This fitting uses a flare-on-both-ends connection style, creating a reliable, leak-resistant joint in hydraulic, pneumatic, and fluid transfer lines. Rated to a maximum working pressure of 7,500 psi and a maximum working temperature of 500 degrees F, the 4 ETX-S is built for demanding service conditions. The 1\/4-inch tube OD sizing makes it a common choice in compact refrigeration, instrumentation, and hydraulic circuits where a union connection is needed for serviceability.\u003c\/p\u003e\u003cp\u003eThis tube union is suited for residential and commercial applications where two flared tube ends must be joined inline without additional fittings. Typical install scenarios include HVAC refrigerant line repairs, hydraulic control circuits, and instrumentation tubing assemblies. The 37-degree flare angle conforms to SAE J514 and ISO 8434-2 standards, making it compatible with standard JIC and SAE flare connections found throughout trade plumbing and HVAC work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare angle on both ends for a secure, leak-resistant seal\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 7,500 psi for high-demand hydraulic and fluid service\u003c\/li\u003e\n\u003cli\u003eRated to 500 degrees F maximum working temperature\u003c\/li\u003e\n\u003cli\u003eConforms to ISO 8434-2, SAE 070201, and SAE J514 standards\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in pressurized systems\u003c\/li\u003e\n\u003cli\u003e1\/4-inch tube OD fits standard small-bore tubing in HVAC, hydraulic, and instrumentation applications\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 1\/4-inch OD tubing with 37-degree SAE flare connections per SAE J514 and ISO 8434-2.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician, plumber, or hydraulic system technician as appropriate to the application. Always depressurize and purge the line before disassembling or installing flare fittings. Ensure both mating tube ends are properly flared to a 37-degree angle using a calibrated flaring tool before assembly. Tighten the union nuts to the fitting body using appropriate wrenches — do not use pipe dope or thread sealant on flare-style connections.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube OD\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlared Angle\u003c\/strong\u003e: 37 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Flare x Flare\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Working Pressure (Dynamic)\u003c\/strong\u003e: 7,500 psi\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 070201, SAE J514\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: 4 ETX-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544179212594,"sku":"4 ETX-S","price":25.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fa07661bfabb15c8b74e22a37b7f455b_b11baca4-c460-4eef-9123-8d8a97bc4d0e.jpg?v=1785925321","url":"https:\/\/voomisupply.com\/products\/parker-4-etx-s-steel-flared-tube-union-1-4-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
