DN200 Pipe Sealing Element

A sealing element sized to DN200 (200 mm nominal diameter, approximately 8 inches) provides a reliable leak-tight connection between pipes, fittings, flanges, valves, or drainage components in pipework systems. The exact seal type — gasket, O-ring, lip seal, or coupling seal — will depend on the application and mating components.

Material selection is critical to performance. Common options include EPDM for water and drainage systems, NBR for oil and fuel resistance, silicone for food-grade and high-temperature use, PTFE for aggressive chemical environments, and graphite for high-pressure or high-temperature applications. The right material ensures long service life and compatibility with the media being conveyed.

Applications:

• Water and wastewater systems
• Building drainage
• HVAC pipework
• Industrial process piping
• Chemical processing plants
• Food and beverage manufacturing
• Pharmaceutical production
• Marine and offshore pipework
