Unions like this one are a standard component in plumbing, HVAC, and refrigeration installations where serviceability is a priority. The fitting allows a technician to break a connection cleanly at a later date, making it a practical choice for equipment hookups, service valves, and branch connections that may need to be serviced over the life of the system. Licensed plumbers and HVAC-R technicians routinely install this type of fitting.\u003c\/p\u003e\u003cp\u003eThis union is suited for residential and light commercial copper tubing applications. It is appropriate for use in water supply lines, hydronic heating systems, and refrigerant line sets where a 7\/8-inch OD tube connection is required. The fitting ships in a box quantity of 25 units, making it a practical stocking item for service trucks and supply rooms handling routine copper pipework.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7\/8-inch connection size for standard copper tubing\u003c\/li\u003e\n\u003cli\u003eUnion design allows disconnection without cutting the line\u003c\/li\u003e\n\u003cli\u003eCopper construction provides corrosion resistance and durability in wet and refrigerant environments\u003c\/li\u003e\n\u003cli\u003eBox quantity of 25 units supports stocking for repeat-use applications\u003c\/li\u003e\n\u003cli\u003eCompatible with standard sweat (solder) joining methods\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard-stock union fitting for 7\/8-inch copper tubing installations in plumbing, HVAC, and refrigeration systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or HVAC-R technician following applicable local plumbing codes and IFGC or IPC guidelines where relevant. Shut off the water supply or isolate the refrigerant circuit and recover any refrigerant before beginning work on the line. The union nut and seat should be properly aligned before tightening to prevent cross-threading or joint failure. Solder connections must be made with the appropriate flux and filler material for the fluid service involved.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBasic Fitting Type\u003c\/strong\u003e: Union\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 7\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox Quantity\u003c\/strong\u003e: 25\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NDL INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: W8004\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NDL INDUSTRIES","offers":[{"title":"Default Title","offer_id":51383380279602,"sku":"W8004","price":19.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312670962.jpg?v=1782595180","url":"https:\/\/voomisupply.com\/products\/ndl-industries-w8004-copper-union-7-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
