It functions as the threaded retention component in a flared tube fitting assembly, securing the flared tube end against a mating fitting seat to form a leak-resistant mechanical joint. Rated to a maximum working temperature of 500 degrees F, it is suited for hydraulic, pneumatic, fuel, and refrigeration line applications where a dependable flare connection is required. Licensed HVAC technicians, plumbers, and fluid power mechanics routinely install this hardware during line fabrication or repair work.\u003c\/p\u003e\n\u003cp\u003eThis tube nut is used in residential and light commercial systems wherever 37-degree SAE flare fittings are specified. Typical applications include refrigerant line sets, hydraulic tubing assemblies, fuel delivery lines, and compressed air circuits. The 37-degree flare geometry conforms to SAE J514 and ISO 8434-2, making it compatible with standard JIC and SAE flare fitting systems found across HVAC, fluid power, and plumbing installations. Overall length of 0.62 inches keeps the assembly compact in tight routing spaces.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e37-degree flare angle meets SAE J514, SAE 070110, and ISO 8434-2 standards\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability in high-temperature and high-pressure line applications\u003c\/li\u003e\n  \u003cli\u003eRated for service up to 500 degrees F (260 degrees C)\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch tube OD sizing fits standard small-diameter tubing used in HVAC and fluid systems\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 0.62 inches suits confined routing environments\u003c\/li\u003e\n  \u003cli\u003eSold individually; order in multiples of 5 per manufacturer minimum order requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 1\/4-inch OD tubing in standard 37-degree SAE JIC flare fitting assemblies conforming to SAE J514 and ISO 8434-2 specifications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified HVAC technicians, plumbers, or fluid power mechanics. Depressurize and isolate the line completely before disassembling any flare fitting. Inspect the tube flare for cracks or out-of-round condition before threading the nut; a damaged flare will not seal reliably. Torque the nut to the fitting manufacturer's specification using a calibrated torque wrench — do not rely on feel alone on small-diameter fittings.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/4 inch\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 Temperature\u003c\/strong\u003e: 500 degrees F (260 degrees C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 8434-2, SAE 070110, SAE J514\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 4 BTX-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542796108082,"sku":"4 BTX-S","price":20.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a72e86b3530527cee5d8e68b9a5f95ec_349029e5-c659-406b-a2ae-21259a1f4a9a.jpg?v=1785907670","url":"https:\/\/voomisupply.com\/products\/parker-4-btx-s-steel-flared-tube-nut-1-4-in-od-37-deg","provider":"Voomi Supply","version":"1.0","type":"link"}
