It mates with 3\/16-inch OD tubing using a 3\/8-24 UNF thread and forms a leak-resistant seal through metal-to-metal flare contact. At 0.62 inches overall length, the short-body design is suited for tight-clearance installations. Rated to 1900 psi maximum working pressure and 250 degrees F, this fitting handles the thermal and pressure demands common in refrigeration lines, hydraulic circuits, and fuel systems. HVAC technicians, plumbers, and fluid-system mechanics are the typical installers.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial applications wherever 3\/16-inch OD tubing is joined with a 45-degree SAE flare connection. Common install scenarios include refrigerant line sets, fuel delivery tubing, hydraulic instrument lines, and compressed-air distribution where a short nut profile is required to clear adjacent components. Brass construction provides corrosion resistance compatible with a wide range of working fluids and gases.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e45-degree SAE flare end connection for leak-resistant metal-to-metal sealing\u003c\/li\u003e\n  \u003cli\u003e3\/16-inch tube OD with 3\/8-24 UNF thread — conforms to SAE J512 and SAE J513\u003c\/li\u003e\n  \u003cli\u003eRated to 1900 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n  \u003cli\u003eShort-body profile at 0.62 inches overall length for tight-clearance installations\u003c\/li\u003e\n  \u003cli\u003eUL Listed; meets SAE J512 and SAE J513 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 3\/16-inch OD tubing with 45-degree SAE flare connections and 3\/8-24 UNF threaded fittings.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians, plumbers, or fluid-system mechanics. Depressurize and isolate the line before disassembly or fitting installation. Ensure the tube end is properly flared to 45 degrees using a calibrated flaring tool before threading the nut — do not attempt to seat an unflared or improperly flared tube. Refer to SAE J512 and applicable system codes for assembly torque guidance from the system OEM.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Short 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: 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\u003eOverall Length\u003c\/strong\u003e: 0.62 inches\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\u003eStandards\u003c\/strong\u003e: SAE J512, SAE J513, UL Listed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 41FS-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539063013682,"sku":"41FS-3","price":22.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/13f5095f804812793f1115c9761454c4.jpg?v=1785834062","url":"https:\/\/voomisupply.com\/products\/parker-41fs-3-brass-flared-tube-short-nut-3-16-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
