Claim:
1. A kit to assemble on a tubular, comprising: a rotating element comprising a bore configured to receive the tubular therethrough, the bore including an interior groove, wherein the rotating element is configured to rotate relative to the tubular, when the tubular is received through the bore; a stop collar having a bore, a retainer portion configured to be received within the interior groove of the rotating element, and one or more first fingers extending along the bore of the stop collar; and a sleeve sized to be received onto the one or more first fingers to capture the one or more first fingers between the sleeve and the tubular when the stop collar is received on the tubular, such that an interference fit is formed between the one or more first fingers and the sleeve, wherein the sleeve is configured to expand when received onto the one or more first fingers of the stop collar when the stop collar is received around the tubular, such that an elasticity of the sleeve causes the sleeve to apply a radially-inward gripping force onto the one or more first fingers.
