It threads onto a compression fitting body to secure tubing with a 1\/4 inch outside diameter, creating a leak-resistant mechanical seal without soldering or brazing. Rated to 150 psi maximum working pressure and suitable for service between 0 and 150 degrees F, this nut handles a broad range of liquid and gas applications. At 0.38 inches overall length, it is a compact, purpose-built component that installs quickly with standard hand tools.\u003c\/p\u003e\n\u003cp\u003eThis compression nut is used in residential and light commercial installations where tubing connections must be made to valves, regulators, gauges, or other compression-end components. Typical applications include refrigerant line accessories, instrument tubing, pneumatic controls, and potable water lines where brass construction and compression-style end connections are specified. It is sold individually but carries a minimum order quantity of 5 units, making it practical for stocking in a service van or shop inventory.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and reliable sealing in fluid and gas service\u003c\/li\u003e\n  \u003cli\u003eCompression end connection eliminates the need for soldering or brazing during installation\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi maximum working pressure for a wide range of trade applications\u003c\/li\u003e\n  \u003cli\u003eCompatible with 1\/4 inch OD tubing for a precise, secure fit\u003c\/li\u003e\n  \u003cli\u003eCompact 0.38 inch overall length suits tight installation spaces\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range from 0 to 150 degrees F covers most residential and commercial service conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service component for compression-style tube fitting assemblies using 1\/4 inch outside diameter tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by licensed plumbers, HVAC technicians, or refrigeration mechanics. Shut off and depressurize the line before disassembling or replacing any compression fitting component. Hand-tighten the nut onto the fitting body first, then snug with a wrench — avoid overtightening, which can crack the ferrule or deform the tubing. Verify the connection is leak-free under system pressure before returning the system to service.\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\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: 61PN-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542091989298,"sku":"61PN-4","price":22.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ecb941c418d1fa1118b86ef42e00f04.jpg?v=1785891781","url":"https:\/\/voomisupply.com\/products\/parker-61pn-4-compression-tube-nut-brass-1-4-in-150-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
