What are rubber-steel gaskets and why are they so popular?
Rubber-steel gaskets combine the best of two materials: the flexibility and sealing performance of rubber with the strength and stability of steel. It’s a smart design where a steel ring is coated with a layer of rubber (such as NBR, EPDM, or FKM). This creates a reliable, long-lasting seal that performs well in a wide range of applications.
The steel core helps the gasket maintain its shape, even under pressure or when bolts are tightened. The rubber layer adapts to surface imperfections in the flange, ensuring a tight, leak-proof connection without needing excessive torque. That makes installation easier and safer. Where Are They Used?
Rubber-steel gaskets are commonly used in water systems, HVAC, installation technology, chemical processing, and the food industry. Typical applications include flange connections in piping systems for water, air, oil, or chemicals. They're suitable for both low and moderate pressures, and depending on the rubber type, can handle various temperatures and aggressive media. Why Choose Rubber-Steel?
• Reliable sealing with relatively low bolt load
• Low maintenance thanks to rubber’s resilience
• Versatile—available in different rubber types
• Easy to install without damaging the gasket
• Good chemical resistance (depending on rubber)
