Abstract: A flush and fill tool is configured for releasable mating engagement with a bulkhead mounted connector unit which has an optical contact chamber containing optical fluid. The unit has an outer shell with an open forward end containing a seal assembly designed for sealed engagement with a corresponding seal assembly at the forward end of the mating connector unit. An optical fluid fill reservoir and a capture reservoir for used optical fluid located in the housing are associated with a fill pin and a return pin, respectively, which extend through aligned bores in the seal assemblies into the optical contact chamber in the mated condition. A spring loaded plunger engaged in the fill reservoir injects optical fluid from the fill reservoir through a passageway through the fill pin and into the optical contact chamber, ejecting used oil from the chamber through a passageway in the return pin into the capture reservoir.
