- Octagonal: For new flanges that do not require more than the minimum sealing point.
- Oval: When the flanges have suffered wear and ensure tightness need more points.
- RX: gaskets designed for pressures up to 700 bar, self-sealing using a pressure effect without tension, factor that improves the efficiency of gasket as the pressure increases.
- BX: BX-specific RTJ flanges for pressures up to 1500 bar. The BX ring has a horizontal hole which acts as pressure equalizer.
Coestan has an emergency department up to 24 hours or scheduled deliveries at very competitive prices. The usual delivery time is 1 week. RTJ gaskets are manufactured according to API 6A and ASME B16.20-standards and are classified with a number, depending on the size and pressure must endure.
