It features a 37-degree flare seat on the tube end and a male NPT thread on the opposite end, creating a Flare x MNPT configuration. With a maximum working pressure of 5500 psi and a temperature range of -40 to 250 degrees F, this connector handles demanding service conditions. The 3\/4 inch tube OD and 1\/2 inch NPT thread sizes make it a common fitting in industrial, mobile equipment, and fluid power plumbing systems. Licensed plumbers, pipefitters, and hydraulic technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis connector is suited for use in hydraulic lines, fuel systems, and other high-pressure fluid circuits where a 37-degree flare-to-NPT transition is required. The Flare x MNPT end configuration allows direct connection between a flared tube and a female NPT port on a valve, manifold, pump, or cylinder. It is commonly found in industrial machinery, agricultural equipment, and mobile hydraulic applications requiring a reliable, leak-resistant joint at elevated pressures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare seat meets SAE J514 flare fitting standards (SAE 070102)\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 5500 psi for high-demand hydraulic service\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eFlare x MNPT end connection for tube-to-pipe-thread transitions\u003c\/li\u003e\n\u003cli\u003eSteel construction for strength and durability in pressurized systems\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.06 inches (52.30 mm) for compact installation clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for hydraulic and fluid power systems requiring a 3\/4 inch OD flared tube connection to a 1\/2 inch NPT female port.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, hydraulic technician, or licensed plumber. Depressurize and drain the system fully before removing or installing any fittings. Torque the NPT end using appropriate pipe wrenches and apply thread sealant compatible with the system fluid. Inspect the flare seat and tube flare for damage before assembly to ensure a leak-free joint.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5500 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 070102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2021-8-12S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51543012606258,"sku":"2021-8-12S","price":20.3,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/61a50b5c1133b5ac6b7f97ef14b05a6e.jpg?v=1785913661","url":"https:\/\/voomisupply.com\/products\/eaton-2021-8-12s-steel-flared-tube-connector-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
