It threads into a 7\/16-20 SAE-standard port and caps off a 1\/4-inch OD tube line. The plug is rated to 4500 psi maximum working pressure and handles fluid temperatures from -40 degrees F to 250 degrees F. At 0.8 inches overall length and 0.03 pounds, it is a compact, single-piece fitting used to cap unused ports or dead-end tubing runs during service, repair, or system modification. Licensed plumbers, hydraulic technicians, and fluid-power mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for hydraulic systems, pneumatic lines, fuel systems, and other fluid-power applications where a 37-degree SAE flare port requires sealing. It is commonly used during system commissioning to cap unused branch ports, during repairs to isolate a circuit, or as a permanent seal on a capped-off line. The SAE 070109 standard compliance makes it appropriate for industrial, mobile hydraulic, and HVAC refrigerant-line applications where 37-degree JIC or SAE flare fittings are standard.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e4500 psi maximum working pressure for demanding hydraulic and fluid-power circuits\u003c\/li\u003e\n  \u003cli\u003e37-degree flare angle per SAE 070109 standard\u003c\/li\u003e\n  \u003cli\u003e7\/16-20 SAE thread for secure, leak-resistant seating\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in high-pressure service\u003c\/li\u003e\n  \u003cli\u003eRated from -40 degrees F to 250 degrees F operating temperature range\u003c\/li\u003e\n  \u003cli\u003eCompact at 0.8 inches overall length and 0.03 pounds\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 fluid-power and hydraulic systems using 37-degree SAE flare connections with a 1\/4-inch OD tube and 7\/16-20 thread port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed hydraulic technicians, plumbers, or fluid-power mechanics. Depressurize and fully isolate the system before removing any existing fitting or installing this plug. Use appropriate flare-fitting wrenches to avoid distorting the seating surface. Verify thread engagement and seat contact before returning the system to service pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4500 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\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: SAE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE 070109\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: 900599-4S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51539655295282,"sku":"900599-4S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/66744060f4376f1ddd8d0c903b872c33.jpg?v=1785843907","url":"https:\/\/voomisupply.com\/products\/eaton-900599-4s-steel-flared-tube-plug-1-4-in-od-37-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
