It features a compression end on one side and a male NPT (MNPT) end on the other, making it a reliable solution for converting or terminating tube runs at threaded fittings. Rated to 200 psi maximum working pressure and a temperature range of -65 to 250 degrees F, this connector handles the demands of refrigeration, pneumatic, and fluid-handling systems. The brass construction resists corrosion and meets SAE J-512 standards. Licensed HVAC and plumbing technicians are the primary installers of this fitting.\u003c\/p\u003e\n\u003cp\u003eThe 68C-6-4 is suited for residential and light commercial HVAC systems, pneumatic control lines, fuel systems, and general fluid distribution applications where a compression tube must terminate or transition at a male NPT port. The compression-style connection allows for a secure, leak-resistant joint without soldering or flaring. This fitting is commonly used in control tubing, instrument lines, and low-pressure fluid circuits where SAE J-512 compliance is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCompression x MNPT end connections for tool-accessible, no-solder installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch tube OD compression end with 1\/4-18 NPTF male thread\u003c\/li\u003e\n  \u003cli\u003e200 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -65 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eMeets SAE J-512 standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression fitting for use in systems requiring a 3\/8-inch OD tube connection to a 1\/4-18 NPTF male port, consistent with SAE J-512 applications in HVAC, pneumatic, and fluid-handling installations.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is typically installed by licensed HVAC technicians, plumbers, or pipefitters. Shut off system pressure and depressurize the line completely before removing or installing any compression fitting. Hand-tighten the compression nut onto the tube, then advance with a wrench to achieve a proper bite on the ferrule — do not overtighten. Verify the connection for leaks before returning the system to service, in accordance with applicable codes such as the IPC or IFGC.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Connector\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 MNPT\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\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 200 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\u003eStandards\u003c\/strong\u003e: SAE J-512\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: 68C-6-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540435763506,"sku":"68C-6-4","price":29.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/992406d9b541fc5e7cc3209858c49afc.jpg?v=1785855074","url":"https:\/\/voomisupply.com\/products\/parker-68c-6-4-compression-tube-connector-3-8-od-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
