It accepts a 3\/4 inch tube OD on the male end and a 5\/8 inch tube OD on the female end, with a 7\/8-14 UNF thread and a reduced thread size of 1-1\/16-14. Constructed from brass, this fitting handles working pressures up to 650 psi and temperatures up to 250 degrees F, making it well-suited for refrigerant lines and hydraulic circuits in demanding trade applications. Licensed HVAC technicians and plumbers are the typical installers.\u003c\/p\u003e\u003cp\u003eThis fitting is used in residential and light commercial HVAC systems, refrigeration equipment, and fluid lines where a flare-to-flare transition between two different tube sizes is needed. The 45-degree flare profile conforms to SAE J512 and SAE J513 standards, and the fitting carries a UL Listing, making it appropriate for installations governed by those requirements. Its compact overall length of 1.86 inches suits tight equipment bays and panel installations where clearance is limited.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance in refrigerant and fluid service\u003c\/li\u003e\n\u003cli\u003e45-degree flare angle compliant with SAE J512 and SAE J513\u003c\/li\u003e\n\u003cli\u003eMale flare to female flare end connections for inline tube-size reduction\u003c\/li\u003e\n\u003cli\u003eRated to 650 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eUL Listed for use in code-compliant installations\u003c\/li\u003e\n\u003cli\u003eCompact 1.86 inch overall length for space-restricted installs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style flare fitting for HVAC, refrigeration, and fluid-handling systems using 45-degree SAE flare connections with 3\/4 inch and 5\/8 inch tube OD lines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber. Shut off and recover all refrigerant or depressurize the fluid system completely before disconnecting or connecting any flare fitting. Use a calibrated flaring tool to produce clean, properly seated 45-degree flares on both tube ends before tightening to prevent leaks. Avoid over-tightening, which can crack brass flare seats; tighten by hand first, then snug with a flare wrench.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD (Male x Female)\u003c\/strong\u003e: 3\/4 x 5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/8-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Thread Size\u003c\/strong\u003e: 1-1\/16-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 650 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: 1.86 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.26 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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-12-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540180828466,"sku":"661FHD-12-10","price":40.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/383c8d90d836913c1c73d8a961d59ceb.jpg?v=1785848207","url":"https:\/\/voomisupply.com\/products\/parker-661fhd-12-10-brass-male-to-female-flare-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
