Universal Fit Fragola -6AN x 5/8-18 Male Adapter-3/8 Tube I.F. - Black
This Fragola adapter connects -6AN braided hose to 3/8-inch tube with a 5/8-18 inverted flare male thread for leak-free plumbing in performance builds. It works in cars trucks and race vehicles managing fuel oil brake or nitrous lines under high pressure. Black anodized aluminum ensures corrosion resistance and sharp under-hood looks with 1000 PSI durability.
Key Features
- 6061-T6 Aluminum Construction: Lightweight strong material withstands 1000 PSI pressures in demanding fuel oil and brake applications
- Black Anodized Finish: Resists corrosion fuel residue and daily wear for reliable long-term use
- -6AN Swivel Male End: Enables 360-degree hose positioning for easy routing in crowded engine compartments
- 5/8-18 Inverted Flare Seal: Forms secure vibration-proof connection on 3/8-inch hardline tube enduring heat and stress
- Precision CNC Machining: Delivers tight tolerances for smooth flow rates and consistent pressure sealing

Fabrication
Fabrication parts and materials provide the raw components needed to build, repair, and modify custom exhaust systems, turbocharger plumbing, intercooler piping, fuel system lines, oil routing, and engine bay heat management on performance and competition vehicles. Stainless steel tubing, titanium tubing, aluminum charge piping, mandrel bends, pie cuts, flanges, merge collectors, V-band clamps, O2 sensor bungs, AN fittings, PTFE hose kits, braided fuel and oil lines, heat shields, and welding supplies are the backbone of any serious custom fabrication project. Professional fabricators, race team mechanics, and advanced DIY builders who want full control over exhaust routing, charge pipe layout, or fuel system plumbing choose raw fabrication materials rather than pre-bent kits because custom fabrication allows fitment solutions that no universal kit can accommodate. Brands including Vibrant Performance, Ticon Industries, Stainless Bros, Radium Engineering, Fragola, and DEI provide th...

Fittings
Automotive fluid system fittings are the hardware that connects hoses, hard lines, and components within fuel, oil, cooling, brake, power steering, and intercooler circuits, and the quality and correct sizing of these fittings directly determines whether a high-performance fluid system remains leak-free under the pressure, temperature, and vibration conditions that race and street performance environments produce. The AN fitting standard, derived from military Aircraft-Navy specifications, provides a consistent thread and flare geometry across fuel, oil, and hydraulic applications that allows interchangeability between brands and simplifies system design by providing a known thread engagement and sealing approach for every connection. Swivel fittings, bulkhead adapters, 45-degree and 90-degree elbow fittings, tee and union adapters, and reducer fittings allow performance builders to route lines through tight spaces and around obstacles while maintaining correct flow area without res...

Fragola
Fragola Performance Systems has manufactured AN fittings, PTFE hose, and plumbing hardware in the United States since 1979, supplying professional race teams and serious street builders who cannot afford a failed fuel or oil line at speed. The brand's manufacturing standards exceed SAE J1645 requirements, and every fitting is pressure-tested before leaving the facility in Clover, South Carolina. Builders who specify Fragola on a fuel system, oil cooler circuit, or brake line are choosing a product with a documented motorsport history across NASCAR, IndyCar, and NHRA drag racing.Popular UpgradesFragola's Series 3000 PTFE hose is the most popular choice for high-heat fuel system plumbing, rated to 450 degrees Fahrenheit and compatible with all fuel types including ethanol blends and methanol. Series 8000 and 8000LL hose assemblies suit high-pressure power steering and brake circuits up to 3000 PSI. Swivel seal fittings, 45-degree and 90-degree elbows, bulkhead adapters, and O-ring fac...
