Viega ProPress 1-1/2" Copper Coupling w/o Stop - Double Press Connection - Smart Connect Technology

The Viega ProPress 1-1/2" Copper Coupling without Stop featuring Double Press Connection and Smart Connect Technology is a high-performance plumbing coupling engineered for rapid, reliable press-fit installations in commercial and residential piping systems. This coupling is specifically designed for use with ASTM B88 copper tubing, meeting industry standards for durability and leak-free connections in both water supply and hydronic heating applications.

The ProPress coupling utilizes a full-copper body with EPDM sealing elements that provide reliable long-term performance across a wide temperature range. The double press connection design—requiring compression on both sides of the coupling—ensures consistent, verifiable connections without reliance on solder, flux, or traditional threaded fittings. Smart Connect Technology integration allows for tool compatibility with Viega's press systems, enabling faster connection cycles on the job site while reducing the skill variability that can affect traditional soldered or threaded assemblies. The absence of an internal stop simplifies installation in tight spaces where standard couplings cannot fit.

Contractors and service technicians choose the ProPress coupling for retrofit work, new construction, and maintenance applications where code compliance and inspection-ready connections are essential. The 1-1/2" size accommodates mid-range distribution lines in residential homes, commercial buildings, and industrial facilities. Press-fit technology eliminates water quality concerns associated with solder flux and reduces on-site fire hazards, making it the preferred choice for properties where flame-free installation is required or preferred. This coupling is ideal for plumbers, mechanical contractors, and facility managers seeking faster, cleaner, and more repeatable connection methods.
