The Improved EZ Greaser Flow Divider Valve Assemblies from Graco Inc. are compact and ideal when space is tight and weight matters. The EZ Greaser assemblies use compact series progressive (CSP) divider valves to add centralized lubrication to trucks, tractors, and trailers. They are 30 percent lighter than the previous generation, the company says. Users can safely and easily grease many points from one fitting, shortening the amount of time spent greasing and ensuring no grease points are overlooked.
