Abstract: A fluid isolator includes a primary outlet port adapted-to be coupled to a hydraulic device; a bleed valve having a first and a second position; a first line in fluid communication with the primary outlet port and the bleed valve; a first and second one way valve located in the first line inhibiting the flow of fluid toward the primary outlet port; a primary gauge port adapted to be coupled with a pressure gauge; and a second line in fluid communication with the primary gauge port and a portion of the first line located between the first and the second one way valve; wherein the bleed valve is switchable between the first and second position to permit the flow of fluid from the primary outlet port to a region of lower fluid pressure.
