One end uses a Male Adjustable O-Ring Boss (MAORB) connection, which allows the fitting to be torqued into a fixed orientation during installation. The opposite end uses a standard Male O-Ring Boss (ORB) connection. Both ends are 3\/4-16 UNF thread. Constructed from 316 stainless steel, this union is rated for operating temperatures up to 1000 degrees F, making it suitable for high-heat and corrosive fluid environments. Overall length is 1.644 inches. Licensed plumbers, pipefitters, and hydraulic system technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThe SS6403-08-08 is used in hydraulic lines, fuel systems, and industrial fluid plumbing where two male ORB-ported components must be joined without rotating either component. The MAORB end allows clocking adjustment, so the fitting can be aligned to the correct orientation before the jam nut is tightened. This fitting is part of Midland Industries SS6403-NWO Series, designed for SAE O-ring adapter applications in stainless steel. It is suited for both industrial and marine environments where 316 stainless steel corrosion resistance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for high corrosion resistance in aggressive or marine environments\u003c\/li\u003e\n  \u003cli\u003eMale Adjustable O-Ring Boss end allows positional clocking before final torque\u003c\/li\u003e\n  \u003cli\u003eRated to 1000 degrees F operating temperature for high-heat system applications\u003c\/li\u003e\n  \u003cli\u003eBoth connections are 3\/4-16 UNF thread, 1\/2-inch nominal port size\u003c\/li\u003e\n  \u003cli\u003eCompact at 1.644 inches overall length for tight installation spaces\u003c\/li\u003e\n  \u003cli\u003ePart of the SS6403-NWO Series SAE O-ring stainless adapter line\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for hydraulic and fluid systems using SAE O-ring boss ports with 3\/4-16 UNF thread on both connection points.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed pipefitter, plumber, or qualified hydraulic technician. Depressurize and drain the system fully before removing or installing any fittings. Inspect O-ring seals before assembly and replace if worn or damaged. Tighten the MAORB jam nut only after the fitting is clocked to the desired orientation; do not rely on thread sealant in place of proper O-ring seating.\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 (MAORB)\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 O-Ring Boss (ORB)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 x 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.644 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 1000 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: 316 Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SS6403-NWO\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: SS6403-08-08\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67949699957042,"sku":"SS6403-08-08","price":34.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42af7a9be06aeab1413778f5b09ea8dc_753a1e1b-75cb-4556-813f-567065e619b6.jpg?v=1791698294","url":"https:\/\/voomisupply.com\/products\/midland-industries-ss6403-08-08-adjustable-union-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
