6AN Dry Break Fittings Black

The 6AN Dry Break Fittings Black are essential quick-disconnect couplings engineered for high-performance automotive fuel, coolant, and fluid transfer systems. These fittings serve builders and enthusiasts who demand zero-spill disconnects during engine bay modifications, turbo installations, and custom cooling loop setups. Dry break technology eliminates fluid loss when separating lines, protecting your engine bay from contamination and mess while maintaining system integrity during swap work or maintenance.

Machined from robust materials with a professional black finish, the 6AN dry break fitting design employs a spring-loaded poppet valve mechanism that automatically seals both male and female halves upon disconnection. The 6AN sizing (3/8-inch hose inner diameter equivalent) handles moderate flow rates suitable for fuel injection systems, auxiliary cooling circuits, and pressurized fluid transfer on street and track applications. The compact profile—measuring 3.75 inches in length—fits tight engine bays without fouling adjacent components, while the lightweight 0.21-pound construction minimizes unsprung weight and installation complexity.

Professional mechanics and DIY engine builders benefit most from dry break fittings when installing fuel rails on LS or K-series swaps, relocating radiators in chassis modifications, or connecting external oil coolers and transmission coolers. Installation requires standard AN hose and wrenches; the fittings accept industry-standard 6AN hose with compression-style barbed or JIC ends. Verify compatibility with your specific hose type and system pressure rating before installation, and always secure lines with proper clamps to prevent vibration-induced separation during operation.
