McGill Hose utilizes Ultra Clean Technologies on every hydraulic hose it fabricates, to eliminate FOD – Foreign Object Debris from getting into your hydraulic equipment. This process offers a fast, less invasive way to clean contaminated hydraulic lines by shooting a projectile through the hose or tube assembly with a pneumatic launcher. The Ultra Clean Projectile strips out internal contamination, removing dirt, gunk and oil, leaving less opportunity for your equipment to fail due to FOD.
