Viega 79330 Pipe Adapter 1 Inch Press X Fnpt Bronze

Product Description

The VIEGA 79330 is a bronze pipe adapter designed for transitioning between press-fit and female NPT threaded connections in copper piping systems. The 1-inch nominal size fits standard residential and commercial plumbing and hydronic heating applications. This adapter features a press end on one side and a female NPT (FNPT) threaded end on the other, allowing a licensed plumber to connect press-tool-compatible tubing directly to threaded pipe, valves, or equipment without soldering. Bronze construction provides corrosion resistance and long service life in potable water and heating system environments.

This adapter is suited for residential and light commercial plumbing installations where copper press systems interface with threaded components such as valves, gauges, pumps, or equipment inlets. It is commonly installed by licensed plumbers during new construction, retrofit work, or system upgrades where a no-solder press connection is preferred for speed, code compliance, or torch-restricted job sites.

Key Features

• Press x FNPT end style allows direct transition from press-fit copper to female threaded connections
• 1-inch nominal size fits standard copper tubing and threaded pipe in common plumbing applications
• Bronze construction offers corrosion resistance suitable for potable water and hydronic systems
• No-solder press connection reduces installation time and eliminates open-flame requirements on restricted job sites

Compatibility

Designed as an OEM-style press fitting for use in 1-inch nominal copper press piping systems where a transition to female NPT threaded connections is required.

Installation Notes

Installation of press fittings requires an approved press tool with the correct jaw size for the fitting diameter. Shut off and depressurize the water or hydronic system before installing or removing any fitting. Verify that the pipe end is clean, round, and properly deburred before pressing. Follow all applicable local plumbing codes and manufacturer pressing instructions to ensure a leak-free joint.
