Viega 77637 45 Degree Street Elbow 1/2 Inch Press Copper

Product Description

The VIEGA 77637 is a 45-degree street elbow designed for press-fit copper piping systems. It connects a fitting end to a press end, allowing a direction change of 45 degrees without requiring soldering or open flame. The 1/2-inch nominal size fits standard residential and light commercial copper pipe. Licensed plumbers and pipefitters install this fitting as part of ProPress-style press-fit systems, where speed and flame-free installation are priorities in occupied or fire-sensitive spaces.

This fitting is used in residential and commercial plumbing applications where copper press systems are specified. It suits new construction and retrofit work alike, including domestic water supply lines and hydronic piping. The street configuration means one end accepts a standard press fitting directly, reducing the need for additional couplings in tight spaces or when transitioning between fitting runs.

Key Features

• 45-degree offset for directional changes in copper press-fit piping systems
• Street configuration with one fitting end and one press end for direct connection
• 1/2-inch nominal size for standard residential and light commercial pipe runs
• Copper construction for corrosion resistance and compatibility with potable water systems
• Flame-free press installation eliminates the need for soldering in sensitive environments

Compatibility

Designed as an OEM-style replacement and standard fitting for 1/2-inch nominal copper press-fit plumbing systems using ProPress-compatible press tooling.

Installation Notes

Installation requires a press tool compatible with ProPress jaws and rings rated for the fitting size. Shut off and depressurize the water supply before beginning work. Ensure pipe ends are clean, deburred, and fully inserted to the depth mark before pressing. All press-fit copper installations should comply with applicable local plumbing codes and ASTM standards for copper tube and fittings.
