Abstract: A coupling assembly orientated about a longitudinal axis and having a first sleeve and second sleeve configured to be tightened to a fluid conduit, a radial-split gasket configured to be positioned between the sleeves and the fluid conduit and having an outer gasket layer and a separate inner gasket layer that are configured to be selectively disengaged from each other, and an inner circumferential surface of the outer gasket layer and/or an outer circumferential surface of the inner gasket layer comprising a plurality of circumferentially spaced retaining protrusions interfacing between the inner and outer gasket layers to maintain angular alignment of the inner and outer gasket layers about the longitudinal axis.

Abstract: A conduit coupling assembly having first and second sleeve members configured to be tightened to a fluid conduit, an arcuate radial split gasket configured to be positioned between the first and second sleeve members and the fluid conduit, the first sleeve member having an inwardly-facing arcuate radial surface with first and second arcuate portions and a third arcuate portion between the first and second arcuate portions that has a radius from the longitudinal axis of the pipe that is less than the radius of the first and second arcuate portions, and the second sleeve member having an inwardly-facing arcuate radial surface with first and second arcuate portions and a third arcuate portion between the first and second arcuate portions that has a radius from the longitudinal axis of the pipe that is less than the radius of the first and second arcuate portions.
