Various embodiments of the present invention provide improved face seal gaskets for use in connecting meters and other devices to pipelines. The improved face seal gaskets include a planar annular ring portion and one or more tabs extending substantially perpendicularly from the annular ring portion. In use, the annular ring portion is disposed adjacent a sealing surface on the inlet or outlet of the device to facilitate a fluid tight connection between the device and the pipeline. The tabs engage complementary grooves formed in the inlet or outlet portions of the device to facilitate alignment of the annular ring to the sealing surface thereon. The tabs may also retain the face seal gasket adjacent the sealing surface to facilitate improved installation of the device to the pipeline. |
