Positive Seal Vented Fitting -10 AN

The KEVKO OIL PANS & COMPONENTS Positive Seal Vented Fitting -10 AN is a precision aluminum component engineered for high-performance engine ventilation systems. This male AN fitting delivers a positive seal connection with built-in venting capability, eliminating the need for separate vent lines in crankcase evacuation and catch-can applications. The clear anodized finish provides corrosion resistance while maintaining visibility of the fitting's aluminum body in tight engine bay spaces.

Rated for -10 AN (⅝-inch) connections, this fitting accepts standard -10 hose and hard-line assemblies with reliable clamping force and zero weeping under pressure cycling. The vented design allows atmospheric equalization while the positive seal mechanism prevents backflow and maintains system integrity during engine acceleration and deceleration. Aluminum construction keeps weight minimal without sacrificing structural integrity, a critical advantage in competition and purpose-built engine builds where every fraction of a pound matters.

This component serves builders of high-horsepower, forced-induction, and naturally aspirated engines requiring sophisticated PCV and catch-can integration. Street rods, drag racing platforms, performance truck builds, and custom engine combinations benefit from KEVKO's purpose-built approach to crankcase management. The positive seal fitting eliminates guesswork in plumbing complex ventilation systems, ensuring consistent system pressure and preventing oil vapor condensation in intake runners.

KEVKO's reputation in professional engine building rests on meticulous attention to flow paths, seal integrity, and long-term reliability under thermal cycling and sustained high RPM operation. The -10 AN sizing integrates seamlessly with industry-standard hose, fittings, and catch-can configurations, allowing flexible system design without adapter complications.
