[0002] The application of aviation sealants is crucial for ensuring the structural tightness of aircraft, directly impacting aircraft safety and performance. The application process requires precise control to ensure the sealant effectively fills seams and gaps, preventing gas and liquid leakage. The sealing cap is a crucial component used to seal aircraft fasteners.
