RTJ gaskets are designed to seal by “initial line contact” or wedging action between the mating flange and the gasket. Usually used in oil, petroleum and chemical process fields. Precision machined, metallic sealing rings suitable for high pressure and high temperature applications. Type R (oval/ octagonal) R Style is available in both oval and octagonal…
One of the widely used seals, the spiral wound gasket depends on the mechanical characteristics of a formed metal strip which works as a spring, offering a better resilience under fluctuated pressure & temperature.
