It accepts 3\/4-inch outside diameter tubing on the flare end and threads to a 1-1\/16-14 UNF swivel nut on the mating end. The 45-degree flare angle seals against the tube seat per SAE J512 and SAE J513 standards. Rated to 550 psi maximum working pressure and 250 degrees F, this fitting is suited for refrigerant, hydraulic, and fuel line applications where a rigid elbow would create assembly or routing constraints. Licensed HVAC technicians and plumbers are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and commercial applications involving flared copper or aluminum tubing. Common install scenarios include refrigeration line sets, air conditioning systems, and hydraulic circuits where a 90-degree directional change is needed without using a brazed or compression connection. The swivel nut design allows the nut to rotate freely during assembly, reducing the chance of twisting or kinking the tubing during tightening. It carries a UL Listing and meets SAE J512 and SAE J513, making it appropriate for regulated mechanical and refrigeration systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree swivel nut elbow with 45-degree flare seating angle per SAE J512 and SAE J513\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and compatibility with refrigerant and hydraulic media\u003c\/li\u003e\n  \u003cli\u003eSwivel end allows free rotation during assembly, preventing tube twist and kink\u003c\/li\u003e\n  \u003cli\u003eRated to 550 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eUL Listed; meets SAE J512, SAE J513, and UNF thread standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style flare fitting for use with 3\/4-inch OD flared tubing systems using a 1-1\/16-14 UNF swivel nut thread, consistent with SAE J512 and SAE J513 flare fitting standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or plumber. Depressurize and isolate the line before disassembly or fitting installation. Ensure the tube end is properly flared to the correct 45-degree angle before seating the fitting — an improper flare is the leading cause of leaks at this joint type. Do not over-torque the swivel nut; hand-tighten first, then use a flare nut wrench to achieve a snug, leak-free seat without deforming the flare.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: 90 Degree Swivel Nut Elbow\u003c\/li\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: 3\/4 inches\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\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\u003eEnd Connection\u003c\/strong\u003e: Flare x Swivel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 550 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\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 166FSV-12-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542117744946,"sku":"166FSV-12-12","price":78.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb53df4430f32a04538e6a23eb6fbafe.jpg?v=1785892616","url":"https:\/\/voomisupply.com\/products\/parker-166fsv-12-12-brass-90-deg-swivel-nut-elbow-3-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
