Product Description
The AN919-19D is a male-to-male reducer boss that adapts two different straight-thread port sizes in aircraft fluid systems. This brass fitting reduces a larger boss opening to accommodate a smaller diameter line connection. Conforms to Aeronautical Standard AN919 specifications for flared-tube interfaces.
Commonly installed in hydraulic system ports to step down line sizes while maintaining pressure integrity. Installation requires proper gasket or O-ring sealing per aircraft maintenance manual specifications. The reducer supports reliable fluid transfer between mismatched port diameters in confined engine bay and system applications.
