It accepts a 1\/4-inch tube OD on the flare end and uses a 7\/16-20 UNF swivel nut thread on the mating end. The swivel nut design allows the fitting to rotate freely during installation, reducing torsional stress on the tubing and simplifying alignment in tight spaces. Rated to 1,400 psi maximum working pressure and 250 degrees F, this fitting is built for demanding service environments where a reliable, leak-free 90-degree direction change is required. Brass construction provides corrosion resistance and compatibility with common refrigerant and hydraulic fluid lines.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial HVAC systems, refrigeration equipment, and hydraulic tubing assemblies wherever a 90-degree flare-to-swivel transition is needed. Typical applications include refrigerant line routing, fuel system connections, and any tubing run requiring a right-angle change of direction with a standard SAE 45-degree flare interface. It is installed by HVAC technicians, refrigeration mechanics, and hydraulic system assemblers working with 1\/4-inch OD flared tubing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree swivel nut elbow allows free rotation during torque-up, reducing tube twist\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch tube OD flare end with 7\/16-20 UNF swivel nut thread\u003c\/li\u003e\n  \u003cli\u003eRated to 1,400 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eMaximum working temperature of 250 degrees F (121 degrees C)\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in refrigerant and hydraulic fluid service\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J512, SAE J513, and UL Listing standards\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 1\/4-inch OD SAE 45-degree flared tubing with 7\/16-20 UNF threaded connections, in accordance with SAE J512 and SAE J513 standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician or refrigeration mechanic. Before servicing any refrigerant or hydraulic line, depressurize and recover the system fluid per applicable safety codes. Use a flare nut wrench to avoid rounding the swivel nut, and confirm the tube end is properly flared before final assembly. Do not overtighten; refer to fitting manufacturer torque guidelines for SAE flare fittings in the applicable service documentation.\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 OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-20\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\u003eFlared Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1,400 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\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listing\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-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539422511410,"sku":"166FSV-4-4","price":24.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c095bd2736b814ae31c22e9134a10547.jpg?v=1785839939","url":"https:\/\/voomisupply.com\/products\/parker-166fsv-4-4-brass-90-deg-flare-swivel-nut-elbow","provider":"Voomi Supply","version":"1.0","type":"link"}
