It accepts a 3\/8-inch outside diameter tube on one end and a 1\/4-inch outside diameter tube on the other, making it suitable for reducing or transitioning between two tube sizes within the same run. Rated to 1400 psi maximum working pressure and capable of handling temperatures from -65 degrees F to 250 degrees F, this union is built for demanding fluid and gas distribution applications. Plumbers, HVAC technicians, and instrumentation installers use this fitting where a reliable, leak-resistant mechanical tube connection is required without soldering or flaring.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in residential and light commercial plumbing, HVAC refrigerant line accessories, pneumatic control systems, and instrumentation tubing runs where a compression-style union is preferred for ease of assembly and serviceability. The compression-by-compression end configuration allows field installation with standard tube cutters and wrenches, and the fitting can be disassembled and reassembled during system service. It is appropriate for copper, brass, or compatible steel tubing within its rated pressure and temperature range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x compression end connections for tool-free solderless assembly\u003c\/li\u003e\n  \u003cli\u003eReduces or transitions between 3\/8-inch and 1\/4-inch outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003e1400 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eWide temperature range from -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and reliable sealing\u003c\/li\u003e\n  \u003cli\u003eNPTF thread standard where applicable to fitting geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install compression union for tubing systems requiring a 3\/8-inch by 1\/4-inch outside diameter reduction connection with compression-style ends.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or instrumentation mechanics working on pressurized tubing systems. Shut off system pressure and bleed down the line before disassembling or installing any compression fitting. Ensure tube ends are cut square and deburred before inserting into the fitting body to achieve a proper compression seal. Do not overtighten the compression nut; follow standard compression fitting assembly practice for the tube material being used.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 inch x 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 1400 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 62CA-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544550211890,"sku":"62CA-6-4","price":24.92,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7e48f3702375241e0b595d4d78553dc6.jpg?v=1785929587","url":"https:\/\/voomisupply.com\/products\/parker-62ca-6-4-compression-tube-union-3-8x1-4-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
