314-04 -4 Male to M12 Banjo

Speedflow SF314-04 | -4 AN Male to M12 Banjo Fitting

The Speedflow SF314-04 is a precision-machined -4 AN male to M12 banjo fitting, designed to provide a direct, compact connection between a -4 AN male port and an M12 banjo bolt in high-performance brake and hydraulic line assemblies. Offering greater flow capacity than the -3 AN 314-03 variant, the SF314-04 is the preferred choice for larger caliper setups and master cylinder configurations requiring increased fluid volume.

314-04 vs 314-03 — Choosing the Right Size

The Speedflow 314 series is available in both -3 AN (314-03) and -4 AN (SF314-04) configurations. The -4 AN variant provides a larger internal bore for increased brake fluid flow, making it the better choice for high-displacement master cylinders, larger multi-piston calipers, or any system where maximising fluid volume and pedal response is a priority. If your system uses -3 AN lines, see our 314-03 listing.

Note: M12 banjo bolts are available in both M12 x 1.0 and M12 x 1.25 thread pitches. Always verify the thread pitch of your component’s banjo port before selecting a banjo bolt. See our SF301-04 (M12 x 1.0) and SF302-04 (M12 x 1.25) banjo bolt listings for compatible fasteners.
