Q/R #5 Str Male Plug w/ Hose Barb Valved Black

The Q/R #5 Str Male Plug w/ Hose Barb Valved Black is a quick-release hydraulic adapter built for high-pressure fluid transfer in performance automotive systems. Designed for mechanics and enthusiasts running custom cooling loops, fuel systems, or pneumatic brake modifications, this straight quick-release connector eliminates the need for manual shutoff valves on both sides of a disconnection. Whether you're building a competition vehicle or upgrading to remote-mounted components, this JIFFY-TITE coupling provides secure, leak-free connections without downtime or fluid loss during service.

This adapter features a 5 AN (5/16-inch) hose barb inlet paired with an integrated quick-release male plug outlet, making it ideal for systems requiring immediate disconnect capability. The valved design incorporates internal check balls that shut off flow the instant you separate the connection, preventing messy spills and pressure loss throughout your system. Constructed from aluminum and finished in black anodize, the housing resists corrosion while maintaining a clean aesthetic in engine bays and custom installations. The FKM seal ensures compatibility with fuel, coolant, and synthetic fluids across a wide temperature range—critical for high-heat or high-boost applications where seal failure means catastrophic fluid loss.

Mechanics frequently specify this coupling for turbo intercooler circuits, fuel rail plenums, and modular radiator setups where frequent system service is part of the build process. The compact footprint (3.6 x 1.65 x 4.85 inches) fits tight engine compartments without sacrificing flow capacity, and the straight body orientation simplifies hose routing in confined spaces. Installation is straightforward: slide your 5 AN hose onto the barb, secure with a crimp ferrule, and thread the opposite end into your system's receiving port. Compatible with any JIFFY-TITE 2000 Series quick-release coupler, this male plug works in pairs for complete disconnect assemblies in custom fuel delivery, coolant bypass, and air suspension applications.
