Viega 78087 Propress Copper Reducer 1 X 3/4 Inch

Product Description

The VIEGA 78087 is a ProPress copper reducer fitting designed for professional plumbing installations. It connects a 1-inch line to a 3/4-inch line using a FTG x Press configuration, eliminating the need for soldering at the press end. The Smart Connect feature allows installers to visually verify whether a fitting has been pressed, reducing the risk of unpressed joints in the system. At 0.144 pounds, this compact fitting is suited for tight spaces and high-volume rough-in work. Licensed plumbers and pipefitters rely on this fitting for fast, reliable transitions in copper piping systems.

This reducer is intended for plumbing applications where copper pipe sizing changes within a distribution system. It is commonly installed during new construction and remodel work wherever a 1-inch supply line steps down to a 3/4-inch branch line. The press-style connection is compatible with standard ProPress tooling, making it a practical choice for commercial and residential plumbing projects where open-flame work is restricted or undesirable.

Key Features

• Smart Connect technology allows visual confirmation that the fitting has been properly pressed
• FTG x Press connection eliminates soldering on the press end
• Copper construction provides corrosion resistance for potable water and hydronic systems
• 1 inch x 3/4 inch sizing covers common supply-to-branch transitions
• Lightweight at 0.144 pounds, suited for high-density installations

Compatibility

Designed as an OEM-style press fitting for use with standard copper ProPress tooling in residential and commercial plumbing systems where 1-inch to 3/4-inch copper pipe transitions are required.

Installation Notes

Installation should be performed by a licensed plumber following applicable IPC or local plumbing code requirements. Shut off the water supply and relieve pressure in the line before fitting installation. Use only jaw sets rated for copper ProPress fittings with a compatible press tool. Do not reuse a fitting that has been pressed onto a pipe.
