An improved fluid collection device for mounting on cylinder-shaft assemblies, such as stuffing boxes, to control the leakage of fluids. The device comprises a flexible sleeve mounted to the end face of a stuffing box through a radial flange and having an upper cylindrical portion which extends along a length of the shaft reciprocating within the stuffing box. The sleeve includes a first inwardly extending radial portion which wipingly engages the surface of the shaft forming a collar therearound. The wiping collar forms a closed first chamber defined by the inner walls of the sleeve, the surface of the shaft, and the face of the stuffing box adjacent the shaft. Fluid communication is provided between the chamber and a fluid collection reservoir. A second partially closed chamber is similarly formed above the first chamber and is defined by the surface of the shaft, the cylindrical inner sleeve, the open circular end of which is spaced from the shaft, and the inwardly extending radial portion. The first and second chambers are connected to one another by drain apertures and the device itself fixed to end of a stuffing box by a set of universally adaptable clamps. Hydraulic fluid leakage from the stuffing box is collected by the first and second chambers and returned to the fluid reservoir.
