The Pipistrel 5057054 is an aerospace-grade sealing O-ring used in various Pipistrel aircraft systems, typically for fuel, hydraulic, pneumatic, or mechanical sealing applications depending on installation point.

It is designed as a precision elastomer sealing element that prevents fluid or air leakage between mating components under vibration, temperature variation, and pressure cycling typical in light aircraft operation. In Pipistrel aircraft, O-rings like this are commonly used in engine accessories, fuel system fittings, landing gear components, and control system assemblies.

Material specification is generally an aviation-grade elastomer (often nitrile or fluorocarbon depending on sub-application) selected for compatibility with aircraft fluids and environmental exposure. Exact dimensions and compound can vary by installation standard and aircraft variant.
