This sturdy 10 gallon (37.9 liter) high density polyethylene tank combines transportability with value. Designed with small to mid-size applications in mind this smaller version of our HydroCart is the ultimate in convenience. Simply connect to the Water Injector System™ and activate the Instant Valve Pro™. A flow indicator will tell you when all of the Injector valves have shut off and it is time to disconnect. The compact size of the HydroCart Mini is ideally suited to be taken on and off service vans as part of a battery maintenance program. Drop ships directly from supplier.
