This fitting joins two tube ends using a 37-degree flare seat on both sides, creating a leak-resistant metal-to-metal seal without the need for additional sealing compounds. Rated for a maximum working pressure of 7,500 psi, it is built for demanding service environments. Licensed HVAC technicians, plumbers, and fluid system installers use this type of union when connecting or extending tubing runs in tight or in-line configurations.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and commercial applications where 1\/4-inch OD tubing must be joined inline. Common install scenarios include refrigeration line sets, hydraulic circuits, and instrumentation tubing. The flare x flare end connection type makes it compatible with standard 37-degree flared tube fittings found throughout HVAC, refrigeration, and fluid power systems. Its compact steel construction holds up in both high-vibration and static installations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e37-degree flare seat on both ends provides a reliable metal-to-metal seal\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 7,500 psi suits high-pressure fluid and refrigeration lines\u003c\/li\u003e\n\u003cli\u003eSteel construction for durability in demanding mechanical environments\u003c\/li\u003e\n\u003cli\u003eFlare x flare end connection for straightforward inline tube joining\u003c\/li\u003e\n\u003cli\u003eFits 1\/4-inch OD tubing — a common size in HVAC, refrigeration, and hydraulic circuits\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 standard 37-degree flared connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with flared tube fitting assembly. Depressurize and isolate the tubing system completely before disassembling any fittings. Inspect the flare seats on both tube ends for damage or debris before torquing the union into place. Follow applicable system design codes and manufacturer torque guidelines for 37-degree flare fittings of this tube size.\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\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\u003c\/strong\u003e: 7,500 psi\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\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 KTX-S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542823829810,"sku":"4 KTX-S","price":69.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/69dda0ee56f9c8fdb3a00aa5b79a2116.jpg?v=1785908466","url":"https:\/\/voomisupply.com\/products\/parker-4-ktx-s-steel-flared-tube-union-1-4-in-37-degree","provider":"Voomi Supply","version":"1.0","type":"link"}
