It accepts a 1\/4-inch tube OD with a 7\/16-24 UNF thread and is rated for working pressures up to 1400 psi and temperatures up to 250 degrees F. At 0.56 inches overall length, this compact nut threads onto inverted flare fittings to lock refrigerant or hydraulic lines in place. Licensed HVAC technicians and refrigeration mechanics install this type of fitting during line set assembly, service valve connections, and component replacement work.\u003c\/p\u003e\n\u003cp\u003eThe PARKER 41IF-4 is suited for residential and light commercial HVAC systems, refrigeration equipment, and other fluid-handling applications requiring SAE J51 inverted flare connections. It is used wherever a 1\/4-inch OD copper or steel line must be terminated at an inverted flare seat, including suction and liquid line repairs, appliance connections, and retrofit installations. The UL Listed rating and SAE J51 compliance make it appropriate for applications with defined safety and performance requirements.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and reliable sealing at flare seats\u003c\/li\u003e\n  \u003cli\u003e7\/16-24 UNF inverted flare thread for SAE J51-compliant connections\u003c\/li\u003e\n  \u003cli\u003eRated to 1400 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eCompact 0.56-inch overall length suits tight installation spaces\u003c\/li\u003e\n  \u003cli\u003eUL Listed and SAE J51 compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement inverted flare nut for systems using 1\/4-inch OD tubing with 7\/16-24 UNF inverted flare connections per SAE J51.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of inverted flare fittings is typically performed by licensed HVAC technicians or refrigeration mechanics. Before servicing any refrigerant line, recover refrigerant per EPA Section 608 requirements and depressurize the system fully. Inspect the tube end for proper flare geometry before threading the nut; a damaged or under-flared seat will not seal at rated pressure. Do not overtighten brass fittings, as the threads and flare seat can be damaged by excessive torque.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Inverted Nut\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\/16-24\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1400 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: 0.56 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J51, UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 41IF-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538793005362,"sku":"41IF-4","price":26.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f0745f3a7d2910baf9408552dbf0ceab.jpg?v=1785826771","url":"https:\/\/voomisupply.com\/products\/parker-41if-4-brass-flared-tube-inverted-nut-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
