DOD-PRF-85734 - Synthetic Base Helicopter Transmission System Lubricating Oil
We perform lubricants quality testing by military specification DOD-PRF-85734, which covers a synthetic base helicopter transmission system lubricating oil. This lubricating oil is intended for use in helicopter transmissions and gearboxes for air, sea, and ground mobility equipment. These oils are designed for operation within the approximate bulk oil temperature range of -40 to 175 °C (-40 to 350 °F). This specification fulfills the military unique requirement for a high performance aviation transmission lubricant certified for use in the gearboxes and transmissions of all type/model/series helicopters designed to operate on a 5cS lubricant.
