Poly Breather Tank w/12an Fitting

The Poly Breather Tank w/12AN Fitting from MOROSO (MOR85400) is a bolt-on overflow recovery system designed for high-performance engines and racing applications where crankcase ventilation management is critical. This compact polyethylene breather tank captures excess blow-by gases and fluid, preventing contamination of the engine bay while maintaining proper crankcase pressure. Tactical and motorsports professionals rely on breather tanks to protect engine internals and extend service life in extreme operating conditions.

Engineered for efficiency, this tank features a durable black plastic construction that resists corrosion and thermal degradation. The integrated petcock drain valve allows for controlled, mess-free fluid disposal during maintenance, while the 12 AN bulkhead inlet provides a secure, high-flow connection point for crankcase hose systems. The included breather element filters incoming air to prevent moisture and particulate contamination, ensuring optimal performance.

This breather tank is ideal for street-driven performance vehicles, off-road platforms, and competition engines that demand robust ventilation solutions. With a total weight of 1.22 lbs, installation adds minimal mass while delivering reliable overflow management in tight engine compartments. The 12 AN fitting accommodates standard motorsports hose sizes and quick-disconnect couplers, making integration straightforward.
