2C81035G02 is a precision aerospace component, compliant with AS9100D quality standards and FAA/EASA regulations, designed for large commercial turbofan engine lubrication systems.

It acts as an engine lubrication oil filter housing seal ring, forming a tight, stable seal between the oil filter housing and the engine lubrication module. This prevents lubricating oil leakage, which would reduce the oil pressure required for engine component lubrication and cooling, leading to excessive friction, component wear, or sudden engine failure.

Made from high-temperature-resistant, oil-resistant fluorosilicone rubber, it can withstand operating temperatures from -40°C to 220°C and long-term contact with aviation lubricants. Weighing only 0.08kg, it allows quick replacement during engine MRO overhauls, and is a key component for maintaining engine lubrication system reliability.
