Breather Can #12 Ports

The Peterson Fluid Breather Can #12 Ports is a precision-engineered crankcase ventilation reservoir designed for high-performance and tactical vehicle platforms requiring reliable pressure management and fluid separation. Built for military, law enforcement, and serious enthusiasts who demand systems that function flawlessly under extreme conditions, this breather tank eliminates crankcase pressure buildup while capturing oil mist and moisture—critical for maintaining engine longevity and operational reliability in demanding field environments.

Constructed from lightweight aluminum with natural finish, the Breather Can #12 Ports features dual 12 AN female inlet ports and a 6 AN drain plug, allowing flexible plumbing configurations for complex engine bay layouts. The T-bolt mounting clamp provides secure, vibration-resistant installation on standard engine mounts, while the 1-quart capacity and 4.5-inch diameter x 7-inch height design fit compact tactical vehicle installations without sacrificing separation efficiency. The 12-port configuration ensures maximum flow capacity and pressure relief across multiple vacuum and boost lines, essential for turbocharged or supercharged platforms where single-port designs create flow restrictions and inconsistent pressure regulation.

This breather tank benefits operators running modified engines, high-displacement platforms, or vehicles subjected to extended duty cycles where standard factory crankcase systems fail to manage vapor load. Installation requires basic mechanical knowledge and compatible AN hose fittings; mounting clearance should be verified in confined engine compartments common to armored or purpose-built tactical vehicles. The aluminum construction resists corrosion from harsh field conditions while remaining lightweight—a critical consideration for platforms where every pound impacts mobility and fuel economy during extended operations.
