Universal rubber gasket - for flange joints - DN 125; 182x133x2mm IVAR.FASIT 202 PN 6

Product detailed description

This flanged joint gasket is commonly used in industrial and commercial installations where reliable sealing is required under moderate pressure and elevated temperatures. It is frequently found in heating systems, water distribution networks, and food processing equipment where hygiene and chemical resistance are essential. The gasket is installed between two flange faces to prevent leakage and ensure system integrity. It is suitable for applications where the operating conditions do not exceed the specified pressure and temperature limits.

During installation, the gasket is placed between the flange faces and compressed using bolts. The sealing effect is achieved through the elastic deformation of the rubber material under clamping force. The gasket must be compatible with the flange dimensions and bolt pattern to ensure even compression and prevent distortion. It is important to avoid over-tightening, which can lead to material failure or uneven sealing.

Technical parameters

The nominal diameter (DN 125) indicates the size of the flange connection and is used for selecting the correct gasket dimensions. The pressure rating (PN 6) defines the maximum allowable operating pressure and is essential for ensuring compatibility with the system’s design specifications. These parameters are critical for correct sizing and for ensuring that the gasket can withstand the expected operating conditions without failure.

Installation and connection

Installation requires placing the gasket between two mating flange faces. The flange connection should be clean and free of debris to ensure proper contact. The gasket thickness (2 mm) must be considered when determining the required bolt torque to avoid over-compression. The outer diameter (182 mm) and inner diameter (133 mm) must align with the flange dimensions.

Compatibility and accessories

This gasket is suitable for use with flanged fittings and valves rated for PN 6. It is compatible with systems operating with water, heating fluids and food-grade media. No additional accessories are required for standard installation. Ensure that the flange faces are parallel and free of irregularities to maintain a consistent seal. Related products include flanged valves and pipe fittings with matching flange dimensions.

Technical background for designers

The gasket is made of a composite material combining rubber and fibres to provide flexibility and strength. This material is resistant to water and common industrial fluids and is suitable for temperatures up to +180°C. The gasket’s performance depends on the uniformity of the clamping force and the condition of the flange surfaces. The PN 6 rating ensures that the gasket can handle moderate pressure without deformation. The sealing effect is maintained through the material’s ability to conform to minor surface imperfections and retain its shape under load.

Service and operation

During operation, the gasket should be inspected for signs of wear, such as cracking or hardening, which can indicate degradation. The integrity of the flange connection should be checked periodically to ensure that there are no leaks. No specific service intervals are provided in the technical data. If the gasket shows signs of failure, it should be replaced to prevent system downtime and potential safety hazards.
