It provides a reliable, leak-resistant seal by compressing an O-ring against a machined seat rather than relying on thread interference alone. The plug accepts a 1\/4 inch male straight thread and is rated for a maximum working pressure of 4500 psi with a burst pressure rating of 6000 psi. It is sized and configured for applications where a port or line must be capped off cleanly without introducing leak paths. Licensed plumbers, pipefitters, and hydraulic system technicians working on industrial or mobile hydraulic circuits are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis hex plug is suited for industrial hydraulic systems, fluid power circuits, and high-pressure plumbing where straight thread O-ring port connections are specified. The straight thread O-ring design meets SAE standard 090109A, making it appropriate for OEM equipment builds, maintenance replacement, and hydraulic circuit modifications in both stationary and mobile applications. It is rated for service across a wide temperature range, from -40 degrees F to 250 degrees F, covering most industrial and mobile hydraulic operating environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch male straight thread O-ring connection for leak-resistant port sealing\u003c\/li\u003e\n  \u003cli\u003eMaximum working pressure of 4500 psi for demanding hydraulic service\u003c\/li\u003e\n  \u003cli\u003ePressure rating of 6000 psi\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eHex drive configuration allows installation and removal with standard wrenches\u003c\/li\u003e\n  \u003cli\u003eMeets SAE 090109A standard\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 industrial fluid power systems utilizing 1\/4 inch male straight thread O-ring ports conforming to SAE 090109A.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified hydraulic technicians or licensed pipefitters. Depressurize and isolate the hydraulic circuit fully before removing or installing any fittings. Use an appropriately sized hex wrench or socket to seat the fitting without overtightening, which can damage the O-ring and compromise the seal. Inspect the O-ring for nicks or displacement before pressurizing the system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male Straight Thread O-Ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 4500 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 6000 psi\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\u003eMinimum Working Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandard\u003c\/strong\u003e: SAE 090109A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 900598-4S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51541255881010,"sku":"900598-4S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b3087149e679561a3b26fb4028f019b.jpg?v=1785870902","url":"https:\/\/voomisupply.com\/products\/eaton-900598-4s-hex-plug-1-4-in-male-thread-o-ring-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
