Viega ProPress 3/4" - 45° Copper Elbow - Street/Press Connection - Smart Connect Technology

The Viega ProPress 3/4" - 45° Copper Elbow with Street/Press Connection and Smart Connect Technology is a professional-grade plumbing fitting designed for reliable water system installations in cabins, remote shelters, and field operations where dependable infrastructure matters. Built for contractors and homeowners who demand durability in demanding conditions, this copper elbow connects branch lines at precise 45-degree angles while maintaining watertight seals under varying pressure and temperature cycles—critical for systems exposed to seasonal stress and freeze-thaw cycles common in backcountry or rural settings.

This fitting uses ASTM B88 copper tubing and incorporates Viega's Smart Connect Technology, which enables visual and audible feedback during installation to confirm proper seating and connection integrity. The street/press hybrid design allows both press connection on the primary port and a street (recessed) connection on the branch, eliminating the need for additional adapters in tight spaces. The EPDM sealing element provides chemical resistance and long-term reliability across a wide temperature range, ensuring years of leak-free service without maintenance or rework—especially valuable when access to repair sites is difficult or costly.

This elbow is ideal for installers working on potable water systems, hydronic heating loops, and standalone off-grid water infrastructure where code compliance and longevity are non-negotiable. Its compact 1 x 1 x 3 inch profile and lightweight 0.15 lbs construction make it easy to carry into remote job sites, while the 3/4" bore supports moderate to high flow demands typical of residential or small commercial applications. Compatibility with standard ASTM B88 copper tubing means seamless integration into existing systems or new installations using conventional press tools and techniques.
