This fitting uses a 37-degree flare angle on both ends, providing a reliable metal-to-metal seal rated for up to 6,000 psi maximum working pressure. The union configuration allows inline joining of two tube runs without requiring a fixed end, making it a standard component in hydraulic, pneumatic, refrigeration, and fuel line assemblies. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting during new construction and service work on pressurized tubing systems.\u003c\/p\u003e\u003cp\u003eThis flared tube union is suited for residential and commercial applications where a removable, pressure-rated inline connection is required. The 3\/8 inch tube outside diameter and flare-by-flare end configuration make it compatible with standard JIC-style 37-degree flared tubing circuits. Typical install scenarios include hydraulic power units, machine tool plumbing, fuel supply lines, and refrigerant or oil tubing runs where tube union access points are needed for service or system modification.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare angle on both ends for a reliable metal-to-metal seal\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 6,000 psi suits demanding hydraulic and pneumatic systems\u003c\/li\u003e\n\u003cli\u003eFlare x Flare end connection allows inline union without fixed-end constraints\u003c\/li\u003e\n\u003cli\u003eSteel construction provides durability in high-pressure and high-cycle environments\u003c\/li\u003e\n\u003cli\u003e3\/8 inch tube outside diameter fits standard JIC-style flared tubing\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 3\/8 inch outside diameter tubing with 37-degree JIC flare connections rated to 6,000 psi working pressure.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified pipefitter, plumber, or HVAC technician familiar with flared tube fittings and applicable pressure system codes. Always depressurize and isolate the line before disassembly or installation. Ensure tube ends are properly flared to the 37-degree angle using a calibrated flaring tool before assembly. Over-tightening the union nut can deform the flare seat and compromise the seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x 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 Outside Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 6,000 psi\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: PARKER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6 ETX-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538931777842,"sku":"6 ETX-S","price":23.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa07661bfabb15c8b74e22a37b7f455b.jpg?v=1785830068","url":"https:\/\/voomisupply.com\/products\/parker-6-etx-s-steel-flared-tube-union-3-8-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
