It mates with a compression sleeve and fitting body to create a leak-resistant mechanical connection on 1\/4-inch outside-diameter tubing. The nut features a 7\/16-24 thread and is rated for working pressures up to 300 psi across a wide service temperature range of -65 degrees F to 250 degrees F. Manufactured from brass to resist corrosion, this nut meets SAE J-512 standards. It is commonly installed by HVAC technicians, refrigeration mechanics, and plumbers working on small-bore tubing runs in equipment and utility lines.\u003c\/p\u003e\n\u003cp\u003eThis compression tube nut is suited for use in residential and light commercial applications where 1\/4-inch OD tubing connections are required. Typical installation scenarios include refrigeration line sets, instrument tubing, fuel lines, and hydraulic or pneumatic control circuits that call for an SAE J-512 compliant compression fitting system. The brass construction makes it compatible with copper and compatible soft-metal tubing used in these systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance for refrigerant, fuel, and fluid service environments\u003c\/li\u003e\n  \u003cli\u003e7\/16-24 thread size conforms to SAE J-512 for standardized fitment\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eFits 1\/4-inch outside-diameter tubing\u003c\/li\u003e\n  \u003cli\u003eCompression end connection — no soldering or brazing required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a SAE J-512 compliant compression tube nut for use with 1\/4-inch outside-diameter tubing and compatible Parker or equivalent SAE-standard compression fitting bodies and sleeves.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician, refrigeration mechanic, or plumber. Depressurize and isolate the line before disassembly or installation. Hand-tighten the nut onto the fitting body, then advance with a wrench per the fitting manufacturer's torque procedure — do not overtighten, as brass threads can be damaged. Verify no leaks under system pressure before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Compression Tube Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 7\/16-24\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 61C-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541282193714,"sku":"61C-4","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/00d6b67ccdd185c1e0112f23dcd88761.jpg?v=1785871337","url":"https:\/\/voomisupply.com\/products\/parker-61c-4-compression-tube-nut-1-4-in-od-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
