The Fragola Engineered with precision and crafted from premium-quality steel, this bulkhead tee adapter is the top choice for racers, off-road enthusiasts, and car builders who demand leak-free connections, maximum durability, and unrivaled performance. Whether you're plumbing a fuel, brake, or steering system through a firewall or securing lines on a tube chassis, Fragola’s -3AN Steel Bulkhead Tee delivers unmatched reliability for your high-stakes applications. Here’s why this fitting is the best choice for your vehicle and how it outshines all other options on the market.
Why Fragola
- Superior Engineering and Durability: Fragola Performance Systems has spent years researching, testing, and perfecting their fittings to ensure they meet the highest standards. The -3AN Steel Bulkhead Tee is crafted from high-grade steel with a zinc-coated finish for corrosion resistance, ensuring long-lasting performance in the harshest conditions, from off-road races like the Baja 1000 to street performance builds. Unlike aluminum alternatives, steel offers greater strength and resistance to over-tightening, reducing the risk of distortion or leaks.
- Leak-Free Performance: Featuring a 37-degree JIC-style flare and 3/8"-24 thread, this fitting ensures a tight, secure connection every time. Fragola’s meticulous design minimizes the risk of leaks, even under high-pressure fluid transfer, making it ideal for fuel, brake, or steering systems.
- Versatile Applications: Designed to pass connections through firewalls or secure hoses on tube chassis, the -3AN Bulkhead Tee is perfect for motorsports, off-road racing, and custom builds. It’s trusted in extreme events like the King of the Hammers, Dakar Rally, and Formula SAE, proving its reliability across diverse applications.
- Precision Manufacturing: Proudly made in Fragola’s family-owned facility in Southington, Connecticut, 99% of Fragola’s products, including this steel bulkhead tee, are manufactured in-house to ensure uncompromising quality. The company’s commitment to American-made components guarantees consistency and performance.
- Outperforms Competitors: Unlike generic fittings, Fragola’s bulkhead tee is designed with J-gauge threads and a one-piece construction for enhanced strength. Its steel composition outperforms aluminum fittings in high-torque scenarios, preventing damage during installation and ensuring a secure fit.
