Elkhart Products CP33-40 Lead-free Brass Cxc Union 2.5 in

Product Description

The ELKHART PRODUCTS CP33-40 is a lead-free cast brass union designed for copper-to-copper (CxC) solder connections in residential and commercial plumbing systems. Built to the International Cast Brass product line standard, this 2.5-inch union allows technicians to join, disconnect, and reconnect copper pipe sections without cutting, making it a practical fitting for service work and new installations alike. The lead-free brass construction meets current federal and state potable water standards, making it suitable for use in domestic water supply lines. Licensed plumbers and pipefitters are the primary installers of this fitting.

This union is sized at 2.5 inches and is intended for use in copper piping systems where a removable, pressure-rated joint is needed. It is commonly installed in mechanical rooms, boiler rooms, water service entrances, and anywhere a future disconnect point is required. The CxC solder end configuration makes it compatible with standard copper tubing in the corresponding nominal size.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off and depressurize the water supply and drain the line before soldering. Use appropriate flux and solder rated for potable water on all joint surfaces, and allow the fitting to cool fully before restoring water pressure. Inspect the union nut and seat for proper seating before final tightening.
