Sealing member and retainer assembly for sealing non-grooved joints

摘要

A self-locating sealing assembly in which a compressible sealing member and an encircling retainer ring make an assembly for sealing non-grooved joints. The sealing assembly has special application to a standard type pipe flange having a relatively projected sealing surface. The sealing assembly has clip type locating means which make a peripheral engagement with the projected sealing surface concentrically to locate the sealing assembly and to hold it located while the joint is being closed.
