An industrial vibrator for imparting vibrations which cause the flow of bulk particulate matter. The industrial vibrator is comprised of a housing and a reciprocating piston vertically movable within the cylinder bore of the housing. The piston is driven by compressed air causing the piston to rapidly and repeatedly strike a striking plate formed by the bottom of the housing thereby imparting vibrations to a hopper or bin to initiate and maintain movement of bulk particulate material. The striking end of the piston has a threaded bore for receiving a reciprocally threaded extension of an elastomeric tip so that the elastomeric tip is fixedly attached to the piston. The elastomeric tip reduces the decibel noise level caused by the piston's repeated impacts on the striking plate to levels acceptable under industrial safety and comfort standards. The durometer rating of the elastomeric tip is between 65 and 75 to withstand the frictional heat and disintegration resulting from repeated impacts against the metal striking plate.
