Viega 77397 Propress Copper Tee 3/4 X 1/2 X 3/4 Inch

Product Description

The VIEGA 77397 is a zero-lead copper tee fitting designed for use in press-connect plumbing systems. It features a 3/4-inch by 1/2-inch by 3/4-inch configuration with press connections on all three ports, eliminating the need for soldering during installation. The fitting conforms to lead-free material requirements, making it suitable for potable water applications. Licensed plumbers install this type of fitting as part of ProPress-style press systems in both new construction and retrofit work. The copper construction provides reliable long-term corrosion resistance in standard water distribution service conditions.

This tee is used in residential and light commercial plumbing systems where press-fit copper connections are specified. The reduced center outlet at 1/2 inch makes it a practical choice for branch-off applications from a 3/4-inch main run, such as supplying a fixture branch from a trunk line. Installation requires a compatible press tool and the appropriate jaw set for the connection size. This fitting is intended for cold and hot water distribution piping within typical pressure and temperature ranges for copper press systems.
