Elkhart Products WP0-16-10 Copper Reducing Coupling

Product Description

The ELKHART PRODUCTS WP0-16-10 is a copper reducing coupling designed to connect two pipes of different diameters in a single inline joint. It transitions from a 1 inch end to a 5/8 inch end, making it a practical fitting for reducing line size within a copper piping system. This type of fitting is soldered in place by a licensed plumber or HVAC technician and is a standard component in both plumbing and refrigeration piping work. Its all-copper construction ensures compatibility with soft and hard copper tubing commonly used in residential and light commercial applications.

This reducing coupling is suited for use in potable water supply lines, hydronic heating systems, HVAC refrigerant piping, and general plumbing rough-in work where a diameter transition is required. It is installed wherever a run of 1 inch copper line must be reduced to 5/8 inch, such as branch lines, equipment connections, or rerouted piping sections. It is commonly stocked by plumbing and HVAC contractors for service and new construction work.

Key Features

• Transitions from 1 inch to 5/8 inch copper pipe in a single fitting
• All-copper construction for reliable soldered joints
• Inline reducing design eliminates the need for additional adapters
• Compatible with standard sweat-solder installation methods
• Suitable for potable water, HVAC, and hydronic piping applications

Compatibility

Designed as an OEM-style replacement and standard-use fitting for copper piping systems requiring a 1 inch to 5/8 inch diameter reduction via sweat connection.

Installation Notes

Installation should be performed by a licensed plumber or HVAC technician following applicable local plumbing codes and IAPMO or IPC standards. Shut off and drain the water supply or isolate the refrigerant circuit before cutting into the existing line. Clean and flux both pipe ends thoroughly before applying solder to ensure a leak-free joint. Do not use open flame near flammable materials, and allow the fitting to cool completely before restoring system pressure.
