ABSTRACT:
A fluid-handling device includes first and second mating plates. The first plate includes a central groove and a secondary groove surrounding the central groove. The second plate includes a complementary central groove that forms a main bore with the central groove of the first plate. A first seal disposed between the first and second plates seals between the main bore and the secondary groove. A second seal is disposed between the plates and surrounding the first seal. A vacuum communicates between the secondary groove to draw away fluid that may leak from the main bore past the first seal. The forces in the secondary groove due to the vacuum aid in securing the second plate to the first plate. A sensor can be tapped into the vacuum line to immediately sense whether any fluid has leaked past the first seal.
