Universal Drain Valve -8 AN ORB with 1/8in Port

The Universal Drain Valve -8 AN ORB with 1/8in Port is an essential component for serious engine builders, performance enthusiasts, and custom vehicle modifiers who demand precise fluid management in high-performance cooling and lubrication systems. This compact, lightweight drain valve serves as a critical integration point in custom cooling loops, oil filtration setups, and auxiliary hydraulic circuits where space is limited and reliability is non-negotiable. Whether you're fabricating a custom water cooling system for an LS swap, installing a dry-sump oil system, or building a closed-loop transmission cooler circuit, this valve delivers the exact flow control and mounting flexibility required for professional-grade modifications.

Engineered with an -8 AN ORB (O-Ring Boss) inlet and a 1/8-inch secondary port, this drain valve provides dual functionality: the primary AN fitting accepts standard braided hose with -8 AN swage fittings, while the auxiliary 1/8-inch port allows for gauge installation, breather lines, or secondary circuit integration. The ORB design creates a sealed, leak-free connection that withstands pressure cycling typical in performance applications, and the compact 3.54 x 1.02 x 6.3-inch profile fits seamlessly into tight engine bays where every millimeter counts. Weighing just 0.08 pounds, this valve won't contribute to unsprung mass while maintaining the structural integrity required for high-flow applications and repeated thermal cycling.

This universal drain valve is ideal for fabricators building custom cooling systems, off-road enthusiasts upgrading fluid management on lifted trucks, and motorsports competitors integrating auxiliary cooling or secondary fuel systems. It's equally suited for street rod builders, engine swap specialists, and anyone designing bespoke circulation systems where OEM drain points won't accommodate modern plumbing standards. The -8 AN compatibility ensures you can source matched fittings and hose components from any performance automotive supplier, and the 1/8-inch secondary port expands circuit possibilities without requiring additional block-off fittings or adapter clusters.
