The plug measures 0.767 inches in length with a 9\/16-inch hex drive and a 1-1\/16-12 thread specification. Its 316 stainless steel construction delivers strong resistance to corrosion and elevated temperatures, making it suitable for demanding fluid system environments. Licensed plumbers, pipe fitters, and hydraulic technicians install this fitting during system maintenance or port sealing operations.\u003c\/p\u003e\u003cp\u003eThis plug is used in hydraulic, pneumatic, and fluid transfer systems where SAE O-Ring Boss ports require capping. It fits residential and commercial applications including industrial equipment, fluid power systems, and high-temperature plumbing assemblies. The hollow hex design allows installation and removal with a standard hex key. With an operating rating of 1000 degrees F, this plug is suited for systems that see high thermal cycling or elevated process temperatures.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e316 stainless steel construction for corrosion resistance in harsh fluid environments\u003c\/li\u003e\n\u003cli\u003e3\/4-inch male O-Ring Boss connection for reliable leak-free port sealing\u003c\/li\u003e\n\u003cli\u003e1-1\/16-12 thread specification for precise SAE ORB fitment\u003c\/li\u003e\n\u003cli\u003eRated to 1000 degrees F operating temperature\u003c\/li\u003e\n\u003cli\u003eCompact 0.767-inch length with 9\/16-inch hollow hex drive for easy installation and removal\u003c\/li\u003e\n\u003cli\u003ePart of the SS6408-HHP Series SAE O-Ring Hollow Hex Plug line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement fitting for SAE O-Ring Boss port applications in hydraulic, pneumatic, and fluid power systems requiring a 3\/4-inch male ORB plug.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed plumbers, pipe fitters, or hydraulic technicians familiar with SAE O-Ring Boss fittings. Depressurize and drain the system fully before removing or installing any port plug. Use a calibrated hex key sized for 9\/16-inch drive and do not over-torque, as damage to the O-ring seat will cause leaks. Follow applicable system manufacturer specifications and relevant fluid power or piping codes when servicing pressurized lines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Male O-Ring Boss (SAE ORB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Specification\u003c\/strong\u003e: 1-1\/16-12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 9\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.767 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperating 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\u003eWeight\u003c\/strong\u003e: 0.169 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: SS6408-HH-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948346212658,"sku":"SS6408-HH-12","price":19.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f41563666f2c4a1788b4f2171c7a0532.jpg?v=1791662580","url":"https:\/\/voomisupply.com\/products\/midland-industries-ss6408-hh-12-hollow-hex-plug-3-4-in-orb","provider":"Voomi Supply","version":"1.0","type":"link"}
