Viega VIEGRED3412 Propress Pipe Reducer 3/4 X 1/2 Inch Press Copper Reducing Coupling

Product Description

The Viega VIEGRED3412 ProPress Pipe Reducer is a press-style copper reducing coupling designed for professional plumbing and mechanical systems. This fitting connects 3/4 inch nominal pipe to 1/2 inch nominal pipe using a reliable press connection method that eliminates the need for open flame, soldering, or flux. Plumbers, pipefitters, and mechanical contractors rely on press fittings like this one to speed up installation time and reduce jobsite risk. The ProPress system is widely used in residential, commercial, and light industrial plumbing applications where efficiency and leak-free connections matter.

This reducer measures 2.07 inches in length and is rated for working pressures up to 200 psi. It handles a temperature range of 0 to 250 degrees Fahrenheit, making it suitable for hot and cold domestic water lines, hydronic heating systems, and other closed-loop piping applications. The copper construction provides excellent corrosion resistance and long-term durability in potable water systems. Copper press fittings meet or exceed industry standards for plumbing systems and are compatible with standard copper tubing of the corresponding nominal sizes.

The press-end style means installation is fast and consistent. A compatible press tool with the correct jaw size crimps the fitting onto the pipe in seconds, creating a permanent, watertight seal without heat. This makes the Viega VIEGRED3412 an ideal choice for tight spaces, retrofits, and new construction alike. Reducing couplings like this one are essential whenever a pipe run transitions from a larger diameter to a smaller diameter, such as running a branch line off a main supply line. Keeping these fittings on hand reduces downtime on the job and keeps plumbing projects moving forward.

• Press-style connection for fast, flame-free installation using a standard press tool
• Rated to 200 psi and 0 to 250 degrees Fahrenheit for hot and cold water applications
• Copper construction provides corrosion resistance and compatibility with potable water systems
