Viega 77042 Propress 90 Degree Short Radius Elbow 2 in

Product Description

The VIEGA 77042 is a ProPress 90-degree short radius elbow fitting designed for flameless, press-type connections on standard copper tubing. Rated to 200 psi with a temperature range of 0 to 250 degrees F, it joins 2-inch copper pipe using a press-tool connection on both ends, eliminating the need for flux, solder, or open flame. The fitting includes the Viega Smart Connect feature, which allows technicians to identify unpressed connections before pressure testing. Licensed plumbers and pipefitters install this fitting using compatible copper press tools, sold separately.

This fitting is suited for residential and commercial plumbing applications where flameless joining is required or preferred. Common use cases include potable water distribution, hydronic systems, and fire sprinkler installations where NFPA 13, 13D, and 13R compliance is required. Its short radius profile makes it practical in tight spaces and congested mechanical rooms. The 2-inch press-by-press configuration works with standard Type K, L, or M copper tubing.
