This specialized fitting features a 3-inch Figure 602 Female threaded connection (designed to safely receive a standard 3\" 602 male sub and wing nut) on one side, and a standard 4-inch NPT threaded connection on the opposite end.\u003c\/p\u003e\n\u003cp\u003eManufactured from a solid block of high-strength, heat-treated forged alloy steel, this integral swage is built to withstand the mechanical stresses, fluid volumes, and vibration inherent in 6,000 PSI manifold and mud systems. By providing a direct step-up transition from a 3-inch 6,000 PSI flowline to 4-inch threaded components—such as large-bore valves, mud tanks, or rigid piping spools—it eliminates the need for multiple stacked or bushed adapters, thereby reducing potential leak paths and improving overall rig-up safety.\u003c\/p\u003e\n\u003cp\u003eBy utilizing a seamless, integral (one-piece) forged design rather than a fabricated or welded assembly, this swage completely eliminates structural weak points. This ensures superior resistance to pressure surges and provides a reliable connection during demanding cementing, circulating, and fluid transfer operations.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eFeatures \u0026amp; Benefits\u003c\/b\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eIntegral Forged Construction:\u003c\/b\u003e Machined from a single block of premium alloy steel, eliminating weld seams and providing maximum structural integrity under pressure surges and vibrations.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eFemale Threaded Connection:\u003c\/b\u003e Features a precision-machined 3\" 602 female thread, ready to securely accept any standard 3\" 602 male wing nut assembly for rapid field integration.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eExpanded Pipe Transition:\u003c\/b\u003e Safely adapts a 3\" hammer union connection up to a larger 4\" NPT connection, ideal for routing fluids into larger-capacity secondary manifold lines, mud lines, or processing equipment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003eHigh-Pressure Durability:\u003c\/b\u003e The 3\" Fig 602 female end is engineered for standard 6,000 PSI Cold Working Pressure (CWP) environments. \u003ci\u003e(Note: System pressure must be strictly regulated to the maximum rating of the 4\" NPT threaded connection).\u003c\/i\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003e\u003cb\u003ePrecision Machined Threads:\u003c\/b\u003e The 4\" NPT threads are cut to exacting API tolerances to ensure fast makeup, galling resistance, and a reliable leak-proof seal.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cb\u003eSpecifications \u0026amp; Technical Details\u003c\/b\u003e\u003c\/p\u003e\n\u003ctable style=\"width: 100.036%; height: 197px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 19.6px;\"\u003e\u003cstrong\u003eCategory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 19.6px;\"\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 19.6px;\"\u003e\u003cspan\u003e\u003cb\u003eComponent Type\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 19.6px;\"\u003e\u003cspan\u003eSwage \/ Crossover Adapter\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 39.2px;\"\u003e\u003cspan\u003e\u003cb\u003ePrimary Connection (End 1)\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 39.2px;\"\u003e\u003cspan\u003e3\" Fig 602 Female (Threaded)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 39.2px;\"\u003e\u003cspan\u003e\u003cb\u003eSecondary Connection (End 2)\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 39.2px;\"\u003e\u003cspan\u003e4\" NPT (National Pipe Thread)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20.6px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 20.6px;\"\u003e\u003cspan\u003e\u003cb\u003eMaterial Construction\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 20.6px;\"\u003e\u003cspan\u003eHigh-Strength Forged Alloy Steel\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 39.2px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 39.2px;\"\u003e\u003cspan\u003e\u003cb\u003ePressure Rating\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 39.2px;\"\u003e\u003cspan\u003eUp to 6,000 PSI CWP on 602 end (Derated by NPT Thread limitations)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.6px;\"\u003e\n\u003ctd style=\"width: 31.9228%; height: 19.6px;\"\u003e\u003cspan\u003e\u003cb\u003eService Application\u003c\/b\u003e\u003c\/span\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 65.6171%; height: 19.6px;\"\u003e\u003cspan\u003eStandard Service (Sour Service H2S available upon request)\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cb\u003eApplications\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThis 3\" Female x 4\" NPT Crossover Swage is a critical utility fitting for medium-to-high pressure oilfield manifolds.
