Viega 79550 90 Degree Press X Fnpt Bronze Elbow 1 in

Product Description

The VIEGA 79550 is a 90-degree pipe elbow designed for use in press-fit piping systems. It connects a 1-inch nominal press end to a female NPT (FNPT) threaded end, allowing transitions between press-fit copper tubing and threaded pipe connections. Constructed from bronze, this elbow delivers corrosion resistance suitable for potable water, hydronic heating, and commercial plumbing applications. Licensed plumbers and pipefitters install this fitting as part of press-system assemblies, eliminating the need for open-flame soldering at the transition point.

This elbow is suited for residential and light commercial plumbing installations where a direction change and a press-to-thread transition are needed in the same fitting. It is commonly installed in hydronic heating loops, domestic hot and cold water distribution lines, and mechanical room piping where threaded equipment connections meet press-fit copper distribution. The 1-inch nominal size fits standard copper tube of the same nominal diameter.

Key Features

• 90-degree elbow geometry for direction changes in tight spaces
• Press x FNPT end style allows direct connection from press-fit copper to female threaded fittings or equipment ports
• Bronze construction provides corrosion resistance in wet plumbing and hydronic environments
• 1-inch nominal size fits standard 1-inch copper tubing on the press end
• Press connection eliminates open-flame soldering, reducing fire risk and labor time

Compatibility

Designed as an OEM-style press-fit fitting for use in 1-inch nominal press-system copper piping assemblies with a female NPT threaded outlet.

Installation Notes

Installation should be performed by a licensed plumber familiar with press-fit tooling and local plumbing codes. Shut off and depressurize the water supply and verify the pipe is dry before pressing. Use only a press tool and jaw set rated and sized for 1-inch press fittings to ensure a leak-free connection. The FNPT end requires compatible male-threaded pipe or fittings and appropriate thread sealant per local code requirements.
