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

The Viega ProPress 1" Copper Coupling without Stop featuring Double Press Connection and Smart Connect Technology is a press-fit coupling designed for ASTM B88 copper tubing installations. This product eliminates the need for traditional soldering or threading, enabling faster, more reliable connections in residential and commercial plumbing applications. The press connection method provides consistent joints without flame, flux, or cleanup.

The coupling is manufactured from copper material with EPDM sealing elements that create a watertight seal when properly pressed. The 1" size accommodates standard copper tubing diameters and integrates with Viega's press system tooling. Smart Connect Technology allows visual confirmation of connection integrity, reducing the risk of incomplete or defective joints on the job site. Without a stop design offers flexibility in configurations where end constraints require a streamlined profile.

This coupling is ideal for plumbers, HVAC technicians, and contractors working on new construction, renovation, and service projects where speed and reliability are critical. The press-fit system eliminates common soldering problems—cold joints, flux residue, and water quality issues—while maintaining code compliance. Installation requires only a compatible press tool, making it suitable for both skilled trades and trained installation crews.

Press couplings have become the standard in modern plumbing systems for their repeatability and speed. Viega's ProPress line is recognized across the industry for consistency and durability. The 1" coupling size addresses mid-range distribution lines in residential systems and smaller commercial applications, making it a versatile component for general plumbing inventory.
