Ndl Industries W1025 Copper Reducing Coupling 5/83/8 Cxc

Product DescriptionThe NDL INDUSTRIES W1025 is a copper reducing coupling designed to connect two copper tubes of different diameters in a sweat-soldered piping system. Joining a 5/8-inch socket to a 3/8-inch socket with a C x C (copper-to-copper) connection type, this fitting allows plumbers and HVAC technicians to step down tubing size within a refrigerant, potable water, or hydronic line. The all-copper construction provides corrosion resistance and reliable soldered joints under typical service pressures. It is sold in a box quantity of 100, making it practical for contractors stocking a service vehicle or completing multi-fixture roughed-in work.This reducing coupling is suited for residential and light commercial plumbing and HVAC applications where a transition from 5/8-inch to 3/8-inch copper tubing is required. Common install scenarios include domestic water supply lines, refrigerant distribution piping, and hydronic heating loops. The sweat-connect design is standard practice for licensed plumbers and HVAC mechanics working with hard copper tubing in new construction and retrofit projects alike.Key FeaturesReduces from 5/8-inch to 3/8-inch copper tube in a single fittingC x C connection type for sweat-soldered joints on both endsAll-copper construction for corrosion resistance in water and refrigerant serviceSold in a box quantity of 100 for contractor-level supplyCompatibilityDesigned as an OEM-style sweat-fit reducing coupling compatible with standard 5/8-inch and 3/8-inch hard copper tubing per ASTM B88 and B280 specifications in plumbing and HVAC applications.Installation NotesInstallation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IFGC or IPC guidelines. Shut off and depressurize the water or refrigerant system completely before cutting into any existing line. Clean the tube ends and fitting sockets thoroughly and apply flux before soldering to ensure a leak-free joint. Allow soldered joints to cool fully before pressurizing the system.Technical SpecificationsBasic Fitting Type: CouplingSpecific Fitting Type: Reducing CouplingConnection Type: C x CConnection Size: 5/8 inches x 3/8 inchesBox Quantity: 100Standard InformationBrand: NDL INDUSTRIESManufacturer Part Number: W1025
