#4 Bulkhead Tee Fitting Black

The #4 Bulkhead Tee Fitting Black from FRAGOLA is a precision hydraulic and fuel system component engineered for custom automotive builds, performance modifications, and engine bay plumbing applications. Whether you're assembling a high-performance fuel delivery system, custom coolant routing, or hydraulic brake line architecture, this bulkhead tee fitting serves as a critical junction point for three-way line distribution. Built for mechanics and fabricators who demand reliability under pressure, this fitting eliminates the need for multiple adapters and reduces connection points that could compromise system integrity.

Manufactured by FRAGOLA, a leader in motorsports fluid system components, the #4 bulkhead tee fitting features precision-machined construction with a black anodized finish that resists corrosion and matches modern engine bay aesthetics. The tee configuration allows simultaneous connection of three separate lines, making it ideal for split brake systems, fuel rail distribution, or remote fluid reservoirs in drag racing and circle track applications. The compact 1.9 x 0.8 x 4.25-inch footprint and lightweight 0.04 lbs design minimize packaging constraints in tight engine compartments, while the threaded design ensures leak-free performance across temperature and pressure cycling. This fitting integrates seamlessly into AN-line systems common in modified, turbocharged, and supercharged vehicles.

Professional mechanics, drag racers, and street performance enthusiasts benefit most from this bulkhead tee fitting when designing custom fuel injection systems, auxiliary cooling circuits, or redundant brake line configurations. Installation requires proper thread sealant and torque sequencing to maintain system pressure without over-tightening aluminum threads. This fitting is compatible with standard #4 AN line adapters and works in both forced-induction and naturally aspirated engine bays. Its black finish provides visual integration with modern engine covers while maintaining full functionality in high-heat environments typical of modified vehicles.
