Elkhart Products 9001600CB Copper Coupling 1x3/8 Inch

Product Description

The ELKHART PRODUCTS 9001600CB is a copper reducing coupling designed for connecting copper tubing in plumbing and HVAC piping systems. This fitting measures 1 inch on one end and 3/8 inch on the other, making it suitable for reducing down between two different tube sizes. It ships cleaned and bagged to maintain interior cleanliness, keeping the fitting free of debris and oxidation until installation. Licensed plumbers and HVAC technicians rely on this type of fitting for sweat-solder connections in both residential and light commercial applications.

This coupling is used in copper piping systems where a reduction between 1 inch and 3/8 inch tubing is required. Common applications include domestic water supply lines, hydronic heating systems, refrigerant piping, and general plumbing rough-in work. The cleaned and bagged packaging is particularly useful on job sites where keeping fittings contaminant-free prior to soldering is a code and quality requirement.

Key Features

• Reducing coupling connects 1 inch to 3/8 inch copper tubing
• Cleaned and bagged to maintain interior cleanliness before installation
• Copper construction for corrosion resistance and reliable sweat-solder joints
• Compatible with standard sweat (solder) joining methods

Compatibility

Designed as an OEM-style replacement and standard-use copper reducing coupling for residential and commercial copper piping systems requiring a 1 inch to 3/8 inch transition.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician following applicable local plumbing codes and IAPMO or IPC guidelines. Shut off and depressurize the water or refrigerant system fully before cutting into any existing line. Clean mating tube ends and the fitting socket with emery cloth and flux before soldering. Do not overheat the fitting during the sweat process, as excessive heat can damage the copper or draw flux into the line.
