Viega 78067 Propress Copper Coupling with Stop 1-1/2 in

Product Description

The VIEGA 78067 is a zero-lead copper coupling with stop, sized at 1-1/2 inches P x P, designed for press-fit joining of copper pipe in plumbing systems. The fitting uses a press connection that completes in four to seven seconds, eliminating the need for soldering, flux, or threading equipment. The stop feature ensures consistent insertion depth, promoting a reliable, watertight seal every time. Constructed from copper and built heavier than Type K copper pipe, the 78067 is suited for professional plumbing installations where long-term reliability and code compliance are required. Licensed plumbers and pipefitters are the primary installers of this fitting.

The VIEGA 78067 ProPress coupling is adaptable for residential, commercial, and industrial plumbing applications, including new construction and retrofit work. Because press connections can be made on wet lines, this fitting is especially effective for maintenance and repair scenarios where draining the system completely is not practical. The press-fit design keeps projects on schedule by reducing installation time compared to traditional soldered copper fittings.

Key Features

• Zero-lead copper construction meets North American plumbing codes for potable water systems
• Press connection completes in four to seven seconds for rapid installation
• Integral stop ensures consistent pipe insertion depth and a reliable seal
• Compatible with wet-line connections, reducing downtime during maintenance and repair
• Eliminates soldering, flux, threading, and associated equipment from the workflow
• Heavier wall construction than Type K copper for added durability

Compatibility

Designed as an OEM-style ProPress press-fit replacement fitting for 1-1/2 inch copper pipe systems using P x P (press by press) end connections in residential, commercial, or industrial plumbing applications.

Installation Notes

Installation requires a compatible ProPress pressing tool and appropriate press jaws sized for 1-1/2 inch fittings. Shut off supply pressure and relieve system pressure before beginning work where possible, though the fitting supports wet-line pressing when full shutoff is not feasible. Follow all applicable local plumbing codes, IPC requirements, and manufacturer pressing tool guidelines. Verify the connection is fully pressed before restoring system pressure.
