Both ends feature a 1\/2-inch male adjustable O-ring boss (ORB) configuration with a 3\/4-16 thread on each side, allowing the fitting to be clocked or oriented to a specific angle before locking down. At 1.49 inches in length, this compact union provides a reliable, leak-resistant connection between two hydraulic lines or components. The adjustable design accommodates a range of installation orientations, which reduces the need to route hoses at awkward angles. Licensed hydraulic technicians and fluid power specialists are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe 6403AO8 is suited for mobile hydraulic systems, industrial hydraulic circuits, and fluid power plumbing where two male ORB ports must be joined with directional flexibility. The 6403-NWO series is a recognized SAE O-ring adapter line, and this union fits within that family for steel hydraulic adapter work. It is commonly used in agricultural equipment, construction machinery, and industrial hydraulic panels where reliable, repositionable fittings are required. The 1\/2-inch port size makes it a common choice for medium-flow hydraulic circuits.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMale adjustable O-ring boss on both ends for clocking flexibility during installation\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 thread on both connections per SAE standard\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability in high-pressure hydraulic environments\u003c\/li\u003e\n  \u003cli\u003eCompact 1.49-inch body length for tight installation spaces\u003c\/li\u003e\n  \u003cli\u003ePart of the 6403-NWO series of SAE O-ring adapters\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 systems using 1\/2-inch male adjustable O-ring boss ports with 3\/4-16 threads, consistent with SAE straight thread O-ring boss specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified hydraulic technician or fluid power specialist. Depressurize and fully relieve hydraulic system pressure before disassembling any fittings or lines. Ensure the O-ring is properly seated and lightly lubricated with compatible hydraulic fluid before threading the fitting into place. Do not over-torque; refer to the equipment manufacturer's torque specifications for the applicable port size and thread standard.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Male Adjustable O-Ring Boss\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Male Adjustable O-Ring Boss\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size 1\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size 2\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Length\u003c\/strong\u003e: 1.49 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6403-NWO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCategory\u003c\/strong\u003e: Steel SAE O-Ring Adapters\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403AO8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948468863282,"sku":"6403AO8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4e890f26afc6c44b7eb8c9b52a33da70_6d92c48c-3a05-44c9-bdb5-556caa8e3b07.jpg?v=1791664644","url":"https:\/\/voomisupply.com\/products\/midland-industries-6403ao8-adjustable-o-ring-union-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
