General Questions & Answers

What is the difference between type R and RX gaskets?

Style RX is a pressurized modification of the standard Style R gasket. The RX is designed for the same groove design as a standard Style R, making the gaskets interchangeable.

The RX design uses a pressure-activated effect that improves the efficiency of the gasket as the internal pressure of the system increases. The outer chamfers of the gasket ring make initial contact and provide a seal against the outer surfaces of the flange groove. As the internal pressure increases, the load of the gasket against the groove also increases, improving the sealing properties of the gasket. RX-type gaskets are more resistant to shock loading, test pressure shocks and drilling vibrations.

Be careful when swapping these styles, as RX gaskets are longer and add length to the finished assembly.
