An actuator is provided that includes a housing, a linear actuating shaft disposed within the housing, a piston coupled with the shaft, and a fluid barrier disposed on an end of the shaft and encircled by the piston. The piston is movable longitudinally between an extended configuration and a retracted configuration upon rotation of the shaft. The fluid barrier engages an inner surface of the piston preventing fluid communication across the fluid barrier. The fluid barrier has a shaft engaging side which receives the shaft and a fluid facing side. A cavity is formed between the piston and the fluid facing side and expands when the piston moves to the extended configuration and contracts when the piston moves to the retracted configuration. A port is disposed in the piston and extends from the cavity to external the piston thereby permitting fluid communication between the cavity and external the piston.
