Flat Ring Gasket | Raised Face Gasket Technical Specifications & Engineering Performance
Advanced Technical Design of Flat Ring Gasket / Raised Face Gasket
RUBBER-KU Flat Ring Gaskets and Raised Face Gaskets are engineered to provide reliable sealing performance under a wide range of pressure, temperature, vacuum, vibration, and chemical exposure conditions. Manufactured from premium industrial-grade elastomers and PTFE materials, these gaskets are designed to meet the stringent requirements of industrial piping systems, process equipment, pumps, valves, pressure vessels, heat exchangers, storage tanks, and flange assemblies.
Our gasket designs are based on proven sealing engineering principles that maximize gasket stress, improve sealing efficiency, and reduce the risk of leakage in critical applications.
Technical Function of a Raised Face Gasket
A Raised Face Gasket is specifically designed to fit within the raised sealing area of a Raised Face (RF) flange.
When flange bolts are tightened:
- Bolt load is transferred directly to the gasket.
- The gasket compresses uniformly.
- The material flows into flange surface irregularities.
- Leakage paths are sealed.
- Internal pressure is contained.
Unlike Full Face Gaskets, Raised Face Gaskets concentrate the available bolt load onto a smaller sealing area, producing higher gasket seating stress and improved sealing performance.
Engineering Advantages
✔ Higher gasket compression force
✔ Increased sealing stress
✔ Better flange load efficiency
✔ Improved blowout resistance
✔ Enhanced pressure retention
✔ Reduced leakage risk
✔ Superior long-term sealing stability
