ELIMINATING AIR FROM THE SYSTEM ELIMINATING AIR FROM THE SYSTEM ELIMINATING AIR FROM THE SYSTEM ELIMINATING AIR FROM THE SYSTEM ELIMINATING AIR FROM THE SYSTEM All hydraulic fluid contains some dissolved air, usually about 10% by volume. Under increased pressure, the fluid will absorb much more air.
The easiest way to effectively reduce and possibly eliminate this problem is to use an adequate pipe thread sealer at all connections and fittings. While other pipe thread sealers may meet specifications, the methods which Barko uses are Teflon tape, and Locktite Teflon Thread Sealer.
