Speedflow SF342-03-03 | -3 AN Male to 1/2" Male Inverted Flare Adapter

The Speedflow SF342-03-03 is a precision-machined -3 AN male to 1/2" male inverted flare adapter, designed to connect -3 AN braided line systems to components with a 1/2" inverted flare (double flare) port. The 1/2" inverted flare thread is commonly found on larger OEM master cylinders, brake boosters, and proportioning valves, making this adapter an essential fitting for AN brake line conversion builds on a wide range of performance and classic vehicles.

Applications

The SF342-03-03 is a key adapter for brake system upgrades and custom line fabrication, including:

  • Connecting -3 AN braided brake lines to master cylinders with 1/2" inverted flare outlet ports
  • Brake booster and proportioning valve connections on factory-style brake systems
  • Hot rod, muscle car, and classic vehicle brake line upgrades from steel tube to AN braided
  • Holden, Ford, Chevrolet, and GM vehicle brake system AN conversion builds
  • Any application bridging -3 AN braided lines to 1/2" inverted flare brake components

1/2" Inverted Flare — Larger Port Applications

The 1/2" inverted flare thread is typically found on the outlet ports of larger OEM master cylinders and brake boosters, where greater fluid volume is required. Compared to the more common 3/8"-24 and 7/16"-24 inverted flare standards, the 1/2" port is less frequently encountered but critical to get right when building a complete AN brake line conversion. The SF342-03-03 provides a clean, single-piece solution that eliminates the need for custom tube fabrication at these larger-port components.

For other AN to inverted flare sizes, see our SF340-03 (-3 AN to 3/8"-24) and SF341-04 (-4 AN to 7/16"-24) listings. Sold individually. Weight: 24g.
