Viega 49357 Pureflow Reducing Coupling 1-1/4 X 1 in Pex Press

Product Description

The VIEGA 49357 is a PureFlow reducing coupling designed for PEX press piping systems. Model V5615, it transitions from a 1-1/4 inch nominal pipe to a 1 inch nominal pipe using a press-style end connection. The body is constructed from polymer, making it lightweight and corrosion-resistant. This fitting is installed by licensed plumbers working on residential and light commercial PEX distribution systems where a pipe size reduction is required within the supply line. The press end style eliminates open flame, speeding up installation in tight or fire-sensitive spaces.

The 49357 is suited for PEX press installations in potable water supply and hydronic distribution applications. It is typically used where a main distribution line steps down to a branch line, such as transitioning from a trunk line to an individual fixture or zone supply. The polymer construction makes it well-suited for installations where metallic fittings may be subject to corrosive water conditions. Plumbing contractors and mechanical contractors working with PEX press tooling will find this fitting compatible with standard PureFlow press sleeve installation procedures.

Key Features

• Reduces from 1-1/4 inch nominal to 1 inch nominal in a single fitting
• PEX press end style — no soldering, brazing, or open flame required
• Polymer body construction offers corrosion resistance and light weight
• PureFlow product line engineered for PEX press distribution systems
• Streamlines branch takeoffs and pipe size transitions in supply piping

Compatibility

Designed as an OEM-style fitting for PEX press piping systems using the VIEGA PureFlow press sleeve method. Specific system and tool compatibility should be verified against VIEGA PureFlow installation requirements prior to installation.

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the applicable IPC or UPC requirements. Depressurize and drain the piping system fully before cutting in the fitting. A VIEGA-compatible PEX press tool and the correct press sleeve size are required — do not substitute incompatible press tools, as an improper press can result in a failed joint. Inspect the PEX tubing ends for squareness and remove any burrs before inserting into the fitting.
