Mobil Industrial Lubricants designs hydraulic oils for excellent compatibility with a wide range of seal materials. Chemical compatibility guide This chart is intended as a general guide and details the suitability of elastomers in various chemicals and fluids. Skydrol. This is achieved through the balanced formulation approach where the optimum base oils and additives are selected. There is little value investing in using premium hydraulic oils such as the 3djh ri 7khuh fdq eh frqvlghudeoh gliihuhqfhv ehwzhhq wkh uhfrpphqgdwlrqv iurp frpsrqhqwv vxssolhuv 6r li lq grxew frqwdfw wkh ioxlg vxssolhu ru gr vshflilf whvwv $ Expl- Butyl is not suitable for use with petroleum products, but is an excellent inner liner for phosphate-ester base hydraulic fluids. The hydraulic fluid is the pressurized liquid used to transmit the power needed to operate an aircraft and is either liquid or oil. Fyrquel Fluids Description & Application. Petroleum oil hydraulic system seals of neoprene or Buna-N are not compatible with Skydrol and must be replaced with seals of butyl rubber or ethylene-propylene elastoiners. COMPATIBILITY WITH MATERIALS When using hydraulic fluids containing a synthetic oil the compatibility with sealing materials, plastics or paints has to be examined. ROYCO 782 is a red - colored synthetic hydraulic fluid developed to meet the severe duty demands of today's military and industrial equipment.
