Alm. Breather Tank Kit 3-1/8 Dia x 11-1/2 AOL

The Alm. Breather Tank Kit 3-1/8 Dia x 11-1/2 AOL (MPN 85455) by MOROSO is a precision-engineered aluminum breather tank assembly designed for high-performance and tactical vehicle platforms. This component effectively manages crankcase vapors and pressure regulation, which is critical for maintaining engine longevity and preventing oil carryover in demanding operational conditions. Whether deployed in law enforcement pursuit vehicles, military support convoys, or specialized tactical transport, a properly functioning breather system preserves engine integrity under sustained acceleration and variable terrain.

Manufactured from lightweight aluminum, the 3-1/8-inch diameter tank with an overall length of 11-1/2 inches provides efficient vapor separation while minimizing weight—a critical design consideration in fuel-efficient tactical vehicles. The breather tank kit integrates seamlessly into closed-loop crankcase ventilation systems, reducing atmospheric emissions and preventing contamination that compromises turbocharger efficiency and intercooler function. MOROSO's engineering ensures positive pressure relief and negative pressure management, protecting engine seals and gaskets from stress failure during high-boost or extended idling scenarios common in tactical operations.

Field operators and powersports enthusiasts rely on this breather tank kit for reliable crankcase regulation across temperature extremes and duty cycles. Installation requires routing to existing PCV pathways, ensuring compatibility with various vehicle systems. This product is ideal for those who demand performance and reliability in challenging environments.
