10an Male Valve Cover Oil Cap Aluminum Black

The 10 AN Male Valve Cover Oil Cap from REDHORSE PERFORMANCE is a precision-engineered adapter fitting designed for builders and enthusiasts who demand reliable AN-threaded connections on custom engine bay setups. This fitting solves a common integration challenge: connecting modern 10 AN hose systems to original equipment oil cap ports without modification or compromise. Whether you're building a street machine, race engine, or custom circulation system, this adapter provides the secure, leak-free interface needed for performance and durability.

Constructed from aluminum and finished in black anodize, the 10 AN Male Valve Cover Oil Cap features a 10 AN male thread on one end and an OE-compatible oil cap fitting with integrated O-ring on the other. The black anodized finish provides corrosion resistance and a professional appearance while protecting against oxidation in high-heat engine environments. The O-ring seal design ensures positive fluid containment without relying on external clamps or secondary fasteners, reducing assembly complexity and potential leak points. This 925 Series adapter is built to REDHORSE's quality standards, delivering consistent thread engagement and reliable pressure retention across typical street and moderate performance applications.

This fitting is ideal for engine builders, custom fabricators, and powersports enthusiasts who are converting or upgrading existing OE oil cap systems to AN plumbing. Installation is straightforward: thread the 10 AN male end into your hose line or manifold component, then seat the OE-compatible end into the original oil cap opening—the integral O-ring creates a hydraulic seal without additional tools. Compatible with any engine featuring a removable oil cap and requiring 10 AN outlet connectivity, this adapter is a compact, lightweight solution that weighs just 0.19 pounds and occupies minimal engine bay real estate, making it perfect for tight custom installations.
