Abstract:
1. A joint comprising first and second members defining a fluid passageway and a gasket disposed within the fluid passageway and installed in sealing arrangement between the first and second members, the joint further comprising each of a joint counterbore portion and a joint groove portion, a counterbore corner extending from the joint counterbore portion and a groove portion corner extending from the joint groove portion; wherein the gasket is a malleable gasket suitable for high purity fluid delivery systems, the gasket comprising a first side, an opposed second side, an outside diameter, and an inside diameter, the first side comprising a first circular sector extending inwardly from the outside diameter to a flat first sealing region, the flat first sealing region extending inwardly to a raised inner lip, the second side comprising a raised outer lip extending inwardly from the outside diameter to a flat second sealing region, the flat second sealing region extending inwardly to the inside diameter such that there are no protrusions disposed on the second side between the flat second sealing region and the inside diameter, wherein the raised inner lip and the raised outer lip are circumferentially spaced from one another, and further wherein the raised inner and outer lips are adapted to align the gasket by engaging features in a face of one or more fluid delivery elements being joined; and further wherein the inner raised lip aligns the gasket with the joint counterbore portion and the outer raised lip aligns the gasket with the joint groove portion, such that when the joint is completely assembled, the counterbore corner shears into the gasket first sealing region and the groove portion corner shears into the gasket second sealing region.
