Mini Breather Tank 1.75in

The Mini Breather Tank 1.75in by ALLSTAR PERFORMANCE is a compact, clamp-on breather assembly engineered for high-performance engine builds where space is limited and crankcase vapor management is critical. Designed for 1.75-inch tube diameter installations, this mini breather tank serves engines that require effective air-oil separation without occupying excessive underhood real estate. Whether you're building a street rod, race engine, or custom automotive project, this breather solution provides reliable crankcase pressure relief while capturing oil mist before atmospheric venting.

Constructed from durable aluminum and finished in natural anodize, the Mini Breather Tank 1.75in features a 1.5-inch diameter body standing 6.75 inches tall with a 4-ounce capacity—ideal for containing oil vapors in tight installations. The tank includes a 1/4-inch NPT female inlet port for secure plumbing integration and comes equipped with an integrated breather element that filters crankcase gases while preventing liquid oil carryover into the intake system. The clamp-on design allows straightforward attachment to 1.75-inch tubes, eliminating complex mounting hardware and enabling quick service or repositioning during engine development and tuning cycles.

This mini breather tank is ideal for engine builders, vintage hot rod fabricators, and performance enthusiasts who demand compact, effective crankcase management in confined engine bays. Its aluminum construction resists corrosion, while the small footprint makes it compatible with custom frameup builds where conventional large-capacity breathers cannot fit. Installation is straightforward—connect the 1/4-inch NPT inlet to your engine's breather port, secure the clamp to your 1.75-inch tubing, and route outlet venting appropriately for your application. Whether for daily-driven customs or weekend race cars, the Mini Breather Tank 1.75in provides proven oil separation and pressure control for engines built to last.
