It features a 37-degree flare seat on the tube end and a male NPT threaded end on the opposite side, providing a reliable metal-to-metal seal. The connector accommodates a 1\/2-inch tube OD with a 0.28-inch inside diameter and measures 1.53 inches in overall length. Rated to 6000 psi maximum working pressure, it is built for demanding hydraulic and instrumentation applications where leak-free connections are critical. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers.\u003c\/p\u003e\u003cp\u003eThis connector is suited for residential and commercial hydraulic lines, instrumentation tubing, and fluid power systems operating across a wide temperature range of -40 to 250 degrees F. It is commonly installed where a tubing run must terminate at a threaded port on a valve, manifold, pump, or cylinder. The SAE J514 (SAE 070102) standard compliance makes it appropriate for mobile equipment, industrial machinery, and process piping applications requiring a secure flare-to-pipe transition.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare seat provides a positive metal-to-metal seal without additional sealant on the flare\u003c\/li\u003e\n\u003cli\u003e6000 psi maximum working pressure rated for high-pressure hydraulic service\u003c\/li\u003e\n\u003cli\u003eFlare x MNPT end configuration transitions tubing to NPT-threaded ports\u003c\/li\u003e\n\u003cli\u003eWide service temperature range from -40 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eSAE 070102 standard compliance for verified dimensional and performance consistency\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in demanding industrial and fluid power environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for hydraulic and instrumentation tubing systems using 1\/2-inch OD tubing with a 37-degree flare and 1\/4-inch NPT threaded port connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed pipefitter, plumber, or qualified hydraulic technician following applicable codes such as the IPC or relevant SAE standards. Depressurize and isolate the hydraulic or fluid system completely before removing or installing any fittings. Inspect the tubing flare for concentricity and surface defects before assembly, as an imperfect flare is the leading cause of joint leakage. Do not overtighten; follow torque guidelines published in SAE J514 for the applicable tube size and material.\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\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.28 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.53 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6000 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\u003eStandard\u003c\/strong\u003e: SAE 070102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: 2021-4-8S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51540801225010,"sku":"2021-4-8S","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/da1e34dc72230f406b3bfb4937a3e66e.jpg?v=1785864148","url":"https:\/\/voomisupply.com\/products\/eaton-2021-4-8s-steel-flared-tube-connector-1-2-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
