Viega 77330 90 Deg Reducing Elbow 1x3/4 in Press Copper

Product Description

The VIEGA 77330 is a 90-degree reducing elbow designed for press-style copper piping systems. It connects a 1-inch nominal line to a 3/4-inch nominal line in a single fitting, eliminating the need for a separate reducer and elbow. The press end style allows tool-actuated cold-press connections without open flame, making it well suited for installations where torch work is restricted or impractical. Licensed plumbers and pipefitters are the primary installers of this fitting in new construction and retrofit applications.

This fitting is used in residential and light commercial plumbing systems where copper press technology is specified. Typical applications include domestic water distribution, radiant heating supply and return lines, and hydronic systems that require a direction change with a simultaneous size reduction. The press end connection style requires a compatible press tool and jaws sized for the respective nominal pipe diameters at each end.

Key Features

• 90-degree elbow with integrated reduction from 1 inch to 3/4 inch nominal in one fitting
• Press end connection style eliminates open-flame soldering at the joint
• Copper construction for compatibility with standard copper tube systems
• Compact form factor reduces fitting count and potential leak points in tight spaces
• Suitable for potable water and hydronic piping applications

Compatibility

Designed as an OEM-style press fitting for use with standard copper tubing in press-fit plumbing systems requiring a 1-inch to 3/4-inch nominal 90-degree reducing connection.

Installation Notes

Installation must be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC requirements. Shut off water supply and depressurize the line before installing or servicing any press fitting. A compatible press tool with correctly sized jaws for both the 1-inch and 3/4-inch ends is required to achieve a proper seal. Do not use an open flame or solder on press-style fittings.
