Zurn Pex qac33 Pex Compression Union 1/2 Inch

Product Description

The ZURN PEX qac33 is a 1/2 inch PEX compression union fitting designed for joining pipe sections in potable water systems. This coupler provides a reliable mechanical connection without the need for soldering or specialized crimp tools, making it a practical choice for repair and new installation work. The fitting is constructed from PEX material and measures approximately 1.35 inches in height and 4.05 inches in width. At 0.11 pounds, it is lightweight and easy to handle in tight spaces. Licensed plumbers and experienced pipe fitters typically specify this type of fitting for both residential and light commercial water distribution lines.

The qac33 is suited for use in potable water systems where PEX, copper, CPVC, or polybutylene pipe is present. Its compression-style design allows for straightforward connections in retrofit scenarios where existing pipe materials may vary. This makes it a versatile option for service calls involving mixed-material plumbing systems. The fitting is appropriate for in-wall, under-slab, and exposed plumbing runs where a union connection is required to allow future serviceability.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and IPC requirements. Shut off the water supply and relieve system pressure before beginning any fitting work. Ensure pipe ends are cut cleanly and deburred before seating into the compression fitting. Do not overtighten compression nuts, as this can deform the fitting seat and cause leaks.
