This hydraulic fluid is blended with highly refined mineral based oils
and modern additive technology to provide protection against rust, wear,
demulsibility, and to afford greatly improved viscosity - temperature
characteristics as well as enhanced oxidation – corrosion resistance.
MIL-DTL-17111C SCOPE:
This specification covers a class of fluid for use in the hydraulic transmission
of power.
MIL-DTL-17111C Intended Use
The fluid covered by this specification is a medium to be used in
connection with hydraulic transmission power.
MIL-DTL-17111C
Subject term listing
Subject terms listings are Hydraulic
mineral oil,
petroleum, and icresyl phosphate.
MIL-DTL-17111C Materials
The fluid shall consist of mineral oil products plus 1.0 ± 0.1 weight
percent of tricresyl phosphate conforming to TT-T-656 and approved additive materials for
improving the finished product with respect to the viscosity-temperature and lubricating
characteristics, resistance to oxidation, and protection of metal parts against corrosion.
MIL-DTL-17111C Suitability
The fluid shall be suitable for use in hydraulic systems involving
mechanical or fibrous type filters or centrifugal purification. It shall be noncorrosive to bearings
and hydraulic systems and shall not cause clogging of oil screens or valves. The fluid shall
remain homogeneous over the temperature range of -34 °C to 4 °C.
MIL-DTL-17111C Low temperature turbidity
A dry sample of the fluid shall be stored at a
temperature of 37 °C for not less than 72 hours. After that time at the storage temperature, the
fluid shall show no evidence of gelling, crystallization, or separation, and shall develop a turbidity
not greater than that exhibited by a standard suspension of barium sulfate in water.
MIL-DTL-17111C Rust prevention
The transmission fluid shall prevent the formation of rust.
MIL-DTL-17111C Corrosion and oxidation stability
The finished fluid must encompass both
resistance to oxidation and protection of metal parts against corrosion.
MIL-DTL-17111C Packaging
When packaging of materiel is to be performed by
DoD or in-house contractor personnel, these personnel need to contact the responsible packaging
activity to ascertain packaging requirements. Packaging requirements are maintained by the
inventory control point’s packaging activities within the military service or defense agency or
within the military service’s system command. Packaging data retrieval is available from the
managing military department’s or defense agency’s automated packaging files, CD-ROM
products, or by contacting the responsible packaging activity.
