It threads onto a male flare fitting to secure a 45-degree flared tube end, creating a leak-resistant mechanical seal. The nut accepts 3\/16 inch tube OD and features a 3\/8-24 UNF thread. Rated to 1900 psi maximum working pressure and a maximum working temperature of 250 degrees F, this fitting is suited for moderate- to high-pressure service in demanding environments. Licensed HVAC technicians, plumbers, and fluid-systems mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis long nut is used wherever a 45-degree SAE flare connection must be made or remade in tight-clearance installations where a longer nut body aids thread engagement or torquing. Common applications include refrigerant line sets, fuel delivery tubing, hydraulic instrument lines, and low-diameter copper or steel tubing assemblies in both residential and light commercial equipment. The 3\/16 inch tube OD and 3\/8-24 UNF thread size are standard in many OEM and aftermarket flare fittings in these systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree SAE flare seat mates with standard SAE J512 and SAE J513 flare fittings\u003c\/li\u003e\n  \u003cli\u003e3\/16 inch tube OD with 3\/8-24 UNF thread for precise, secure engagement\u003c\/li\u003e\n  \u003cli\u003e1900 psi maximum working pressure rated for moderate- to high-pressure fluid lines\u003c\/li\u003e\n  \u003cli\u003e250 degrees F maximum working temperature suitable for a wide range of fluid types\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in refrigerant, fuel, and hydraulic fluid service\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 0.81 inches fits standard tube assemblies without clearance issues\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 45-degree SAE flare fittings per SAE J512 and SAE J513 standards, accepting 3\/16 inch OD tubing with a 3\/8-24 UNF male thread counterpart.

Always depressurize and evacuate the line before disassembling or installing any flare fitting. Ensure the tube end is properly flared to the correct 45-degree angle using a calibrated flaring tool before threading the nut; an improperly flared tube will result in leaks regardless of thread torque. Refer to SAE J512 and SAE J513 specifications for proper assembly practices.\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\u003eTube OD\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1900 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\u003eOverall Length\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 41FL-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542491922738,"sku":"41FL-3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf6ee1de6c4f1770c2d567d052211592.jpg?v=1785901828","url":"https:\/\/voomisupply.com\/products\/parker-41fl-3-brass-flared-tube-long-nut-3-16-in-45-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
