Brake Adapter -4 to 7/16

The Brake Adapter -4 to 7/16 (EARLS MPN 989548ERL) is a precision hydraulic line fitting engineered for high-performance brake and fuel system applications in tactical vehicles, law enforcement pursuits, and military platforms. Built to military-grade standards, this straight adapter converts 4 AN male ports to 7/16-24 inverted flare female connections, enabling seamless integration between incompatible brake line standards without compromise. Operators and technicians depend on this fitting to maintain system integrity under extreme braking demands, whether in patrol vehicles, armored platforms, or field-deployed equipment requiring reliable pressure transfer.

Constructed from zinc-plated steel, the Brake Adapter -4 to 7/16 resists corrosion and maintains structural integrity across temperature extremes and high-pressure cycling—critical for systems operating at 1,500+ PSI. The inverted flare design creates a metal-to-metal seal that eliminates vibration-induced leakage common in crimped or ferrule-based connections, while the 1/4-inch hardline bore supports full system flow with minimal turbulence. Zinc plating provides extended service life in harsh environments, from desert operations to coastal salt-air exposure, without sacrificing connection reliability or seal performance.

Law enforcement fleet mechanics, military vehicle maintenance teams, and tactical equipment specialists benefit most from this adapter when retrofitting brake systems to accommodate mixed AN and SAE specifications. Installation is straightforward—thread the male end into any 4 AN female port and hand-tighten the female flare connector to your 7/16-24 hardline, then secure with a wrench for leak-proof operation. Compact dimensions (2.2 x 0.65 x 2.5 inches) allow routing in tight engine bays, while the 0.08 lb weight makes it ideal for weight-critical mobile platforms. Verify your existing line thread pitch and brake system pressure rating before installation to ensure full compatibility.
