Q/R Plug #8 Push Lock Hose End- Valved

The Q/R Plug #8 Push Lock Hose End with valved design is a quick-disconnect coupling essential for any serious enthusiast managing high-pressure fluid systems in performance vehicles, hydraulic brake conversions, or custom cooling loops. This straight-body adapter bridges 8 AN hose barbs to push-lock plugs, eliminating the need to break hard lines or suffer fluid loss during system maintenance. Built by JIFFY-TITE, a trusted name in automotive fluid transfer components, this coupling serves mechanics and fabricators who demand leak-free connections without the downtime of traditional threaded fittings.

The valved feature is critical in performance applications—internal check balls prevent backflow and fluid spillage when you disconnect under pressure, a game-changer when working on charged fuel systems or pressurized cooling circuits. The aluminum body is black anodized for corrosion resistance in engine bays, while the FKM elastomer seal handles both high-temperature and synthetic fluid compatibility. The push-lock design engages via a simple straight hose barb and requires no tools to couple or uncoupled; you simply push the female connector onto the male barb until it locks, then depress the collar to release. This 3000 Series rating ensures reliable operation in demanding street and track environments where fluid integrity directly impacts safety and reliability.

Ideal for brake system upgrades, fuel injection tuning kits, hydraulic clutch conversions, and custom radiator plumbing, the Q/R Plug #8 Push Lock Hose End eliminates spills during component swaps and testing cycles. The 8 AN barb size (which accommodates -8 hose, roughly 1/2-inch ID) is the sweet spot for mid-range hydraulic and fuel circuits in street performance builds. Installation is straightforward—slide the hose onto the barb with a slight twisting motion until the hose shoulder seats fully, then use a hose clamp if additional security is desired. Weighing just 0.11 lbs and measuring 3.6 x 1.65 x 5.05 inches, it fits tight quarters and doesn't add measurable mass to your system.
