The ELKHART PRODUCTS WP0-12-10 is a WROT copper reducer coupling with stop, sized at 3/4 inches by 5/8 inches with a sweat (solder) CxC connection. The integrated stop positions the pipe consistently during assembly, helping technicians achieve accurate, repeatable joints. Weighing 0.057 pounds, this fitting is machined from WROT copper, which offers tight dimensional tolerances and clean soldering surfaces suited for pressure piping applications. It is a standard component in residential and light commercial plumbing and HVAC hydronic systems wherever a reduction in tubing diameter is required at a solder joint.
This reducer coupling is used in copper tubing installations where a 3/4-inch line transitions to a 5/8-inch line. Typical applications include domestic water distribution, HVAC refrigerant piping rework (where code and system type permit soft copper), and hydronic heating supply and return lines. Plumbers, pipefitters, and HVAC technicians reach for this fitting during new construction, renovation, and repair work. Its compact profile at 0.97 inches by 1.56 inches by 0.97 inches fits in tight spaces common in mechanical chases and wall cavities.
Designed as an OEM-style replacement and standard-use fitting for copper tubing systems requiring a 3/4-inch to 5/8-inch solder-joint reduction.
Installation is performed by licensed plumbers or qualified HVAC technicians following applicable local plumbing codes and ASTM B88 copper tube standards. Shut off the water supply and fully drain the affected line before cutting and fitting. Clean both the tube end and fitting socket with emery cloth or a fitting brush, apply approved flux, and solder using lead-free solder where required by code. Do not apply flame directly to the fitting socket for extended periods, as overheating can oxidize the copper and compromise the joint.
