I doubt it, as FJ predates O-ring chains by a couple of decades!
An O-ring chain would not, in any case, be of much benefit in this application. They are intended for use in harsh environments, where the chain is exposed to contaminants such as dirt & water; their main use is for motorcycle drive chains. They do also incur a small power loss - one of the claims for DI's X-ring chains is that the power loss is less than for a comparable O-ring chain.
