It transitions between 1\/2 inch and 5\/8 inch tube outside diameters using a 45-degree flare angle and a 7\/8-14 UNF thread on the male end, with a reduced thread size of 3\/4-16 on the female end. Constructed entirely from brass, this fitting handles working pressures up to 750 psi and temperatures up to 250 degrees F. It is sold individually and is a standard catalog component for licensed HVAC and refrigeration technicians.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial HVAC systems, refrigeration lines, and other fluid or gas circuits where SAE-standard flare connections are required. The 45-degree flare geometry conforms to SAE J512 and SAE J513 standards. The reduced thread on the female end accommodates the step-down between the two tube sizes, making it appropriate for applications where line sizes change at a junction point. Installation is performed by HVAC technicians and refrigeration mechanics working with copper or compatible tubing systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree flare angle per SAE J512 and SAE J513\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in refrigerant and fluid service\u003c\/li\u003e\n\u003cli\u003eHandles up to 750 psi working pressure\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F (121 degrees C) maximum working temperature\u003c\/li\u003e\n\u003cli\u003eMale end: 7\/8-14 UNF thread; female end: 3\/4-16 reduced thread\u003c\/li\u003e\n\u003cli\u003eUL Listed; meets SAE J512, SAE J513 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with 1\/2 inch and 5\/8 inch OD tubing in SAE 45-degree flare systems conforming to SAE J512 and SAE J513 specifications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or refrigeration mechanic. Depressurize and recover any refrigerant from the system before disconnecting or installing flare fittings. Use a calibrated flaring tool to form consistent 45-degree flares on the tubing ends before making up the connection. Do not overtighten; refer to applicable SAE and system manufacturer guidance for proper assembly practices.\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 Outside Diameter\u003c\/strong\u003e: 1\/2 inch x 5\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size (Male)\u003c\/strong\u003e: 7\/8-14 UNF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReduced Thread Size (Female)\u003c\/strong\u003e: 3\/4-16\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: 750 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: 1.67 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 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-8-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538610389298,"sku":"661FHD-8-10","price":30.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3f2568176e1c72e86f90a2fe58869a56.jpg?v=1785825316","url":"https:\/\/voomisupply.com\/products\/parker-661fhd-8-10-brass-male-to-female-flare-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
