Built from steel with a 3\/4-inch hose size and a 1-1\/16-12 thread size, this coupler carries a maximum working pressure of 4,000 psi and a maximum flow rate of 28.00 GPM. The straight body profile measures 3.35 inches in overall length. It conforms to ISO 7241-1 Series A standards and belongs to the Parker 6600 Series. Licensed HVAC and fluid power technicians, hydraulic mechanics, and equipment service professionals install this fitting in mobile and industrial hydraulic circuits.\u003c\/p\u003e\n\u003cp\u003eThis coupler is rated for use in mobile hydraulic applications, including snow plows and truck and trailer connections. The female ORB configuration seals against a machined boss port using an O-ring face seal, reducing leak paths compared to pipe thread fittings. Its steel construction and SAE shaft type make it suitable for demanding field service environments where vibration and pressure cycling are common. The 4,000 psi pressure rating supports high-demand circuits typical in commercial vehicle and mobile equipment hydraulics.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale O-Ring Boss (ORB) coupler with straight body and threaded connection\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 4,000 psi for high-pressure hydraulic circuits\u003c\/li\u003e\n  \u003cli\u003eMaximum flow rate of 28.00 GPM\u003c\/li\u003e\n  \u003cli\u003e3\/4-inch hose size with 1-1\/16-12 thread size\u003c\/li\u003e\n  \u003cli\u003eConforms to ISO 7241-1 Series A standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction suited for mobile and heavy-duty applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eRated for use with mobile hydraulic applications including snow plows and truck and trailer connections.
