Elkhart Products 9003850CB Copper Coupling 4 Inches

Product Description

The ELKHART PRODUCTS 9003850CB is a 4-inch copper coupling designed for use in pressure piping systems across residential and commercial plumbing applications. Supplied cleaned and bagged, this fitting arrives ready for immediate use without additional preparation before soldering. The cleaned and bagged packaging maintains the interior and exterior surfaces free of oils, oxidation, and debris, which supports consistent solder joints and reduces rework. Plumbers and pipefitters install this coupling to join two lengths of 4-inch copper tubing in a straight run. The full-size coupling conforms to standard copper fitting dimensions for reliable, leak-free connections.

This coupling is suited for potable water supply lines, hydronic heating distribution, and general pressure piping where 4-inch copper tube is specified. The 4-inch size is common in main service entries, large domestic water distribution mains, and mechanical room piping in commercial and multifamily construction. Licensed plumbers working under IPC or local adopted codes will find this fitting compatible with standard sweat-solder joining methods used throughout the trade.
