It accepts 3\/16 inch tube OD with a 3\/8-24 thread and a 45-degree flare seat. The inverted nut design locks onto the flared tube end, creating a metal-to-metal seal rated for up to 2000 psi working pressure and temperatures up to 250 degrees F. This fitting is appropriate for professional installations in HVAC, plumbing, and fluid-transfer systems where SAE and ASME standards compliance is required.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial applications involving small-diameter tubing runs. Typical use cases include brake line repairs, fuel system connections, and refrigerant or hydraulic line assemblies where a 3\/16 inch tube OD with an inverted 45-degree flare end is specified. It is installed by HVAC technicians, plumbers, and automotive or industrial mechanics working with pre-flared tubing. No specific compatible equipment model numbers are provided in the product data.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eInverted 45-degree flare seat provides a tight metal-to-metal seal under pressure\u003c\/li\u003e\n\u003cli\u003eRated for up to 2000 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eRated for temperatures up to 250 degrees F (121 degrees C)\u003c\/li\u003e\n\u003cli\u003e3\/8-24 thread size fits standard inverted flare fittings for 3\/16 inch OD tubing\u003c\/li\u003e\n\u003cli\u003eMeets ASA, ASME, MS, and SAE 040110 standards\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in fluid-transfer and hydraulic service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement inverted flare nut for systems using 3\/16 inch OD tubing with a 45-degree flare end and 3\/8-24 thread specification.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with flared tube fittings and applicable codes such as SAE or ASME standards for fluid systems. Always depressurize and purge the line before removing or installing any tube fitting. Hand-start the nut onto the mating fitting before applying a wrench to avoid cross-threading. Inspect the flare seat and tube flare for damage before assembly, as a deformed seat will compromise the seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Inverted Nut\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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\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\u003eOverall Length\u003c\/strong\u003e: 0.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2000 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: ASA, ASME, MS, SAE 040110\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: EATON\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 105X3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51538978439474,"sku":"105X3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fbb2ae6ba6ce7330cec372d33d37c7ff.jpg?v=1785831629","url":"https:\/\/voomisupply.com\/products\/eaton-105x3-steel-inverted-nut-3-16-in-od-3-8-24-45-deg-flare","provider":"Voomi Supply","version":"1.0","type":"link"}
