Machined from zinc-plated steel, it threads into 9\/16-18 UN\/UNF-2A ports and is rated for a maximum working pressure of 6,000 psi. The O-ring face seal design minimizes leak paths at the port interface, making it a reliable dead-end plug in high-pressure hydraulic circuits. At 0.03 pounds, it is a compact fitting used to cap unused ports on manifolds, valves, cylinders, and other hydraulic components. Licensed HVAC, plumbing, and hydraulic technicians install this type of plug as part of system commissioning or maintenance.\u003c\/p\u003e\n\u003cp\u003eThis plug is suited for industrial hydraulic and fluid power applications where unused ports must be sealed under high-pressure conditions. Typical install scenarios include capping spare work ports on directional control valves, hydraulic manifold blocks, and cylinder end caps. The straight thread O-ring connection conforms to SAE standard 090109B, making it appropriate for systems built to SAE port specifications. It is used in both stationary industrial equipment and mobile hydraulic applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRated to 6,000 psi maximum working pressure for high-pressure hydraulic service\u003c\/li\u003e\n  \u003cli\u003eMale straight thread O-ring connection type minimizes leak potential at the port face\u003c\/li\u003e\n  \u003cli\u003e9\/16-18 UN\/UNF-2A male thread fits standard SAE straight thread O-ring ports\u003c\/li\u003e\n  \u003cli\u003eZinc-plated steel construction provides corrosion resistance in industrial environments\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch hex socket drive for installation with a standard hex key or allen wrench\u003c\/li\u003e\n  \u003cli\u003eConforms to SAE standard 090109B\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service plug for hydraulic systems with SAE straight thread O-ring ports sized 9\/16-18 UN\/UNF-2A.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or pipefitter. Always depressurize and bleed down the hydraulic system completely before removing or installing any port plug. Use a calibrated torque wrench with the appropriate 1\/4-inch hex bit and follow the equipment manufacturer or SAE torque specification for straight thread O-ring fittings. Inspect the O-ring for damage before installation and replace it if any deformation is present.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Hex Socket Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMale Thread Size\u003c\/strong\u003e: 9\/16-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UN\/UNF-2A\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\u003eMaximum Working Pressure\u003c\/strong\u003e: 6,000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Zinc-Plated Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE 090109B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6 HP5ON-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544597037362,"sku":"6 HP5ON-S","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/448ddbcefbc01f628a3cc44598f4edde.jpg?v=1785930956","url":"https:\/\/voomisupply.com\/products\/parker-6-hp5on-s-hex-socket-plug-9-16-18-male-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
