EXXON HYJET IV-APLUS
Exxon HyJet IV-Aplus is a superior quality, fire-resistant phosphate ester hydraulic
fluid designed for use in commercial aircraft. This product is an advanced Type IV
fluid and offers many of the performance capabilities of Type V fluids, including high
temperature stability, low density, and rust protection. It is superior to all other
Type IV fluids in these respects. Exxon HyJet IV-Aplus meets the specifications
of all major aircraft manufacturers and SAE AS1241.
MOBIL AVIATION GREASES
Mobilgrease 28 is manufactured from a synthesized hydrocarbon fluid and
a nonsoap thickener. Its consistency is between an NLGI No. 1 and No. 2 grease.
It offers outstanding performance over wide temperature ranges, with the excellent
retention and resistance to high-temperature degradation. In addition, it resists
water washing, provides superior load-carrying ability, reduces frictional drag, and
prevents excessive wear. Mobilgrease 28 exceeds the requirements of U.S. Military
Specification MIL-G-81322E Grease (Grade A), General-Purpose, Aircraft, and
meets the requirements of U.S.
Military Specification DOD-G-24508A (Navy) for shipboard auxiliary machinery. It can
be designated U.S. Military Symbol WTR and NATO Symbol G-395. Other tests show
that Mobilgrease 28 prevents friction oxidation (fretting) and lubricates rolling element
bearings under conditions of high speeds and temperatures. It has also shown superior
ability to lubricate heavily loaded sliding mechanisms, such as wing flap screwjacks.
Mobil Aviation Grease SHC 100 is a high-performance grease which combines
a synthesized hydrocarbon base fluid with a lithium complex soap thickener.
The thickener system provides a high dropping point, excellent resistance to water
wash, and a tenacious structural stability. The unique physical properties of the
synthetic base oil, combined with selected additives, provide outstanding protection
against wear, rust, corrosion, and high-temperature degradation. The wax-free
feature of the synthetic base oil allows for low-temperature mobility/pumpability
and very low starting and running torque values. Also, the traction property of the
synthetic base fluid is consider-ably lower than mineral oil, allowing for temperature
reductions in the load zone of rolling element bearings.
