Mityvac Fluid Evacuators are used to remove fluids from vehicles and machinery, including engine oil from crankcases, brake fluid from master cylinders, gear oil from transmission cases, coolant from cooling systems, and steering fluid from pump reservoirs. Available in four models that are either compressed-air or manual-pump operated and have holding capacities ranging from 1.9 quarts to 2.3 gallons, these lightweight, portable units feature polyethylene reservoirs that are impervious to chemicals, rust, and corrosion; automatic flow controls to prevent overfilling; and pressure-relief valves for added safety.
