#6 Single Feed Holley Black

The #6 Single Feed Holley Black adapter fitting is a precision hydraulic and pneumatic connector engineered for high-pressure fluid transfer systems where reliability and durability are non-negotiable. This straight adapter transitions from 6 AN male ports to 9/16-24 inch male threads, making it an essential component in racing, marine, industrial, and automotive applications that demand secure, leak-free connections. Whether you're building a custom cooling circuit, fuel distribution manifold, or hydraulic control system, this adapter bridges incompatible port types without compromising system integrity.

Manufactured by AEROQUIP using aluminum construction with black anodized finish, the #6 Single Feed Holley Black delivers corrosion resistance and a professional appearance across harsh environments. The anodized aluminum body provides lightweight strength while the straight configuration eliminates bulky elbows, reducing fitting stress and improving flow efficiency in confined spaces. The 6 AN male end accepts standard JIC or AN hose fittings, while the 9/16-24 inch male threads accept industry-standard Holley-pattern ports found on many carburetors, fuel blocks, and custom manifolds. The compact dimensions—2.3 by 1.1 by 3.75 inches—ensure it fits tight packaging layouts without sacrificing accessibility.

Professionals in hot rod fabrication, fuel system tuning, and hydraulic system assembly rely on this adapter to maintain pressure ratings and thread security in high-vibration environments. Installation requires no special tools—hand-tight assembly with appropriate wrenches ensures repeatable, code-compliant connections. It is ideal for custom fuel rails, auxiliary cooling circuits, and pressure-regulated manifold work where Holley-pattern threaded ports are standard. Verify your host port specification before ordering to ensure proper thread engagement and optimal sealing performance.
