The 9\/16-18 male ORB end creates a pressure-tight seal against a machined boss seat, while the 3\/8-18 female NPTF end accepts tapered pipe threads for a leak-free mechanical connection. At 1.33 inches in length and rated to 1000 degrees F, this fitting is built for demanding fluid and gas transfer applications where corrosion resistance and high-temperature performance are required. Plumbers, pipefitters, and hydraulic technicians install this adapter to bridge ORB-ported components with standard NPTF-threaded pipe runs.\u003c\/p\u003e\n\u003cp\u003eThis adapter is suited for use in hydraulic systems, industrial fluid lines, and high-temperature process piping where 316 stainless steel is specified for corrosion resistance. The ORB-to-FNPTF configuration is common when connecting pumps, valves, or manifolds with O-Ring Boss ports to threaded pipe assemblies. It is appropriate for both residential and commercial installations requiring a compact, reliable transition fitting in tight spaces or high-vibration environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e316 stainless steel construction for superior corrosion resistance in aggressive media and outdoor environments\u003c\/li\u003e\n  \u003cli\u003e1000 degrees F maximum operating temperature for high-heat process and industrial applications\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch Male O-Ring Boss (9\/16-18 thread) provides a positive, leak-resistant boss-seat seal\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch Female NPTF (3\/8-18 thread) accepts standard tapered pipe threads with mechanical seal\u003c\/li\u003e\n  \u003cli\u003eCompact 1.33-inch body length fits confined plumbing and hydraulic installation spaces\u003c\/li\u003e\n  \u003cli\u003ePart of the SS6405 Series, purpose-built for Male O-Ring to Female NPT transitions\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 systems requiring a 3\/8-inch Male O-Ring Boss to 3\/8-inch Female NPTF adapter in 316 stainless steel construction.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or pipefitters following applicable IPC and IFGC guidelines. Depressurize and drain the system fully before removing or installing any fittings. The Male ORB end relies on an O-ring against a machined boss seat for its seal  -  inspect the seating surface and install a new O-ring if the original shows wear or damage. Apply appropriate thread sealant to the NPTF threads only; do not apply sealant to the ORB seating surface.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Male O-Ring Boss\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread\u003c\/strong\u003e: 9\/16-18 x 3\/8-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.33 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\u003eWeight\u003c\/strong\u003e: 0.1375 pounds\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: SS6405-06-06\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67951653749042,"sku":"SS6405-06-06","price":20.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/96506dc9269be4bd32b3cfa6dca0bbd3_5ed0a1b9-26de-4c50-9b97-ae0b6264ed0d.jpg?v=1791732155","url":"https:\/\/voomisupply.com\/products\/midland-industries-ss6405-06-06-3-8-in-orb-x-fnptf-adapter","provider":"Voomi Supply","version":"1.0","type":"link"}
