Viega 79245 Press X Mnpt Pipe Adapter 1 Inch

Product Description

The VIEGA 79245 is a bronze pipe adapter designed to transition between a press-style connection and a male NPT threaded end. It is a key fitting for plumbing systems where press-fit copper or compatible tubing meets threaded pipe connections. At 1 inch nominal size, this adapter handles typical residential and light commercial water distribution applications. A licensed plumber or pipefitter installs this fitting using a press tool, eliminating the need for open flame soldering at the transition point. The bronze construction provides corrosion resistance and durability suited to wet service environments.

This adapter is used in potable water distribution, hydronic heating systems, and general plumbing installations where a press-end supply line must connect to a male NPT threaded component such as a valve, manifold, or equipment inlet. It is well-suited for retrofit work and new construction where a no-solder press connection is preferred or required. The MNPT end threads directly onto a compatible female-threaded fitting or port following standard NPT taper thread practice.

Key Features

• Press x MNPT end configuration for direct press-to-thread transitions
• 1 inch nominal size for standard water distribution piping
• Bronze construction for corrosion resistance in wet service
• No-flame installation at the press end reduces fire risk on the job
• NPT taper thread end compatible with standard female-threaded fittings and equipment ports

Compatibility

Designed as an OEM-style press fitting for use in press-fit copper and compatible tubing systems at 1 inch nominal pipe size with standard NPT threaded components.

Installation Notes

Installation of the press end requires a calibrated press tool approved for the fitting size and jaw type. A licensed plumber should perform installation in accordance with local plumbing codes and IPC guidelines. Shut off and depressurize the water supply before making any connections. The MNPT end should be wrapped with PTFE tape or pipe thread sealant and threaded to a snug fit without overtightening to avoid cracking the fitting body.
