Encapsulation sleeve gasket assembly with removable inner layer

A conduit coupling assembly configured to clamp to a fluid conduit oriented about a longitudinal axis comprising:

• a first arcuate sleeve member;
• a second arcuate sleeve member;
• a connecting assembly coupling the first sleeve member to the second sleeve member and configured to tighten said first and second sleeve members to a fluid conduit from a non-actuated position to a tightened position;
• a gasket ring configured to be positioned around a fluid conduit between said first and second sleeve members and the fluid conduit;
• said gasket comprising an outer gasket ring and a separate inner gasket ring;
• said outer gasket ring having an inner annular surface and an outer annular surface;
• said inner gasket ring having an inner annular surface and an outer annular surface;
• said inner and outer gasket rings configured to be selectively disengaged from each other;
• and
• said outer gasket ring having a maximum axial width and said inner gasket ring having a maximum axial width less than said maximum axial width of said outer gasket ring.

A gasket comprising:

• a radial-split arcuate outer gasket layer and a separate radial-split arcuate inner gasket layer orientated about a common longitudinal axis;
• said outer gasket layer having an inner circumferential surface and an outer circumferential surface;
• said inner gasket layer having an inner circumferential surface and an outer circumferential surface;
• said inner and outer gasket layers configured to be selectively disengaged from each other;
• and
• said inner circumferential surface of said outer gasket layer and/or said outer circumferential surface of said inner gasket layer comprising a plurality of circumferentially spaced retaining protrusions interfacing between said inner and outer gasket layers to maintain angular alignment of said inner and outer gasket layers about said longitudinal axis.
