The Hawke modules are used together with a frame and a compression unit. As an innovator with focus on functionality, Hawke has invented a unique time-saving compression unit that makes retrofits possible. The end result is an optimum sealing solution for any application. The KM modules are used together with frames of the Hawke product K. The KM modules can also be used as a spare capacity, or as compensation modules. The modules have a depth of 30 mm and can accommodate diameters from 3.5 to 44 millimeters.
