Hartzell Propeller o-ring lubrication recommendation

Anyone have a recommendation for lubrication of the prop o-ring when installing a Hartzell constant-speed prop?
 
Sure thing.

Unless dictated otherwise by technical data, its generally safe to use the same fluid the system uses as oring lube. Engine oil, hydro, and in the case of fuel, Vaseline/petrolatum.
