Multifunction valves, also known as multifunction oil service adapters (MFOSA), from Parker Aerospace have been customized to dozens of applications over three decades in commercial jets, military aircraft, regional aircraft, and more. The valve can allow for gravity fill, remote fill, and even remote automatic overfill. These are typically on a gearbox on an engine, transmission, reservoir, or auxiliary power unit.

The multifunction valve is typically made of stainless steel to meet the strict fireproof requirement. Custom connections for a multifunction valve include unique flare or flareless fittings, and it can be flange mounted.
