10-101949-012 is a mounting flange gasket designed for Amphenol PT and PC miniature cylindrical connectors. This gasket provides a sealing interface between the connector shell and the mounting surface, ensuring environmental protection and mechanical stability. The gasket is available in multiple shell sizes (6, 8, 10, 12, 14, 16, 18, 20, 22, and 24) with precisely specified dimensions for inner diameter (R) and outer diameter (S), both with ±0.010 inch tolerances, and a thickness (T) of ±0.008 inch. The gasket thickness is standardized at 0.024 inches across all sizes, providing consistent sealing performance. These gaskets are commonly used in aerospace, military, and industrial applications where reliable connector sealing and vibration resistance are essential.
