Rubber seal 2C91312G02

O-ringcircularfor aircraft

JX-2C91312G02 is a precision-manufactured aerospace engine low-pressure turbine (LPT) disk axial seal, designed for CFM56 series turbofan engines. It seals the axial gap between the LPT disk and the turbine rear casing, blocking the low-temperature exhaust gas from entering the disk's axial cavity, which is critical for preventing the accumulation of exhaust contaminants, reducing the corrosion and wear of the disk's mating surface, and maintaining the structural stability of the LPT disk during long-term operation.
