It accepts a 1\/2-inch tube OD and threads onto a 3\/4-16 UNF male fitting to secure a flared tube end in place. Rated to 750 psi maximum working pressure and 250 degrees F, this nut is built for demanding service in HVAC, refrigeration, and plumbing applications. At 1.62 inches overall length, the extended body provides additional engagement compared to a standard short nut, which aids in alignment during assembly. Licensed plumbers, HVAC technicians, and refrigeration mechanics are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis long nut is used wherever a 45-degree SAE flare connection is required on 1\/2-inch OD tubing. Common applications include refrigerant line sets, fuel gas lines, and hydraulic or pneumatic circuits where a secure, leak-free flare joint is needed. It meets SAE J512, SAE J513, and UL Listing standards, making it appropriate for both residential and light commercial installations. It is sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree flare end connection per SAE J512 and SAE J513\u003c\/li\u003e\n  \u003cli\u003e3\/4-16 UNF thread for positive engagement with standard male flare fittings\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and reliable sealing\u003c\/li\u003e\n  \u003cli\u003e750 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003e250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003e1.62-inch overall length provides extra body length versus standard short nuts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/2-inch OD tubing flared to a 45-degree angle and compatible with standard SAE 45-degree male flare fittings using 3\/4-16 UNF thread.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed HVAC technicians, refrigeration mechanics, or plumbers. Depressurize and isolate the line completely before disassembly or connection of any flare fitting. Ensure the tube end is properly flared to a 45-degree angle using a calibrated flaring tool before threading on the nut. Do not overtighten; follow applicable SAE and system manufacturer torque guidance. Verify compliance with local codes, including applicable sections of the IFGC or IPC where relevant.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Long Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: 45-Degree Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/2 inches\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\u003eOverall Length\u003c\/strong\u003e: 1.62 inches\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\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  \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: 41FL-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543044423986,"sku":"41FL-8","price":17.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cd4666e7fd4ea89c7433107a14e221b4.jpg?v=1785914385","url":"https:\/\/voomisupply.com\/products\/parker-41fl-8-brass-flared-tube-long-nut-1-2-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
