Introduction

Application

Ring joint gasket are used in connection with RTJ flange, generates a strong seal between two mating flanges. When the flanges are fixed by bolts, ring joint gasket is squeezed into the groove of the flange, forming a tight seal between the mating flanges. In order to avoid destruction of the flanges, the material of the ring joint gaskets must be softer than the material of the flanges.
