The Viega VIEGTRED1121121 is a ProPress copper pipe tee fitting designed for professional plumbing and mechanical piping systems. This tee fitting features a 1-1/2 inch by 1-1/2 inch by 1 inch nominal size configuration, making it a reducing tee that allows a branch connection of 1 inch to run off a 1-1/2 inch main line. The overall length of the fitting is 4.34 inches, providing a compact profile that fits well in tight mechanical spaces. Plumbers, pipefitters, and mechanical contractors rely on press-style copper fittings like this one to speed up installation time compared to traditional soldered or brazed connections. The press end style means no open flame is required on the job site, which reduces fire risk and eliminates the need for hot work permits in many commercial and residential applications. Each end of the fitting uses a press connection that creates a permanent, leak-tight seal using a calibrated pressing tool. This method is widely accepted in potable water, hydronic heating, cooling, and fire suppression systems. Copper construction provides excellent corrosion resistance and long service life, even in demanding water quality conditions. The reducing tee design allows contractors to branch off a smaller 1 inch line from a larger 1-1/2 inch run without adding extra reducers or couplings, saving both labor and materials. This fitting is compatible with standard copper tubing and works with approved Viega ProPress pressing tools. It is suitable for use in new construction and retrofit plumbing projects. Trade professionals trust ProPress fittings to meet code requirements and hold up under pressure in commercial, industrial, and residential plumbing systems.
The Viega VIEGTRED1121121 ProPress copper reducing tee delivers fast, flame-free press connections in a 1-1/2 x 1-1/2 x 1 inch configuration, making it a reliable choice for professional plumbing and mechanical piping installations.
