Turbo Oil Drain Back Flange 10an - Black

The Turbo Oil Drain Back Flange 10AN - Black by EARLS is a precision adapter fitting designed to redirect oil flow from turbocharger installations back to the engine oil pan. This component solves a critical cooling and circulation requirement for turbocharged engines, particularly T25, T28, T30, and modern 2024 turbo applications. Oil drain fittings prevent turbo heat soak and bearing damage by ensuring consistent oil return, making this flange essential for any serious turbo build or upgrade.

This drain flange features a straight-threaded design with a 10 AN male outlet, providing reliable connections to standard aftermarket oil pan drain ports and line systems. Constructed from lightweight aluminum and finished in black anodized coating, the flange resists corrosion and thermal degradation while maintaining structural integrity under high-heat turbo environments. The compact profile (1.8 x 1.05 x 4 inches) allows flexible installation geometry, and the minimal weight (0.07 lbs) ensures no impact on engine balance or mounting stress.

Engine builders, turbocharged vehicle owners, and performance shops rely on EARLS oil drain flanges for OEM-level reliability and fitment. The 10 AN connection accommodates standard braided hose sizes used in modern turbo return lines, simplifying sourcing and compatibility. Whether upgrading a stock turbo installation or custom-building a high-performance engine, this adapter ensures proper oil circulation and extended turbocharger service life.
