Viega ProPress 1-1/4" Copper Coupling w/o Stop - Double Press Connection - Smart Connect Technology

The Viega ProPress 1-1/4" Copper Coupling w/o Stop with Double Press Connection and Smart Connect Technology is engineered for plumbing professionals and contractors who demand reliability in residential and commercial water distribution systems. This coupling eliminates the need for solder and flux, delivering faster installation times while maintaining code-compliant, leak-free connections on ASTM B88 copper tubing. The absence of a stop collar makes it ideal for applications requiring a full-flow interior bore without obstruction.

ProPress technology utilizes a specialized press tool to create a permanent, cold-welded joint that exceeds solder in shear and tensile strength—critical for high-pressure or vibration-prone installations. The Smart Connect Technology provides tactile and audible feedback during pressing, ensuring every connection meets Viega's exacting standards without guesswork. Constructed from premium copper, the 1-1/4" coupling features an EPDM sealing element that withstands potable water conditions and performs reliably across standard operating pressures, eliminating common failure points associated with traditional soldered fittings.

Installers benefit from reduced labor costs, faster job completion, and zero risk of fire hazard during installation—a decisive advantage in occupied buildings and retrofit work. The double press connection design accommodates 1-1/4" copper lines on both ends, making it suitable for supply lines, distribution mains, and circulation loops in residential heating systems, commercial HVAC, and potable water applications. Compact and lightweight at just 0.2 lbs, this coupling integrates seamlessly into tight spaces while maintaining full system integrity for decades.
