Speedflow SF341-04 | -4 AN Male to 7/16"-24 Male Inverted Flare Adapter

The Speedflow SF341-04 is a precision-machined -4 AN male to 7/16"-24 male inverted flare adapter, designed to connect -4 AN braided line systems to components with a 7/16"-24 inverted flare (double flare) port. A step up in flow capacity from the -3 AN 340-03 variant, the SF341-04 is the preferred choice for -4 AN brake and hydraulic systems interfacing with OEM or factory-style 7/16"-24 inverted flare components.

• Connecting -4 AN braided brake lines to OEM master cylinders with 7/16"-24 inverted flare ports
• Brake proportioning and bias valve connections on factory-style brake systems
• Hot rod, muscle car, and classic vehicle brake line upgrades from steel tube to AN braided

7/16"-24 Inverted Flare — Common on US & Australian Performance Vehicles

The 7/16"-24 inverted flare is a widely used OEM brake line thread standard across American muscle cars, hot rods, and many Australian performance vehicles. When upgrading from factory steel brake tubing to -4 AN braided lines, the SF341-04 provides a clean, single-piece solution that eliminates the need for custom tube fabrication. It bridges the gap between the AN aftermarket and OEM inverted flare standards in one compact, precision-machined adapter.
