A thermally compliant grommet assembly for a combustor includes first and second shells spaced apart from one another and a grommet having a tubular portion projecting into a hole in the second shell and defining a bore in fluid communication through the first and second shells. The grommet further has an oblong flange portion extending circumferentially around and projecting outward from the tubular portion. The oblong flange portion is located between and is in sealing contact with the first and second shells. At least one of the first and second shells is constructed and arranged to move between cold and hot states and generally along a thermal displacement path. The oblong flange portion is generally elongated along the path to maintain sealing contact with at least one of the shells as the shells move between the hot and cold states.
