The FRAGOLA #3 Straight PTFE Hose End in steel is a precision fluid coupling component engineered for high-performance fuel and coolant systems in modified vehicles and race applications. This straight hose end serves as the critical junction between braided hose lines and engine block ports, carburetor inlets, fuel rails, or transmission cooler circuits. Whether you're building a high-horsepower street engine, turbo setup, or competition vehicle, this fitting delivers the leak-free, pressure-rated connection required in demanding automotive environments where standard rubber hose simply won't perform.
Constructed from solid steel with a PTFE (polytetrafluoroethylene) inner seal, the #3 straight hose end combines corrosion resistance with superior fluid compatibility across gasoline, diesel, coolant, and synthetic fluids. The straight configuration—as opposed to angled or 45-degree variants—suits applications where port alignment allows direct line routing, minimizing turbulence and pressure drop. FRAGOLA's precision engineering ensures consistent thread specification and hose barb dimensions, eliminating the fitment issues common with lower-grade alternatives. The compact form factor (1.1 x 0.7 x 4.15 inches) and lightweight design (0.06 lbs) make this fitting ideal for tight engine bays where space and weight savings matter in competitive builds.
Mechanics and engine builders rely on FRAGOLA hose ends for fuel system upgrades, custom cooling circuits, and transmission line modifications on platforms ranging from carbureted classics to turbocharged moderns. The #3 size accommodates standard -3AN braided hose (commonly used in fuel rails and cooler lines), making it compatible with most quality braided hose assemblies. Installation requires proper hose sizing, appropriate thread sealant on tapered connections, and careful torque sequencing to prevent thread galling—always consult system pressure ratings and ensure the complete line assembly matches your application's PSI requirements for safety and reliability.
