It accepts a 0.5 inch tube outer diameter and threads onto fittings with a 3\/4-16 SAE thread. The 37-degree flare angle conforms to SAE standards, creating a leak-resistant metal-to-metal seal under pressure. Rated to 4000 psi maximum working pressure, this nut suits demanding service environments where a secure, reusable tube connection is required. Licensed plumbers, hydraulic technicians, and fluid-power mechanics install these nuts as part of flared-tube fitting assemblies on hydraulic lines, fuel systems, and pneumatic circuits.\u003c\/p\u003e\n\u003cp\u003eThis tube nut is suited for 37-degree JIC-style flare applications in industrial, mobile-equipment, and fluid-power systems. It is used wherever a 0.5 inch OD tube must be coupled to a 3\/4-16 SAE-threaded fitting body. Typical installations include hydraulic return and pressure lines, fuel delivery plumbing, and lubrication circuits that require a reusable, metal-bodied connection. The SAE 070110 standard governs dimensional and performance requirements for this fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e37-degree flare angle per SAE 070110 standard for leak-resistant metal-to-metal sealing\u003c\/li\u003e\n  \u003cli\u003e4000 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 SAE thread size for compatibility with standard JIC-style fitting bodies\u003c\/li\u003e\n  \u003cli\u003eSteel construction for strength and durability in hydraulic and fuel-line service\u003c\/li\u003e\n  \u003cli\u003e0.84 inch overall length suits compact tube-end assemblies\u003c\/li\u003e\n  \u003cli\u003eThree-piece assembly design allows tube preparation and installation without cutting the nut free\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 37-degree flare tube assemblies using 0.5 inch OD tubing with 3\/4-16 SAE-threaded fitting bodies conforming to SAE 070110.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHydraulic technicians and pipefitters install this tube nut as part of a flared-tube assembly. Depressurize and drain the hydraulic or fluid circuit completely before disassembling any tube connections. Inspect the tube flare for cracks or deformation before assembling the nut; a damaged flare face will not seal reliably. Tighten to the fitting-body manufacturer's specified procedure using a calibrated flare-fitting wrench; do not over-torque, as this can crack the flare or distort the nut seat.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.84 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 070110\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: 1290-8S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51539046760754,"sku":"1290-8S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fd2ba77740111b026ba1673629399777.jpg?v=1785833735","url":"https:\/\/voomisupply.com\/products\/eaton-1290-8s-steel-flared-tube-nut-1-2-in-od-3-4-16-sae","provider":"Voomi Supply","version":"1.0","type":"link"}
