This alloy composition delivers higher tensile strength and strong corrosion resistance compared to lower-grade import fittings with reduced copper content. The ns4-6 is designed for use in refrigeration and HVAC systems where a reliable flare connection is required. HVAC technicians and refrigeration service pros use this fitting when assembling or servicing refrigerant line sets and associated components.\u003c\/p\u003e\n\u003cp\u003eThis nut is suited for residential and commercial refrigeration and air conditioning applications. It is compatible with copper, brass, aluminum, steel, and plastic tubing where an acceptable flare can be generated. The 3\/8 inch nominal size makes it a common choice for standard refrigerant line connections. JB INDUSTRIES manufactures this fitting at their facility in Aurora, Illinois, maintaining tight dimensional tolerances for consistent field performance.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eForged brass construction using 65% copper and 35% zinc alloy for high tensile strength\u003c\/li\u003e\n  \u003cli\u003eShort body profile for use in tight or confined fitting locations\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant material suitable for refrigerant service environments\u003c\/li\u003e\n  \u003cli\u003eCompatible with copper, brass, aluminum, steel, and plastic tubing where proper flare is achievable\u003c\/li\u003e\n  \u003cli\u003eRated to handle vacuum pressures up to 5000 psi depending on size, material, and conditions\u003c\/li\u003e\n  \u003cli\u003eDomestically manufactured at the JB INDUSTRIES factory in Aurora, Illinois\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with copper, brass, aluminum, steel, and plastic tube provided an acceptable flare can be generated with the material.

Recover all refrigerant and depressurize the system before disassembling any flare connections. Ensure the mating tube end is properly flared using a calibrated flaring tool before torquing the nut onto the fitting. Do not overtighten, as brass flare nuts can crack or distort if excessive force is applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass (65% copper, 35% zinc)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStyle\u003c\/strong\u003e: Short Forged\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Vacuum Pressure\u003c\/strong\u003e: 5000 psi (depending on size, material, and conditions)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: United States (Aurora, Illinois)\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: JB INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ns4-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"JB INDUSTRIES","offers":[{"title":"Default Title","offer_id":51620629643570,"sku":"NS4-6","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0a1a2dae649c9905cab4cc6a7fe0440b.jpg?v=1787344834","url":"https:\/\/voomisupply.com\/products\/jb-industries-ns4-6-short-forged-refrigeration-nut-3-8-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
