It provides a secure mechanical connection by compressing a ferrule against a tube end, creating a leak-resistant seal without soldering or brazing. Rated to 150 psi maximum working pressure, this nut handles temperatures from -40 degrees F to 200 degrees F. With an inside diameter of 1.94 inches, it is sized for larger-diameter tubing applications. Plumbers, HVAC technicians, and refrigeration mechanics are the primary installers of this type of fitting hardware.\u003c\/p\u003e\n\u003cp\u003eThis compression tube nut is suited for fluid and gas distribution systems in both residential and light commercial settings. It is used wherever a compression fitting assembly is required, including plumbing supply lines, pneumatic systems, and instrument tubing connections. The brass construction makes it appropriate for water, air, and compatible fluid service within its rated pressure and temperature range.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in water and air service\u003c\/li\u003e\n  \u003cli\u003eCompression end connection — no soldering or brazing required\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: -40 degrees F to 200 degrees F\u003c\/li\u003e\n  \u003cli\u003eInside diameter of 1.94 inches for larger-diameter tube fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression tube nut for use with Parker and standard compression fitting assemblies in plumbing, HVAC, and pneumatic tubing systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified HVAC and mechanical technicians. Shut off and depressurize the line before disassembly or fitting replacement. Hand-tighten the nut onto the fitting body first, then advance with a wrench — avoid over-tightening, which can crack the ferrule or deform the tube. Follow applicable IPC or IFGC guidelines for the system type being serviced.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Nut\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connection\u003c\/strong\u003e: Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 1.94 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 200 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: 61NTA-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541405761842,"sku":"61NTA-3","price":22.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e3e42a490aa016054195d70434a56ed.jpg?v=1785875020","url":"https:\/\/voomisupply.com\/products\/parker-61nta-3-compression-tube-nut-brass-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
