The Goodway Shaft Lubrication fluid allows for fast, easy protection of flexible shafts in between uses. Simply fill the lubricator with water-soluble lubricant, connect the flexible shaft and attach a compressed air line [maximum 150 PSI (10 BAR) - quick connect fits Goodway air line #ASH-B50-A]. The flow of air and lubricant displaces water and coats the shaft core to protect it from harmful rust and corrosion. Lubricant flushes out with water when shaft is used again.
