Abstract
A hydraulic leak detection apparatus includes a detector body having a bore therethrough configured to receive a cylindrical hydraulic conduit through the bore. The detector body may be eccentrically distributed relative to a central bore axis so as to define a laterally protruding portion of the detector body. The laterally protruding portion of the detector body may have a laterally extending body passage defined therein communicated with the bore. The detector body may have at least one planar side configured to engage an end face of a hydraulic nut attached to the cylindrical hydraulic conduit. A leak detection sensor may be disposed at least partially in the laterally protruding portion of the detector body and communicated with the laterally extending body passage. The laterally extending body passage may be configured to convey hydraulic fluid introduced thereinto through the laterally extending body passage and into engagement with the leak detection sensor.
