Q/R #4 Male Plug Valved Black

The Q/R #4 Male Plug Valved Black is a professional-grade quick-release coupling adapter engineered for high-pressure fluid transfer systems in hydraulic and pneumatic applications. Designed by JIFFY-TITE, this straight 4 AN male quick-release plug delivers dependable performance for technicians, mechanics, and industrial operators who demand fast, leak-free connections. Whether servicing hydraulic lines on heavy equipment, aircraft systems, or mobile platforms, this adapter eliminates downtime while maintaining system integrity under demanding operational conditions.

Built from lightweight aluminum with black anodized finish, the Q/R #4 Male Plug Valved Black combines durability against corrosion with minimal weight addition to assemblies. The integrated valved design prevents fluid spillage and atmospheric contamination when disconnected, a critical safety feature in closed-loop hydraulic and pneumatic circuits. FKM (fluorocarbon) seals ensure reliable performance across temperature extremes and chemical compatibility with standard industrial fluids, while the straight body orientation allows installation in confined spaces where angled adapters cannot fit. The 2000 Series construction rating provides confidence in high-pressure applications up to system specifications.

Maintenance technicians and field operators benefit from the quick-connect/disconnect convenience during equipment servicing, reducing labor time and fluid waste. This male plug adapter mates seamlessly with compatible quick-release female sockets in standard AN configurations, making it ideal for replacement, upgrade, or new-build hydraulic system projects. Installation requires no special tools—simply align and push to engage the internal ball-lock mechanism. Its compact footprint (3.6 x 1.65 x 4.85 inches) and lightweight design (0.07 lbs) make it suitable for mobile equipment, aerospace systems, and stationary industrial setups where reliability and repeatability are non-negotiable.
