Q/R Male 1/4in NPT Plug Black

The Q/R Male 1/4in NPT Plug Black by JIFFY-TITE is a quick-release hydraulic coupling component engineered for tactical equipment, medical evacuation systems, and field-deployable fluid transfer applications. Designed for law enforcement and military personnel who demand reliability under austere conditions, this compact male plug enables rapid connection and disconnection of pressurized fluid lines without spillage or system contamination. The 1/4-inch NPT (National Pipe Thread) interface is the industry standard for mobile tactical platforms, including medical rigs, hydraulic tool systems, and portable decontamination units.

Built from hardened steel with a durable black oxide finish, the Q/R Male 1/4in NPT Plug resists corrosion and maintains dimensional accuracy across repeated use cycles in salt spray and high-humidity environments. The quick-release design incorporates a spring-loaded poppet mechanism that prevents fluid loss during disconnection and automatically seals the line when uncoupled—critical for field operations where fluid loss equals lost capability. The 1/4-inch NPT male thread specification ensures compatibility with standard ISO 7241-A quick-coupling receptacles, the global benchmark for tactical hydraulic systems used by NATO-aligned forces.

Operators benefit most from this plug in modular medical kits, rapid-deployment hydraulic rescue tools, and vehicle-mounted fluid systems where connection speed directly impacts mission tempo. Installation is straightforward: simply hand-tighten the male plug into any ISO 7241-A quick-coupler receptacle until the poppet seals, then couple via the quick-release sleeve mechanism. At 0.1 lbs with compact 3.65 x 1.65 x 4.9-inch dimensions, the plug adds minimal weight to load-bearing systems while delivering maximum reliability in high-pressure applications up to standard working pressures.
