In an independent hose-cleanliness test, a 10-second air blow still left 52,827 particles 6 microns and larger per cc.
After Ultra Clean projectile cleaning?
511.
That’s over 99% fewer particles than the 10-second air blow in this test.
The takeaway is simple: blowing out a hose and cleaning the inner tube are not the same thing.
Contamination left behind after fabrication can travel with the replacement hose and enter the hydraulic system at installation. If compressed air is the last step in your process, it may be time to rethink what “clean” really means.
Cutting and crimping are not the last steps. Cleaning is.
