Seal for flange joints PN 6

This category includes standardised rubber gaskets for flange joints operating under PN 6 pressure ratings. Designed for use in heating systems, water supply, and food industry applications, these gaskets are made from non-asbestos fibreglass-reinforced rubber. They operate at maximum temperatures of +180°C and have a consistent thickness of 2 mm across all sizes. The gaskets are suitable for sealing flanged connections in systems requiring reliable, durable and chemically stable sealing solutions.

The gaskets are available in a range of DN sizes from DN 20 to DN 200, with corresponding outer and inner dimensions to match standard flange dimensions. They are compatible with flange joints where tightening forces are specified according to DIN 28090 standards. These gaskets are ideal for use in systems where medium compatibility with water, heating fluids, or food-grade substances is required.

How to choose

• Match the gasket’s DN size to the flange nominal diameter (e.g., DN 50 corresponds to 96x60x2 mm dimensions).
• Ensure the gasket thickness (2 mm) is suitable for the flange gap and tightening force requirements.
• Verify compatibility with the system medium (e.g., water, heating fluids) and operating temperature (up to +180°C).
• Check that the gasket material (non-asbestos fibreglass-reinforced rubber) is suitable for the application environment.

Frequently asked questions

Can these gaskets be used in food industry applications?
Yes, the non-asbestos fibreglass-reinforced rubber is suitable for use in food industry systems where chemical resistance and hygiene are required.

What tightening standard applies to these gaskets?
Tightening forces must be applied according to DIN 28090 specifications to ensure proper sealing and prevent damage.
