This long nut secures the ferrule and tubing against a fitting body, creating a leak-resistant mechanical connection without soldering or flaring. It is suited for 3\/16-inch outside diameter tubing and is commonly installed in refrigeration, HVAC, and fluid-handling lines where compression fittings are the specified connection method. Plumbers, HVAC technicians, and refrigeration mechanics install this type of hardware during new assembly or repair work on copper or compatible tubing runs.\u003c\/p\u003e\n\u003cp\u003eThis long nut is used in residential and light commercial applications wherever compression-style connections are specified. Typical install scenarios include refrigerant line accessories, instrument tubing, fuel lines, and other low-pressure fluid or gas circuits that require a removable, reusable mechanical joint. The 3\/16-inch tube OD sizing fits common small-bore copper and brass tubing used throughout HVAC and plumbing systems. It is sold in a package quantity of 10, making it practical for service stock or multi-point jobs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance and reliable sealing under compression load\u003c\/li\u003e\n  \u003cli\u003eLong nut profile allows full thread engagement for a secure, leak-resistant joint\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/16-inch tube outside diameter\u003c\/li\u003e\n  \u003cli\u003eCompression end connection — no solder, flux, or flaring required\u003c\/li\u003e\n  \u003cli\u003eSold in a 10-piece package for service and inventory convenience\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style compression long nut for use with standard compression fitting bodies and ferrules accepting 3\/16-inch outside diameter tubing in HVAC, refrigeration, and plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed HVAC technicians or plumbers. Before servicing any line, shut off and isolate the system from pressure and, where applicable, recover any refrigerant per EPA Section 608 requirements. Hand-tighten the long nut onto the fitting body before applying a wrench to avoid cross-threading the brass threads. Do not overtighten — brass compression fittings require only moderate torque to seat the ferrule and seal the joint.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Long 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: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KP78505\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51539621249330,"sku":"KP78505","price":36.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_2823187c-95f7-42f2-b034-d4320d135ba4.jpg?v=1785843612","url":"https:\/\/voomisupply.com\/products\/eaton-kp78505-compression-long-nut-brass-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
