S9413-554WE - O-Ring
Description
Part number S9413-554WE is a fluorocarbon elastomer O-ring seal manufactured by Wencor, LLC for aerospace sealing applications. This precision-molded O-ring is designed to provide reliable static and dynamic sealing performance in aircraft pneumatic, hydraulic, lubrication, and fuel systems operating under demanding environmental conditions.
Manufactured from high-performance fluorocarbon material (commonly Viton®/FKM equivalent), the seal offers excellent resistance to aviation fuels, hydraulic fluids, lubricants, ozone, heat, and chemical exposure. The material maintains sealing integrity across a broad temperature range and is suitable for long-term aerospace service.
This FAA/PMA-approved replacement component is identified for use on multiple Boeing aircraft platforms including the B737, B747, B757, and B767 series.
