Push-In Breather Cap - Orange

The PROFORM Push-In Breather Cap in orange is a steel engine breather designed for simple push-in installation into a 1-1/4 inch hole. Featuring the iconic Chevy Bowtie logo and durable orange powder-coat finish, this breather cap combines functional crankcase ventilation with classic muscle car aesthetics. The steel construction and corrosion-resistant coating ensure reliable performance across extended use cycles, whether on the street or the strip.

Push-in breather caps eliminate the need for threaded fasteners, reducing installation time and eliminating stripped hole concerns common with screw-type fittings. The round design provides unobstructed airflow, allowing crankcase pressure to vent safely and preventing oil leakage from gasket seals and breather tubes. Orange powder coating resists fade and corrosion better than painted alternatives, holding its color through engine bay heat cycles and thermal stress. Weighing just 0.27 pounds, this breather integrates seamlessly into existing engine bay layouts without adding weight.

This cap is engineered for small-block and big-block Chevrolet applications where OEM or custom crankcase ventilation is required. Builders and restorers standardize on push-in breathers for their reliability and simplicity—no gasket surface prep, no torque specifications, no potential for over-tightening. The iconic Bowtie badging appeals to enthusiasts who value authenticity and marque fidelity in their engine compartment details.

PROFORM breathers are OEM-compatible replacements and performance upgrades used across street, strip, and show applications. The bright orange finish makes the cap visible during engine bay inspections and serves as a quick reference point for checking breather tube condition and routing.
