The STL brake cylinder adapter by AEROQUIP is a precision hydraulic fitting designed for professional brake system installations and repairs where reliable fluid transfer is non-negotiable. This straight adapter bridges the connection gap between 3 AN male ports and 3/8-24 inch inverted flare male couplings, making it an essential component for custom brake line fabrication, vehicle restoration, and high-performance hydraulic applications. Whether you're building a custom brake system for a hot rod, restoring a classic vehicle, or engineering a specialized hydraulic assembly, this adapter ensures proper fluid routing without compromise.
Manufactured from zinc-plated steel, this adapter delivers durability and corrosion resistance essential for underhood and frame-mounted environments where moisture and salt exposure are constant threats. The straight configuration minimizes turbulence and pressure drop while the 3/16-inch hardline compatibility ensures compatibility with industry-standard brake tubing specifications. AEROQUIP's engineering focus on dimensional precision—with a compact profile of 3 x 0.65 x 5.1 inches and minimal weight of 0.07 lbs—allows seamless integration into tight engine bays and complex brake layouts without adding unnecessary bulk. The male-to-male thread design supports both inlet and outlet configurations depending on your system's requirements.
Technicians, fabricators, and enthusiasts rely on this adapter for domestic and import brake system conversions, emergency brake upgrades, and modular brake circuit redesigns. Installation requires standard SAE flare-fitting tools and proper thread-sealant protocol to prevent fluid weeping at operating pressures. The zinc-plated finish requires no additional protection, though periodic inspection ensures the integrity of both fittings remains intact throughout the service life of your brake system. Pair this adapter with complementary hardline and flexible hose assemblies to build a complete, leak-free brake circuit tailored to your vehicle's specifications.
