It uses a male straight thread O-ring connection to seal against a mating port face, eliminating reliance on thread deformation alone. Manufactured from zinc-plated steel, the plug carries a maximum working pressure rating of 6000 psi. The 5\/16-inch hex drive and 5\/8-inch overall length make it a compact, low-profile solution. This plug is installed by hydraulic technicians and mechanical tradespeople working on high-pressure fluid circuits, manifolds, and port blocks.\u003c\/p\u003e\u003cp\u003eThis plug is suited for closing unused ports on hydraulic cylinders, valves, manifolds, and fluid power components in industrial and mobile equipment. The male straight thread O-ring configuration conforms to SAE standard 090109B and the UN\/UNF-2A thread standard, making it a common choice for port plugging on equipment that demands a pressure-rated, vibration-resistant seal. It is appropriate for use in both stationary industrial machinery and mobile hydraulic systems where port integrity is critical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e6000 psi maximum working pressure for high-pressure hydraulic circuits\u003c\/li\u003e\n\u003cli\u003eMale straight thread O-ring connection provides a positive face seal at the port\u003c\/li\u003e\n\u003cli\u003eZinc-plated steel construction offers corrosion resistance in industrial environments\u003c\/li\u003e\n\u003cli\u003eCompact 5\/8-inch overall length minimizes protrusion from the port face\u003c\/li\u003e\n\u003cli\u003e5\/16-inch hex socket drive for installation with standard hex keys\u003c\/li\u003e\n\u003cli\u003eConforms to SAE 090109B and UN\/UNF-2A thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service plug for hydraulic and fluid power components using 3\/4-16 male straight thread O-ring ports conforming to SAE 090109B specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal should be performed by a qualified hydraulic technician or mechanic. Depressurize the hydraulic circuit completely and relieve all stored pressure before removing or installing any port plug. Use the correct 5\/16-inch hex key to avoid rounding the socket drive. Inspect and replace the O-ring if it shows any sign of damage, flattening, or degradation before re-installing the plug.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 3\/4-16\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: 6000 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5\/8 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: 0.06 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40175305\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 8 HP5ON-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543018209586,"sku":"8 HP5ON-S","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d067b46316d77f78b237abd079ff3ad.jpg?v=1785913757","url":"https:\/\/voomisupply.com\/products\/parker-8-hp5on-s-hex-socket-plug-3-4-16-o-ring-6000-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
