The Viega VIEGADCMIP3 is a ProPress XL-C pipe adapter designed for 3 inch nominal pipe connections. It features a Press x MNPT end style, meaning one end connects using the Viega press system and the other end uses a male NPT threaded connection. This adapter is made from copper and is built to handle demanding plumbing and mechanical systems in commercial and industrial settings.
The ProPress XL-C system is a widely used press-fit connection method that eliminates the need for soldering, open flame, or flux. Plumbers and pipefitters rely on it to speed up installation, reduce labor time, and maintain a safer work environment on job sites. The press connection creates a reliable, leak-free seal using a compatible press tool with the correct jaw size for 3 inch fittings.
This adapter is rated for pressures up to 200 psi and is suitable for operating temperatures ranging from 0 to 250 degrees Fahrenheit. That range covers a wide variety of hydronic heating systems, domestic hot and cold water distribution, and mechanical room piping. The male NPT threaded end allows direct connection to threaded valves, flanges, equipment ports, and other threaded fittings, making this adapter a versatile transition piece in many plumbing configurations.
Trade professionals working on large-diameter copper piping systems will find this fitting essential when transitioning between press-fit copper pipe and threaded connections. It is commonly used in commercial plumbing, HVAC hydronic loops, and industrial fluid systems where both speed and reliability are critical. Proper installation requires a Viega-approved press tool and the correct jaw or ring set for 3 inch press connections.
The Viega VIEGADCMIP3 ProPress XL-C copper pipe adapter delivers a fast, flame-free press connection on one end and a standard male NPT thread on the other, making it a reliable transition fitting for 3 inch commercial plumbing and mechanical systems rated up to 200 psi.
