Parker Aerospace

Parker Hannifin's division Parker Aerospace develops components and subsystems for civil aviation, defense, and select aerospace applications. In these environments, the requirements for operational reliability, weight optimization, material selection, traceability, and documentation are significantly higher than in many industrial installations.

The solutions are typically used in critical aircraft systems, where component performance, certification, and service life have a direct impact on safe operation and maintenance intervals.

What does Parker Aerospace typically cover? 

Parker Aerospace is not a single product type, but an ecosystem of components for the aircraft's fluid systems and associated installations. Depending on platform and approvals, this may include:

  • Fittings and pipe/hose connections for hydraulics, fuel, and lubricants, where correct sealing and vibration resistance are critical.

  • Valves and regulation for controlling flow and pressure in systems with varying loads and temperatures.

  • Filtration to protect pumps, actuators, and fuel systems against particles and water, improving component service life and uptime.

  • Seals and materials for aggressive media, high temperatures, and long service intervals.

Technical Requirements in Aerospace

Aerospace applications typically work with:

  • Strict certification requirements and documentation.

  • Material traceability and quality control.

  • High pressure and temperature variations.

  • Low weight combined with high strength.

  • Long service intervals and high operational reliability.

Therefore, component design, production, and testing are often subject to extensive standards and approval processes.

Typical Applications

In practice, the right component choices can be critical in, for example, hydraulics for landing gear and flight controls, fuel handling, and test and ground support equipment. Here, small tolerance deviations, incorrect material selection, or inadequate assembly are often enough to cause leakage, pressure drops, or premature wear.
