Rated for a maximum working pressure of 300 psi and a temperature range of -65 to 250 degrees F, this connector handles the pressure and thermal demands common in instrumentation, fuel, refrigeration, and hydraulic lines. The compression end eliminates the need for flaring or soldering, allowing a faster, repeatable connection. Plumbers, HVAC technicians, and instrumentation mechanics install this fitting where a tube-to-pipe transition is required in tight or service-accessible locations.\u003c\/p\u003e\u003cp\u003eThis connector suits residential and light commercial applications wherever a 5\/16-inch OD tube must terminate at a 1\/8-27 male pipe thread port. Typical install scenarios include fuel and oil lines, air and pneumatic circuits, and refrigerant or process fluid tubing runs that require a reliable metal-to-metal compression seal. The NPTF thread form provides a pressure-tight mechanical seal independent of sealant, though thread sealant is commonly applied per system requirements. Brass construction makes it compatible with a wide range of non-corrosive fluids and gases.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCompression x MNPT end connections for tube-to-pipe transitions without flaring or soldering\u003c\/li\u003e\n\u003cli\u003e300 psi maximum working pressure for demanding fluid and gas systems\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -65 to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance in non-corrosive media\u003c\/li\u003e\n\u003cli\u003eMeets SAE J-512 standard for compression tube fittings\u003c\/li\u003e\n\u003cli\u003eNPTF thread form delivers a pressure-tight mechanical seal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression fitting for systems using 5\/16-inch OD tubing with a 1\/8-27 NPTF male pipe thread port, conforming to SAE J-512.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation mechanic familiar with compression fittings and applicable codes. Shut off and depressurize the system fully before disassembly or installation. Hand-tighten the compression nut onto the fitting body, then advance with a wrench per standard compression fitting practice — do not overtighten, as brass fittings are susceptible to thread damage. Apply thread sealant to the MNPT threads as required by the system fluid, local codes, or manufacturer guidelines.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8-27\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: 300 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\u003eStandard\u003c\/strong\u003e: SAE J-512\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 68C-5-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541831024946,"sku":"68C-5-2","price":28.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b2203f1a41549deae603e55cc739b74b.jpg?v=1785886172","url":"https:\/\/voomisupply.com\/products\/parker-68c-5-2-compression-tube-connector-5-16-od-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
