Durlon® RTJ Style RX

Durlon® RTJ gaskets are precision machined from solid metal and are designed for high pressure and high temperature services. They seal by creating very high unit load, metal-to-metal line contact with special mating flanges. Metals are typically chosen so that the ring gasket is softer than the flange material in order to prevent damage to the flanges and thereby causing plastic flow of the gasket into the flange faces. The design of the gasket or cross section is chosen based on the existing flange configuration and designed maximum system pressure. Gasket and flange surface finishes and dimensional accuracy along with gasket hardness must be carefully controlled in order to obtain and maintain an effective seal.

Style RX
The Durlon® Style RX gasket has a unique self-sealing action. The outside bevels of the ring make the initial contact, thus providing a seal against the grooves' outer surfaces. As the internal pressure increases, so does the gasket loading stress against the groove thus improving the gaskets sealing characteristics. Design features of the Style RX gasket make it more resistant to shock load, test pressure shock and drilling vibration. This style of RTJ is completely interchangeable with standard Style R groove designs. Care should be taken when interchanging these styles as RX gaskets are taller and will add length to the finished assembly.
