It transitions between a 3\/8-inch OD tube on the male end and a 1\/2-inch OD tube on the female end, with a primary thread size of 3\/4-16 UNF and a reduced thread size of 5\/8-18. Rated to 1000 psi maximum working pressure and 250 degrees F, this fitting handles the demands of typical refrigerant and fuel-gas line work. HVAC technicians and refrigeration mechanics install this part when connecting or adapting flared tubing runs of different sizes.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial HVAC, refrigeration, and plumbing applications where SAE 45-degree flare connections are the specified joint type. It is suited for use in refrigerant lines, fuel-gas tubing, and hydraulic lines that fall within its pressure and temperature ratings. The flare-by-flare end configuration allows it to serve as a union-style adapter between two flared tube ends of differing outside diameters without requiring soldering or brazing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree SAE flare angle on both ends, conforming to SAE J512 and SAE J513 standards\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and reliable sealing in refrigerant and fuel-gas service\u003c\/li\u003e\n  \u003cli\u003eReduces from 3\/4-16 UNF (3\/8-inch OD tube) male flare to 5\/8-18 UNF (1\/2-inch OD tube) female flare\u003c\/li\u003e\n  \u003cli\u003eRated to 1000 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003eUL Listed; meets SAE J512 and SAE J513 standards\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 systems using SAE 45-degree flare tube connections with 3\/8-inch and 1\/2-inch OD tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is installed by licensed HVAC technicians or refrigeration mechanics. Always recover refrigerant and de-pressurize the system before disconnecting or installing flare fittings. Use a calibrated flare tool to ensure proper flare geometry before tightening; an improperly formed flare is the most common cause of joint leaks. Do not over-tighten brass flare fittings, as this can crack the flare seat; follow the torque guidance in SAE J512 for the applicable tube size.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 3\/8 x 1\/2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReduced Thread Size\u003c\/strong\u003e: 5\/8-18 UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1000 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 661FHD-6-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541482570034,"sku":"661FHD-6-8","price":26.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6d09dabd87eff9e986b51f5f7d18d44c.jpg?v=1785877412","url":"https:\/\/voomisupply.com\/products\/parker-661fhd-6-8-brass-male-to-female-flare-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
