Viega 77057 90 Degree Street Elbow 1 Inch Copper

Product Description

The VIEGA 77057 is a 90-degree street elbow designed for use in copper press-fit piping systems. It features a fitting-end inlet and a press end outlet, allowing it to connect directly to standard copper tube without soldering or open flame. At 1 inch nominal size, this elbow redirects flow at a right angle within tight mechanical, plumbing, and HVAC piping runs. Licensed plumbers and pipefitters install this fitting as part of press-connection systems, where speed and consistency are critical. The press-end design creates a secure, leak-tested joint using a standard pressing tool equipped with the appropriate jaw set.

This elbow is suited for residential and light commercial plumbing, hydronic heating, and mechanical piping applications where copper press systems are specified. The street configuration allows direct insertion into another fitting socket, eliminating the need for a short nipple or additional coupling. It is appropriate for potable water, heating, and cooling distribution lines where copper press systems are code-accepted.

Key Features

• 90-degree street elbow configuration for direct fitting-to-fitting connections
• 1 inch nominal size fits standard copper tubing and press fittings
• Fitting x press end style for flameless installation with a press tool
• Copper construction for corrosion resistance in wet service environments
• Compatible with standard press-fit tooling used in professional plumbing installations

Compatibility

Designed as an OEM-style press-fit replacement and new-installation fitting for 1 inch nominal copper press piping systems.

Installation Notes

Installation requires a calibrated pressing tool with the correct jaw size for 1 inch press fittings. Shut off and depressurize the supply line before cutting or fitting. Verify the pipe end is cut square, deburred, and fully inserted to the stop mark before pressing. All press connections must be inspected per the applicable plumbing code, including IPC and local amendments, before the system is pressurized.
