The JetLaunch is the tool of choice for maintaining hydraulic and fluid handling systems. The unit shoots oversized foam projectiles to clean straight, curved and coiled tubes, pipes and pneumatic hoses 3/16″-2″ (4.8-51mm) I.D. It will even shoot the projectiles through couplings, valves and 90 bends to thoroughly clean the entire system. The JetLaunch uses compressed air to shoot oversized foam projectiles.
