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.
Claims16
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;
- an arcuate radial-split gasket configured to be positioned between said first and second sleeve members and said fluid conduit;
- said gasket comprising a radial-split arcuate resilient outer gasket layer configured to provide a seal under compression and a separate radial-split arcuate resilient inner gasket layer configured to provide a seal under compression;
- said outer gasket layer having a resilient inner circumferential surface and a resilient outer circumferential surface;
- said inner gasket layer having a resilient inner circumferential surface and a resilient outer circumferential surface;
- said inner and outer gasket layers configured to be selectively disengaged from each other;
- and
- at least one of said inner circumferential surface of said outer gasket layer or said outer circumferential surface of said inner gasket layer comprising a plurality of separate circumferentially spaced apart resilient retaining protrusions radially interfacing between said inner and outer gasket layers at different circumferential locations about said longitudinal axis;
- at least one of said inner circumferential surface of said outer gasket layer or said outer circumferential surface of said inner gasket layer comprising a plurality of separate circumferentially spaced apart retaining cavities in said outer gasket layer or said inner gasket layer at different circumferential locations about said longitudinal axis that are correspondingly located about said longitudinal axis to said retaining protrusions;
- and
- said plurality of separate circumferentially spaced apart retaining protrusions radially interfacing between said inner and outer gasket layers at different circumferential locations about said longitudinal axis received within said plurality of separate circumferentially spaced apart retaining cavities in the other of said outer gasket layer or said inner gasket layer that are correspondingly located about said longitudinal axis to said retaining protrusions;
- whereby said plurality of separate circumferentially spaced apart retaining protrusions and said plurality of separate circumferentially spaced apart retaining cavities are configured to maintain angular alignment of said inner and outer gasket layers about said longitudinal axis.
