Q/R #6 Male O-Ring Boss Plug Valved Black

The Q/R #6 Male O-Ring Boss Plug Valved Black is a quick-release adapter designed for hydraulic and pneumatic systems requiring secure, leak-free connections. Manufactured by JIFFY-TITE, this component serves technicians, mechanics, and industrial professionals who need reliable disconnect capability without fluid loss. The valved design prevents spillage during coupling and uncoupling, making it essential for maintenance work, equipment servicing, and applications where fluid containment is critical to safety and cleanliness.

This adapter features a 6 AN male O-ring boss connection on one side that mates with industry-standard quick-release couplings. The black anodized aluminum construction provides corrosion resistance and durability in demanding environments, while the FKM elastomer seal ensures compatibility with a wide range of hydraulic fluids, oils, and coolants. The internal valve mechanism automatically closes when disconnected, containing residual pressure and preventing environmental contamination—a critical feature for systems operating at up to 2000 PSI. The straight configuration allows direct flow without bends, minimizing pressure loss and turbulence in high-performance circuits.

This plug adapter is ideal for mobile equipment, test benches, and fluid-transfer stations where frequent disconnects are routine. Compact at 3.65 inches in length and weighing only 0.07 lbs, it integrates easily into tight spaces without adding bulk. Installation requires only standard wrench tools; the O-ring boss connection ensures a metal-to-metal seal when properly torqued, eliminating the need for thread sealant tape. Compatible with the JIFFY-TITE 2000 Series quick-release system and any adapter featuring a matching female quick-release interface, this component delivers consistent performance across agricultural, manufacturing, aerospace, and automotive applications.
