It accepts 1\/8-inch tube OD with a 5\/16-28 UNF thread and is rated for working pressures up to 2800 psi and temperatures up to 250 degrees F. The inverted piloted design seats securely against a mating flare seat, maintaining a leak-free connection under pressure cycling. At 0.52 inches overall length, this compact fitting is suited for tight plumbing runs. Licensed HVAC technicians and refrigeration mechanics are the primary installers, though it also sees use in hydraulic and pneumatic lines.\u003c\/p\u003e\n\u003cp\u003eThis fitting is appropriate for residential and commercial HVAC systems, refrigeration equipment, and other fluid or gas lines where a flared inverted nut connection is specified. It is particularly common in low-pressure refrigerant lines, fuel systems, and instrument tubing where SAE J51 flare fittings are standard. The brass construction provides corrosion resistance in both wet and dry service environments, making it a reliable choice across a wide range of trade applications.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eInverted piloted nut design for secure, leak-resistant flare seating\u003c\/li\u003e\n  \u003cli\u003eBrass construction offers corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eRated to 2800 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003e5\/16-28 UNF thread matches SAE J51 and UL Listed standards\u003c\/li\u003e\n  \u003cli\u003eCompact 0.52-inch overall length suits tight installation spaces\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 flared tube assemblies requiring a 1\/8-inch tube OD inverted piloted nut with 5\/16-28 UNF thread, conforming to SAE J51 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified HVAC technician, refrigeration mechanic, or pipefitter familiar with flare fittings. Always depressurize and isolate the system before removing or installing any fitting. Ensure the tube end is cleanly cut, deburred, and properly flared to the correct SAE angle before seating the nut. Overtightening a flare nut can crack the flare seat or distort the tube, so follow the fitting manufacturer's tightening guidelines.\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 Piloted Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16-28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2800 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: 0.52 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE J51, UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: 41IFF-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540334674226,"sku":"41IFF-2","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c073cfaf65c1170f6402949fe3eaff70.jpg?v=1785852457","url":"https:\/\/voomisupply.com\/products\/parker-41iff-2-brass-inverted-piloted-flare-nut-1-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
