Viega 20678 4 Inch Copper 45 Degree Street Elbow

Product Description

The VIEGA 20678 is a 45-degree street elbow designed for press-connect copper piping systems. It features a fitting end on one side and a press end on the other, allowing it to connect directly into an existing fitting socket without the need for a coupling. Built from copper, this elbow is suited for use in commercial and residential plumbing, hydronic heating, and mechanical piping installations where a 45-degree change in direction is required at a 4-inch nominal pipe size. Licensed plumbers and pipefitters are the primary installers of this component.

This elbow is used in 4-inch nominal copper press piping systems. Its street configuration — fitting-by-press end style — makes it particularly useful in tight spaces or when transitioning directly out of a valve, fitting, or other component that accepts a press connection. It is well suited for commercial mechanical rooms, large-scale plumbing riser work, and industrial hydronic systems where press-fit tooling is already in use on the jobsite.

Key Features

• 45-degree offset geometry for directional changes in press copper piping runs
• Street configuration: fitting end on one side, press end on the other — eliminates the need for an additional coupling
• 4-inch nominal size handles large-diameter pipe runs common in commercial applications
• Copper construction provides corrosion resistance and compatibility with potable water systems
• Press-connect end style speeds installation and eliminates open-flame soldering on the press side

Compatibility

Designed as an OEM-style press-connect fitting for use in 4-inch nominal copper press piping systems where a 45-degree street elbow configuration is required.

Installation Notes

Installation should be performed by a licensed plumber or pipefitter using a press tool approved for copper press fittings at this pipe size. Depressurize and drain the piping system fully before making any connections or modifications. Verify that the pipe end is clean, round, and deburred to the fitting manufacturer's requirements before pressing. Follow all applicable local plumbing codes and ASME B16.18 or B16.22 standards as required by the authority having jurisdiction.
