It accepts 3\/8-inch tube OD with a 45-degree flare angle and uses a 5\/8-18 UNF thread on the swivel end. The fitting is rated to 1000 psi maximum working pressure and handles temperatures up to 250 degrees F, making it suitable for high-pressure refrigerant lines and hydraulic circuits. HVAC technicians and plumbers use this elbow to make a 90-degree directional change in a tubing run while maintaining a leak-free flared connection. The swivel nut design simplifies alignment during assembly without rotating the tubing itself.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial HVAC systems, refrigeration equipment, and fluid power plumbing where a 90-degree flare elbow is needed to route tubing through tight or angled spaces. It is well suited for copper tubing lines connecting condensers, evaporators, and other refrigerant circuit components. Installers working to SAE J512 and SAE J513 flare standards will find the 166FSV-6-6 a direct fit in those system configurations. The UL-listed rating adds an extra layer of confidence for installations subject to inspection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree swivel nut elbow with 45-degree flare angle for directional tubing routing\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch tube OD, Flare x Swivel end connections\u003c\/li\u003e\n  \u003cli\u003e5\/8-18 UNF thread standard\u003c\/li\u003e\n  \u003cli\u003e1000 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e250 degrees F maximum working temperature\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 3\/8-inch OD flared tube systems conforming to SAE J512 and SAE J513 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber. Always recover refrigerant and depressurize the system before disconnecting or installing flare fittings. Use a calibrated flaring tool to produce a proper 45-degree flare seat; an improperly formed flare is a leading cause of leaks. Tighten the swivel nut to the fitting body by hand first, then use a flare nut wrench to achieve a snug, leak-free seat without over-torquing the brass threads.\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\/8 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: 5\/8-18\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: 1000 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: 0.12 pounds\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-6-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539507478834,"sku":"166FSV-6-6","price":32.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1683bab7e3791635a5a92a68e6770372.jpg?v=1785842130","url":"https:\/\/voomisupply.com\/products\/parker-166fsv-6-6-brass-swivel-nut-flare-elbow-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
