ABSTRACT:
An arrangement is disclosed for securing together mating faces of hydraulic manifold blocks so as to securely seal aligned ports on the mating faces, the arrangement consisting of a slot having a sloping sidewall formed in each side of the manifold blocks adjacent to the mating surfaces, and includes respective clamping elements having contours adapted to engage the sloping sidewalls of slot pairs brought into juxtaposition when manifold block pairs are placed in position with the mating faces abutting each other. The clamping elements are drawn into the slots by means of threaded fasteners passing through the clamping element and mating position with respect to each other received in threaded bores in the respective manifold blocks, the interaction between the sloping slot and clamping element contours being such that the mating manifold faces are drawn tightly together.
