It accepts a 1\/2-inch tube OD and threads onto mating fittings with a 3\/4-16 UNF thread. Rated to 750 psi maximum working pressure and 250 degrees F, this nut is built for demanding service in hydraulic, refrigeration, and pneumatic systems. The short-body design suits tight-clearance installations where a standard-length nut would not seat properly. Licensed HVAC technicians, plumbers, and fluid-system technicians are the primary installers of this type of fitting.\u003c\/p\u003e\u003cp\u003eThe 14FSX-8 is suited for residential and light commercial applications where SAE 45-degree flare connections are standard. Typical use cases include refrigerant line sets, fuel lines, hydraulic tubing, and compressed-air systems that require a secure, leak-resistant mechanical joint. The forged brass construction resists corrosion in wet or chemically active environments, making it appropriate for both indoor and outdoor installations where copper or steel tubing is terminated with a 45-degree flare.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eForged brass construction for strength and corrosion resistance\u003c\/li\u003e\n\u003cli\u003e45-degree flare end connection per SAE J512 and SAE J513\u003c\/li\u003e\n\u003cli\u003e3\/4-16 UNF thread for positive, vibration-resistant engagement\u003c\/li\u003e\n\u003cli\u003e750 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eRated to 250 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eUL Listed; meets SAE J512, SAE J513 standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for systems using SAE 45-degree flared tube connections with a 1\/2-inch tube OD and 3\/4-16 UNF mating thread.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by licensed HVAC technicians, plumbers, or qualified fluid-system mechanics. Shut off and depressurize the system fully before disassembling any flare connection. Use a calibrated flaring tool to ensure the tube end meets SAE 45-degree flare geometry before seating the nut; a misformed flare is a primary cause of joint leakage. Do not overtighten — use a torque wrench and follow the applicable SAE or system-specific service procedure for the tubing material and diameter in use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Forged\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\u003eTube OD\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/4-16\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: 0.86 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 750 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 Listing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.08 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 14FSX-8\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541484896562,"sku":"14FSX-8","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aaba6dc112a7d032fec8fbf351c80adf_34d5dbbf-70cc-4fc0-9c03-07eb66a5a480.jpg?v=1785877498","url":"https:\/\/voomisupply.com\/products\/parker-14fsx-8-brass-short-flare-nut-1-2-in-od-3-4-16-unf","provider":"Voomi Supply","version":"1.0","type":"link"}
