The M-Jet comes with a variable nozzle on the outlet of the nozzle. The M-Jet is to be used on jobs where the zero degree impact is not required. MJET will inject and proportion soaps, chemicals, or other liquids at high pressure without going through your pump, hose, gun or lance. The MJET can project liquids to vertical heights over 40 feet depending upon the capability of your pressure washer. It can be used with virtually any pressure washer, hot or cold for 1000 PSI to 6000 PSI.
