It uses a solder cup connection, allowing it to be sweated onto the pipe end with standard soldering tools for a clean, pressure-tight closure. This fitting conforms to the C617 designation for copper solder-joint pressure fittings and is sized for 3\/8-inch copper tubing. It is a standard fitting installed by licensed plumbers and HVAC technicians during new installations, system modifications, or when capping off unused branch lines.\u003c\/p\u003e\n\u003cp\u003eThis cap is suited for residential and light commercial plumbing and hydronic or refrigerant-adjacent copper piping systems where a permanent, soldered end closure is required. Common applications include capping supply or return lines during phased construction, decommissioning branch runs, or isolating a section of pipe during repair work. The lead-free construction meets current potable water installation requirements under the Safe Drinking Water Act, making it appropriate for domestic water systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLead-free construction compliant with potable water installation standards\u003c\/li\u003e\n  \u003cli\u003eSolder cup connection for a permanent, sweated joint\u003c\/li\u003e\n  \u003cli\u003eC617 copper solder-joint pressure fitting designation\u003c\/li\u003e\n  \u003cli\u003eSized for 3\/8-inch copper tubing end termination\u003c\/li\u003e\n  \u003cli\u003eSeals the open end of pipe to prevent contamination or pressure loss\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solder-joint cap for standard 3\/8-inch copper tubing used in residential and commercial plumbing and HVAC piping systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed plumber or HVAC technician using standard copper soldering tools including a torch, flux, and lead-free solder. Shut off and depressurize the supply line and ensure the pipe end is dry before soldering, as moisture will prevent a sound joint. Follow all applicable local plumbing codes and IAPMO or IPC requirements for solder-joint fittings on potable water systems. Allow the joint to cool completely before restoring system pressure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Solder Cup (Sweat)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Standard\u003c\/strong\u003e: C617\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead-Free\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.28 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: EA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 10\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: NIBCO INC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W01840D\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NIBCO","offers":[{"title":"Default Title","offer_id":51524876075314,"sku":"W01840D","price":19.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f86bc4d88ac3bc0259367591984137e7_6b67b8d6-6e70-41e7-a68f-8159c4f9f97c.jpg?v=1785460350","url":"https:\/\/voomisupply.com\/products\/nibco-inc-w01840d-copper-tube-cap-3-8-inch-lead-free","provider":"Voomi Supply","version":"1.0","type":"link"}
