It mates with a 5\/16-inch OD flared tube and uses a 1\/2-20 UNF thread to secure the flare fitting union. At 1.12 inches overall length, this long-nut profile provides added thread engagement compared to standard short nuts, which is important in applications with vibration or repeated service cycles. Rated to 1,200 psi maximum working pressure and 250 degrees F, it suits a range of hydraulic, pneumatic, refrigeration, and fuel line applications. Licensed HVAC and refrigeration technicians, plumbers, and pipefitters are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial HVAC systems, refrigeration equipment, hydraulic lines, and fuel delivery assemblies wherever a 45-degree SAE flare connection is specified. It conforms to SAE J512 and SAE J513 standards and carries a UL Listing, making it suitable for installations governed by those codes. Typical use involves securing a flared copper or aluminum tube to a flare fitting body or valve port in a pressurized fluid circuit.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree flare angle per SAE J512 and SAE J513 standards\u003c\/li\u003e\n  \u003cli\u003e1\/2-20 UNF thread for positive, leak-resistant engagement\u003c\/li\u003e\n  \u003cli\u003eRated to 1,200 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in refrigerant, fuel, and hydraulic service\u003c\/li\u003e\n  \u003cli\u003eUL Listed for use in regulated installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for 45-degree SAE flare assemblies using 5\/16-inch OD tubing with a 1\/2-20 UNF thread connection.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician, refrigeration mechanic, or qualified pipefitter familiar with SAE flare fittings. De-pressurize and isolate the line before disassembly; recover refrigerant where applicable per EPA Section 608 requirements. Hand-tighten the nut onto the flare fitting first to confirm thread alignment, then torque with a flare nut wrench to avoid deforming the flare seat. Do not overtighten brass fittings, as the material can crack under excessive force.\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: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2-20\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: 1,200 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: 1.12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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-5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540764033330,"sku":"41FL-5","price":29.71,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9dcaa75e77161917f715cd57bad396f1.jpg?v=1785863692","url":"https:\/\/voomisupply.com\/products\/parker-41fl-5-brass-flared-tube-long-nut-5-16-in-45-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
