It accepts 5\/8-inch tube OD with a 45-degree flare seat and connects via a 7\/8-14 UNF swivel nut thread. The swivel end allows the nut to rotate freely during installation, reducing the risk of twisting or distorting soft copper or aluminum tubing. Rated to 650 psi maximum working pressure and 250 degrees F, this fitting handles the demands of refrigerant lines, hydraulic circuits, and fuel system connections where a directional change is required in tight spaces.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial HVAC refrigerant line sets, automotive and industrial hydraulic lines, fuel systems, and any application requiring a 90-degree flare elbow with a swivel connection. HVAC technicians, refrigeration mechanics, and fluid-power technicians typically install this type of fitting when routing copper or steel tubing around corners or obstructions. It conforms to SAE J512 and SAE J513 standards and carries a UL Listing, making it appropriate for regulated installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree elbow body with 45-degree flare seat for directional tube routing\u003c\/li\u003e\n  \u003cli\u003eSwivel nut end rotates freely to simplify assembly without torquing the tube\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and good machinability for repeated service\u003c\/li\u003e\n  \u003cli\u003eRated to 650 psi maximum working pressure for refrigerant and hydraulic applications\u003c\/li\u003e\n  \u003cli\u003eCompliant with SAE J512, SAE J513, and UL Listing requirements\u003c\/li\u003e\n  \u003cli\u003e7\/8-14 UNF thread size is a standard refrigeration and hydraulic fitting dimension\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 5\/8-inch OD flared tubing with 7\/8-14 UNF threaded connections, consistent with SAE J512 and SAE J513 standard flare fittings used in refrigeration and hydraulic plumbing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eLicensed HVAC technicians, refrigeration mechanics, or qualified fluid-power technicians should install this fitting. Before servicing any refrigerant or hydraulic line, recover the refrigerant or relieve system pressure in accordance with applicable codes and safety procedures. Use a proper flaring tool to prepare the tube end to a 45-degree flare before seating the nut; do not overtighten, as brass fittings can distort the flare seat. Verify thread engagement and check for leaks after system pressurization.\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\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 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\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: 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\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.27 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-10-10\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544609915186,"sku":"166FSV-10-10","price":39.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e62fd0b5faa53678d8e8f78f9c35b1f5.jpg?v=1785931373","url":"https:\/\/voomisupply.com\/products\/parker-166fsv-10-10-brass-90-deg-swivel-nut-elbow-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
