The fitting uses a Compression x FNPT end connection configuration with a 9\/16-24 thread size on the compression side. Constructed from brass, it handles working pressures up to 400 psi and operates across a temperature range of -65 degrees F to 212 degrees F. This type of fitting is a standard component in fluid and gas line assemblies where a reliable, leak-resistant mechanical joint is required without soldering or welding. Licensed plumbers, HVAC technicians, and pipefitters are the typical installers.\u003c\/p\u003e\u003cp\u003eThe 66A-6A connector is suited for residential and light commercial applications where 3\/8-inch OD tubing must terminate at a female NPT threaded port. Common installations include instrument tubing, refrigeration line sets, pneumatic systems, and fuel or gas distribution lines. The SAE standard rating confirms the fitting meets recognized industry dimensional and performance requirements for this connection type.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompression x FNPT end connections for tool-assisted, solder-free assembly\u003c\/li\u003e\n\u003cli\u003e3\/8-inch tube outside diameter compatibility\u003c\/li\u003e\n\u003cli\u003e1\/8-inch NPT pipe size on the female threaded end\u003c\/li\u003e\n\u003cli\u003e400 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in fluid and gas service\u003c\/li\u003e\n\u003cli\u003eSAE rated for verified dimensional and performance compliance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation fitting for systems using 3\/8-inch OD tubing with 1\/8-inch NPT female threaded ports in compression fitting applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by a licensed plumber, HVAC technician, or pipefitter. Shut off and depressurize the line completely before disassembling or installing any compression fitting. Ensure the tubing end is cut cleanly and squarely and is free of burrs before inserting into the compression fitting body. Follow applicable codes such as the IPC or IFGC for pipe and tubing connection requirements in the relevant system type.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\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 FNPT\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\u003ePipe Size\u003c\/strong\u003e: 1\/8 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 9\/16-24\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: FPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 400 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 100 degrees C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: SAE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: CERROBRASS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 66A-6A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"CERROBRASS","offers":[{"title":"Default Title","offer_id":67909390139698,"sku":"66A-6A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3741a00ebccd9e54b974151aa4715606.jpg?v=1791186919","url":"https:\/\/voomisupply.com\/products\/cerrobrass-66a-6a-compression-tube-connector-3-8-od-1-8-npt","provider":"Voomi Supply","version":"1.0","type":"link"}
