Positive Seal Vented Fitting -16 AN

The Positive Seal Vented Fitting -16 AN Male is a precision-engineered breather component designed for serious engine builders, race teams, and high-performance enthusiasts who demand reliability in critical crankcase ventilation systems. This aluminum fitting serves as the interface between your custom oil pan breather system and hose routing, ensuring positive pressure control while maintaining proper crankcase evacuation. Whether you're running a carbureted street engine, a supercharged drag racing platform, or a naturally aspirated track-focused build, this vented fitting prevents oil vapor blowby and maintains consistent engine bay cleanliness.

Manufactured by KEVKO Oil Pans & Components, a brand trusted by engine shop professionals for over three decades, this -16 AN (JIC) male adapter is machined from aerospace-grade aluminum and finished in clear anodized coating for superior corrosion resistance and durability. The positive seal design guarantees a leak-free connection without thread sealant, using JIC 37-degree flare geometry that creates a metal-to-metal contact point—critical for high-vacuum or pressurized crankcase applications. The vented feature allows controlled airflow while the compact 1.88 x 1.75 x 2-inch form factor integrates seamlessly into tight engine compartment layouts common in custom race cars, restorations, and modern turbocharged platforms.

This fitting is ideal for builders upgrading to aftermarket or custom oil pans that require external breather plumbing, particularly in applications where factory breather systems have been deleted or relocated. Installation requires standard AN hose and fittings compatible with -16 JIC male threads; the lightweight 0.21-pound component adds minimal weight while improving crankcase management efficiency. Commonly paired with vacuum-operated PCV systems, catch cans, and remote breather tanks, the Positive Seal Vented Fitting -16 AN ensures your engine breathing solution performs under all operating conditions—from idle cruising to full-throttle competition.
