and reduce its effectiveness. Always follow the manufacturer’s recommended torque settings when applicable.

Compatibility and accessories

This sealing washer is compatible with threaded fittings and valves that accept 1/2 inch connections. It is suitable for use with metal-to-metal or flanged joints in heating and industrial systems. When installing, ensure that the mating components are made from compatible materials to prevent galvanic corrosion. Additional components such as sealing compounds or thread sealants may be required depending on the specific application and system requirements.

Technical background for designers

The washer is constructed from fibre-reinforced rubber, a material known for its resistance to high temperatures and chemical stability. This material ensures that the gasket maintains its integrity under thermal stress and mechanical loading. The design allows for a tight seal between threaded components while accommodating slight misalignments. The service life of the gasket is influenced by factors such as operating temperature, frequency of disassembly and exposure to aggressive media. Proper sizing and selection based on system parameters are essential for optimal performance.

Service and operation

During operation, regular visual inspections should be carried out to check for signs of wear, deformation or leakage. If the washer shows any damage or has been removed for maintenance, it should be replaced with a new unit. There are no defined service intervals provided in the technical documentation, so replacement should be based on observed condition rather than a fixed schedule. Avoid exposing the gasket to temperatures beyond its rated limit, as this can cause irreversible degradation.

Frequently asked questions

Can this sealing washer be used in food processing systems?
Yes, it is approved for use in the food industry and is suitable for applications involving water and non-aggressive fluids.

Is it compatible with steam systems?
Yes, the maximum operating temperature of +370°C makes it suitable for steam lines and high-temperature industrial processes.

Can the washer be reused after removal?
No, once the washer has been removed, its structural integrity may be compromised and it should not be reused.

What is the recommended tightening procedure?
Tighten the connection gradually and evenly to ensure uniform compression of the washer. Follow the torque specifications outlined in DIN 28090 for best results.
