#6 45-Degree Female Couple Fitting

The #6 45-Degree Female Couple Fitting is a precision hydraulic adapter designed for serious engine builders, fuel system integrators, and performance technicians who demand reliability under high pressure. This Fragola component solves a critical problem in custom fuel, coolant, and brake line routing: the need to change flow direction while maintaining a secure, leak-free connection without requiring bulky elbows or complex bend sequences. Whether you're laying out a race-spec fuel system, constructing a custom cooling circuit, or adapting incompatible line routes in a tight engine bay, this 45-degree female swivel coupling delivers the directional flexibility that stock configurations cannot provide.

Machined from aerospace-grade aluminum and finished in vibrant blue anodize, this fitting accommodates 6 AN (6/8") hose and features a 45-degree angle that reduces turbulence and pressure drop compared to tighter 90-degree bends. The female-to-female swivel design allows both connection points to rotate independently, eliminating hose-twist stress during installation and reducing vibration-induced fatigue cracks at weld points or connection terminals. Anodized aluminum construction provides corrosion resistance in wet engine compartments while maintaining a lightweight footprint—critical for weight-conscious builds where every tenth of a pound counts. The swivel mechanism ensures consistent flow characteristics across a range of operating temperatures and pressures typical in modern high-performance systems.

This fitting is ideal for fuel system builders transitioning from return-style carburetors to EFI fuel rails, drivers upgrading from mechanical to electronic fuel injection, and custom fabricators routing hoses through restrictive frame rails or firewall penetrations. The 6 AN standard ensures compatibility with -6 AN stainless braided hose, aluminum hard lines, and factory quick-disconnects found on most late-model performance engines. Installation is straightforward: thread both female connections hand-tight, then use a wrench on the fixed hex body while holding the swivel end to prevent over-torque. At just 0.02 lbs, it adds negligible weight to any fuel or coolant system while providing the directional control that prevents expensive rework and catastrophic hose failures on the dyno or street.
