The ELKHART PRODUCTS COU-12X38 is a copper reducer coupling with stop, sized to transition from 1/2 inch to 3/8 inch tubing in a sweat-solder connection. Part of the KLEENFIT product line, this fitting is pre-cleaned and bagged to meet cleanliness standards required for solder-ready installations. The integrated stop ensures consistent positioning of the tubing before soldering, reducing the chance of misalignment during assembly. Weighing just 0.024 pounds, it is lightweight and easy to handle in tight spaces. Licensed plumbers and HVAC technicians use this fitting in copper water supply, refrigerant, and general piping systems where a clean, reliable reducer joint is needed.
This coupling is suited for residential and light commercial plumbing and mechanical systems where 1/2 inch copper tubing must transition down to 3/8 inch. Typical applications include potable water supply lines, hydronic distribution branches, and refrigeration line sets. The CxC (copper by copper) solder-type connection is compatible with standard plumbing torch soldering methods. The KLEENFIT pre-cleaned and bagged format makes it well suited for installations where contamination control is a priority, such as systems that are flushed or pressure-tested after assembly.
Designed as an OEM-style replacement and standard-use reducer coupling for copper CxC solder applications in residential and commercial plumbing and mechanical piping systems.
Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with applicable local plumbing codes and IAPMO or IPC standards. Shut off and drain the water supply or depressurize the refrigerant line before beginning work. Clean and flux both tube ends before applying heat, and allow the joint to cool fully before pressure-testing. Do not overheat the fitting, as excessive heat can damage the copper and compromise the solder joint.
