Elkhart Products CP33-48 Lead-free Brass Union 3 in Cxc

Product Description

The ELKHART PRODUCTS CP33-48 is a lead-free cast brass union designed for copper-to-copper (CxC) solder connections in pressurized plumbing systems. Part of the International Cast Brass product line, this 3-inch union allows sections of copper pipe to be joined and later disconnected without cutting the line, which is essential for service work and future maintenance access. The lead-free brass construction meets current potable water requirements. Licensed plumbers install this fitting in residential and light commercial water distribution systems.

This union is suited for applications where a serviceable mechanical joint is required on a copper pipe run. The CxC solder-type ends accept standard copper tube, making it compatible with common sweat-soldering installation practices. It is well suited for use in domestic water supply lines, HVAC hydronic distribution piping, and other systems where copper is the specified pipe material. The 3-inch size targets main distribution lines and larger branch runs rather than fixture supply applications.

Key Features

• Lead-free brass construction meets NSF and safe drinking water compliance requirements
• CxC solder-type ends for standard sweat installation on copper tube
• 3-inch size for main distribution or larger branch piping runs
• Union design allows future disassembly without cutting the pipe
• Cast brass body from the International Cast Brass product line for consistent material quality

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 3-inch copper tube systems using CxC solder connections in residential and commercial plumbing applications.

Installation Notes

Installation is performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off and drain the affected water supply line fully before soldering to prevent steam pressure buildup and ensure a clean, dry joint. Use appropriate flux and lead-free solder rated for potable water service. Inspect the union nut and seat surfaces before assembly to confirm they are free of debris that could cause a leak at the joint face.
