3an x 10 X 1.0 Bubble Flare Fitting

The FRAGOLA 3 AN x 10 x 1.0 Bubble Flare Fitting is a precision adapter designed to connect AN-series hardline tubing to metric bubble flare systems commonly found in high-performance hydraulic, fuel, and brake applications. This straight-through male-to-female adapter converts a 3 AN male port to a 10 mm x 1.0 metric female bubble flare connection, making it essential for custom fuel system builds, race car plumbing, and vintage restoration projects where mixed fitting standards must integrate reliably.

Manufactured from steel and finished in zinc oxide coating, this fitting provides corrosion resistance in both sealed engine bays and exposed environments. The bubble flare design—also called JIC (Joint Industry Council) flare—creates a predictable, repeatable seal when torqued to specification, eliminating the leak paths that can plague improperly adapted connections. At 0.1 lbs and compact in profile, the fitting adds minimal weight and footprint to system layouts where space is constrained. The straight configuration (no 45° or 90° offset) simplifies plumbing runs and reduces turbulence in fuel delivery or hydraulic pressure systems.

Technicians and builders working with AN hardline systems frequently encounter metric fasteners and fittings in imported components, OEM subassemblies, or European-market equipment. This adapter bridges that gap without requiring thread chasing or custom machining. Whether you're integrating a metric fuel filter, connecting to a bubble flare accumulator, or adapting a carbureted vintage engine to modern fuel injection plumbing, a quality AN-to-metric transition fitting is non-negotiable for system integrity and safety.

FRAGOLA is a recognized manufacturer of hard-anodized aluminum and steel hydraulic fittings trusted in racing, marine, and industrial settings where pressure retention and corrosion resistance are performance-critical. Individual adapters like this 650205 unit are sold singly, allowing precise inventory control and staged system builds.
