Built for hydraulic and fluid power plumbing, this fitting accommodates a 3\/4 inch tube OD on the flare side and a 3\/4 inch NPT thread on the pipe side. It is rated for a maximum working pressure of 5500 psi and handles temperatures from -40 degrees F to 250 degrees F. The swivel design on the JIC end allows for easier alignment during installation without twisting the connected tube. Manufactured to SAE J514 standards, it suits demanding fluid line applications in industrial, mobile hydraulic, and heavy equipment environments.\u003c\/p\u003e\n\u003cp\u003eThis adapter is used wherever a JIC 37-degree flare tube line must connect to an NPT-threaded port or fitting. Typical applications include hydraulic systems, fluid power assemblies, and high-pressure plumbing on mobile equipment, machine tools, and industrial machinery. The 3\/4 inch sizing makes it a common choice for mid-flow hydraulic circuits. Licensed pipefitters, hydraulic technicians, and fluid power specialists install this fitting in both OEM assembly and field service contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale JIC 37-degree swivel inlet to male NPT outlet — bridges two common thread standards in one body\u003c\/li\u003e\n  \u003cli\u003eRated to 5500 psi maximum working pressure for high-pressure hydraulic service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in hydraulic and fluid power environments\u003c\/li\u003e\n  \u003cli\u003eManufactured to SAE J514 for dimensional and performance compliance\u003c\/li\u003e\n  \u003cli\u003eSwivel end allows rotational alignment without stressing the tube during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for hydraulic and fluid power plumbing systems using 3\/4 inch JIC 37-degree flare tube connections mated to 3\/4 inch NPT-threaded ports, conforming to SAE J514.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or licensed pipefitter. Depressurize and drain the hydraulic circuit fully before removing or installing any fittings. Apply thread sealant only to the NPT male threads — never apply sealant to the JIC flare seating surface, as the metal-to-metal flare cone provides the seal. Torque to the fitting manufacturer or system designer specifications and verify there are no leaks before returning the system to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 5500 psi\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\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.37 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE J514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 2018-12-12S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51542031892786,"sku":"2018-12-12S","price":53.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7e2df03af65a4ffcea2ac15908d9970.jpg?v=1785890209","url":"https:\/\/voomisupply.com\/products\/eaton-2018-12-12s-female-jic-37-to-male-npt-adapter-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
