Viega 77477 Propress Zero Lead Copper Tee 2 Inch

Product Description

The VIEGA 77477 is a zero-lead copper press tee designed for 2-inch press-by-press-by-press connections in commercial and residential plumbing systems. This fitting is part of the Viega ProPress system, which uses a cold-press joining method to create watertight, permanent connections without open flame or soldering. The tee is manufactured from copper that exceeds the wall thickness of Type K copper, providing a robust fitting suitable for potable water, heating, and cooling distribution piping. The 77477 meets or exceeds applicable North American plumbing codes and lead-free standards.

This fitting is used in new construction and retrofit plumbing installations where speed and reliability are priorities. The ProPress system is widely adopted in commercial mechanical rooms, multifamily residential plumbing, and institutional facilities. It is particularly well suited for maintenance and repair applications where wet-line connections must be made without fully draining the system. Licensed plumbers and pipefitters are the typical installers.

Key Features

• Zero-lead copper construction meets lead-free potable water requirements
• Cold-press joining eliminates open flame and soldering on the job site
• Connections are completed in four to seven seconds per joint using a compatible press tool
• Viega Smart Connect feature reveals unpressed connections during pressure testing, preventing missed joints
• Rated for wet-line connections, reducing system downtime during repairs
• Heavier wall thickness than Type K copper for added durability

Compatibility

Designed for use with the Viega ProPress system using 2-inch press-end tooling and jaw sets compatible with the ProPress fitting series.

Installation Notes

Installation requires a Viega-compatible press tool with the correct 2-inch jaw or ring set. Shut off and relieve pressure from the line before cutting and fitting. Press connections must be made in accordance with the fitting manufacturer guidelines and local plumbing code, typically referencing IPC or UPC standards. Inspect each fitting for the Smart Connect indicator after pressure testing to confirm all joints are fully pressed.
