AC PERFORMANCE -3 AN Male to 3/8 x 24 Adapter
Size: 3AN (3/8 x 24) male to 3/8 x 24 female inverted flare. Material: steel zinc. Application: connects stainless braided hoses to 3/16″ brake line. This adapter is best for everyday street use where a durable finish and corrosion resistance are important. It is a straightforward choice when you need a reliable connection between a braided hose and a small brake line.
Who it’s best for: wiring up a street build or restoration project needing a simple, robust flare adapter. Why selected: strong zinc-coated steel resists corrosion and offers a solid seal. Caution: not designed for high-heat or extreme racing environments where more exotic materials might be preferred.
Podavelle 3AN to 3/8-24 Inverted Flare Female
Size: AN3 male to 3/8×24 female inverted flare for 3/16″ steel brake lines. Material: 304 stainless steel. Application: adapt from 3/8″-24 inverted flare female to -3 AN flare male; ideal for frame-mounted terminations of 3/16″ steel brake lines. Use with -3AN hoses to connect calipers or wheel cylinders.
Who it’s best for: builders prioritizing stainless steel corrosion resistance in frame-mounted installations. Why selected: stainless construction offers long-term durability in exposed under‑car environments. Caution: ensure compatibility with your specific hose end and flare type to avoid leaks.
KRD PERFORMANCE M10 to -3 AN Hose End
Size: M10x1.0 male to AN3 (3/8″x24) PTFE hose end. Degree: Straight. Material: SUS304 stainless steel with brass olive insert. Application: works with 3AN PTFE brake hose/line; suitable for racing, car, truck, and motorcycle brake systems.

Buying Guide
What should you consider when choosing braided brake line fittings?
- Thread compatibility: Ensure the 3AN, inverted flare, and metric threads match your hose and brake components.
- Material choice: Stainless steel offers corrosion resistance; zinc-coated steel provides durability at a lower cost; consider climate and exposure.
- Hose end type: PTFE-lined hoses require compatible fittings and often specific end shapes (straight vs. angled).
- Application environment: Street-use vs. track use may justify different materials or finishes.
- Kit contents: Some products include only fittings; others provide hoses, banjos, bolts, and clips—plan for installation needs.
Practical questions buyers ask
- What is the difference between inverted flare and standard flare fittings?
- Are these fittings compatible with all braided brake hoses?
- Can I mix stainless steel fittings with zinc-coated ones?
- Do I need any special tools to install these adapters?
- Which combination is best for a track-day brake setup?
- What maintenance is required for stainless braided brake lines?
FAQ
- Q: Are these fittings designed for high-temperature brake systems? A: Several options are compatible with common race and performance setups, but consult the product specifics for temperature ratings.
- Q: Do the adapters require thread sealant? A: The included data suggests reliable seals with proper flare seating; avoid over-tightening to prevent damage.
- Q: Can I replace just a flare nut without replacing the entire hose? A: In many cases, adapters and nuts can be replaced if compatible, but verify fitment with your hose.
- Q: Is stainless steel better than zinc-coated steel for all environments? A: Stainless steel offers superior corrosion resistance, especially in moisture-prone areas; zinc-coated steel is typically more economical with adequate protection.
- Q: Should I choose a full hose kit or separate fittings? A: If you need a complete install with hardware, a kit like the Allstar option can simplify setup; for custom routing, individual fittings may be preferable.
- Q: How do I ensure leak-free connections? A: Use correctly sized flare nuts, clean seating surfaces, and follow proper torque guidelines to achieve a reliable seal.
