Viega 49343 Press Coupling 3/4 X 1/2 Inch Polymer

Product Description

The VIEGA 49343 is a reducing press coupling designed for use in PureFlow PEX piping systems. It connects a 3/4-inch nominal line to a 1/2-inch nominal line using a press end connection style, eliminating the need for open flame or soldering during installation. The polymer construction resists corrosion and scale buildup, making it well suited for potable water distribution and hydronic applications. Licensed plumbers and pipefitters install this fitting as part of new construction or retrofit work where reducing a line size is required within a PEX distribution system.

This coupling is intended for residential and light commercial plumbing installations that use PureFlow PEX tubing. It is a domestically produced fitting and serves as a reducing connector wherever a 3/4-inch supply line must transition to a 1/2-inch branch line. Typical applications include branch takeoffs in water distribution manifold systems, under-sink supply runs, and fixture drops in residential construction.

Key Features

• Press end connection style requires no flame, solder, or adhesive for installation
• Polymer body construction resists corrosion and is compatible with potable water service
• Reducing configuration joins a 3/4-inch nominal inlet to a 1/2-inch nominal outlet
• Domestically produced fitting for use in PureFlow PEX piping systems
• Compact coupling profile simplifies installation in tight spaces

Compatibility

Designed as an OEM-style replacement and new-installation fitting for VIEGA PureFlow PEX press piping systems with 3/4-inch to 1/2-inch reducing connections.

Installation Notes

Installation should be performed by a licensed plumber following applicable local plumbing codes and IPC guidelines. Shut off the water supply and depressurize the line before making any connections. A manufacturer-approved press tool with the correct jaw size for each end is required to achieve a proper, leak-free press connection. Do not attempt to press the fitting with an incompatible tool or undersized jaw, as this will result in an incomplete seal.
