It threads into a 3\/4-16 SAE port and accepts a 1\/2-inch tube OD, providing a secure, leak-resistant closure on open flare fittings during service, testing, or system reconfiguration. The plug has an overall length of 0.94 inches and weighs 0.11 pounds. Rated to 4000 psi maximum working pressure, it handles operating temperatures from -40 degrees F to 250 degrees F. This fitting meets SAE standard 070109 and is suited for use by hydraulic technicians, plumbers, and fluid-power service professionals.\u003c\/p\u003e\u003cp\u003eThis plug is used in hydraulic lines, pneumatic circuits, and fluid-transfer systems wherever a flare-end port needs to be blanked off cleanly. Common applications include capping unused ports during system testing, isolating a leg of a hydraulic circuit for maintenance, or plugging tube ends during equipment storage. The 37-degree flare geometry is the standard JIC\/SAE flare configuration found widely in industrial, mobile hydraulic, and HVAC refrigerant-line work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree SAE flare end connection for leak-resistant port sealing\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 4000 psi for demanding hydraulic applications\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e3\/4-16 SAE thread size for direct engagement with standard JIC ports\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in high-pressure fluid systems\u003c\/li\u003e\n\u003cli\u003eMeets SAE 070109 standard\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement plug for hydraulic and fluid-system applications using 37-degree flare fittings with a 1\/2-inch tube OD and 3\/4-16 SAE thread ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or plumber. Depressurize and isolate the affected circuit completely before removing or installing any fitting. Use the appropriate flare-nut wrench to avoid rounding the fitting; do not use pipe wrenches on flare fittings. Verify thread engagement and inspect the flare seating surface for damage before torquing to avoid leaks.\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: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/2 inch\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\u003eOverall Length\u003c\/strong\u003e: 0.94 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4000 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: 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE 070109\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: 900599-8S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51541145256242,"sku":"900599-8S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f5e65e1f3a9fe36f93469c53bf3c29fa.jpg?v=1785868947","url":"https:\/\/voomisupply.com\/products\/eaton-900599-8s-steel-flared-tube-plug-1-2-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
