It accepts 1\/2-inch OD tubing on both ends using a 45-degree SAE flare seat and a 3\/4-16 UNF thread. Rated to 750 psi maximum working pressure and 250 degrees F, this fitting is built for refrigeration, HVAC, and hydraulic tubing systems where a secure, leak-free union is required. Licensed HVAC technicians and refrigeration mechanics are the primary installers. The overall installed length is 1.43 inches, keeping the assembly compact in tight routing situations.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial HVAC systems, refrigeration lines, and hydraulic tubing assemblies wherever two female flared tube ends must be coupled inline. The 45-degree flare geometry conforms to SAE J512 and SAE J513 standards, making it appropriate for refrigerant line sets, fuel lines, and other tubing circuits that require a rated pressure-bearing union. It carries a UL Listing and suits applications where code-compliant fittings are specified.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eFemale-to-female flare union joins two 1\/2-inch OD flared tube ends inline\u003c\/li\u003e\n  \u003cli\u003e45-degree SAE flare seat per SAE J512 and SAE J513\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF thread on both ends for secure engagement\u003c\/li\u003e\n  \u003cli\u003e750 psi maximum working pressure for demanding fluid and refrigerant circuits\u003c\/li\u003e\n  \u003cli\u003e250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eUL Listed construction; complies with SAE J512, SAE J513\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 1.43 inches suits tight tubing layouts\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 HVAC, refrigeration, and hydraulic tubing systems using 1\/2-inch OD tubing with a 45-degree SAE flare and 3\/4-16 UNF thread connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified mechanic. Depressurize and recover any refrigerant or fluid from the system before disassembling existing fittings. Hand-tighten the flare nuts first to seat the flare cone squarely, then torque with a flare nut wrench to avoid distorting the flare. Verify the system holds pressure before returning it to service.\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\u003eTube OD\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare (Female to Female)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlare Angle\u003c\/strong\u003e: 45 degrees\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: 1.43 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: 660FHD-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540454474034,"sku":"660FHD-8","price":26.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b059073b03fe7c6cfe50e6bc396d4d1d.jpg?v=1785855697","url":"https:\/\/voomisupply.com\/products\/parker-660fhd-8-brass-flared-tube-union-1-2-in-female-to-female","provider":"Voomi Supply","version":"1.0","type":"link"}
