Hose Fitting #12 Str. PTFE Black

The FRAGOLA Hose Fitting #12 Straight PTFE Black (model 680112-BL) is a precision-engineered hose end designed for high-pressure hydraulic and fuel line applications. This straight 12 AN fitting connects a 12 AN PTFE hose to a 12 AN female port, making it essential for custom fuel system builds, hydraulic brake conversions, and performance cooling circuits where reliability under extreme pressure is non-negotiable.

Constructed from aluminum and finished in black anodize, this fitting offers corrosion resistance while maintaining a lightweight profile—critical for race applications and vehicles where system weight impacts performance. The straight configuration eliminates bends at the connection point, reducing turbulence and potential leak points. PTFE hose compatibility ensures compatibility with modern fuel systems that demand compatibility with alcohol-blend racing fuel and extreme temperature swings. The 12 AN size—equivalent to -12 hose ID—handles flow rates typical of fuel injection and cooling systems without restriction.

This fitting serves drag racers, street rodders, off-road competitors, and performance enthusiasts building or upgrading fuel delivery and cooling systems. Whether upgrading from factory rubber hoses to braided PTFE for improved durability, or assembling a completely custom hydraulic circuit, the 680112-BL provides the straight-through connection needed at critical junction points. Sold as a single unit, multiple fittings may be required depending on your system configuration.

FRAGOLA fittings are recognized in the racing and automotive aftermarket for dimensional accuracy and consistency, ensuring reliable seal engagement when paired with proper hose assembly techniques and appropriate thread sealant or ferrule sealing.
