Viega 20873 Press-Fit Copper Tee

The Viega 20873 is a copper press-fit tee designed for potable water systems. It connects two 4 in press-fit ends with a 3/4 in FNPT branch, providing a secure adapter junction. The fitting includes a centre stop dimple for proper tube insertion depth. An EPDM O-ring seals each press connection.

Suited for 4 in copper mains

Plumbers running a 4 in copper main who need a 3/4 in female threaded outlet will find this tee fits the requirement. The press-fit ends eliminate the need for soldering on the main line. Installers who need all three ports as press-fit or who require a different branch size should look at other fittings.

Rated for 200 psi operating pressure

The fitting withstands a maximum operating pressure of 200 psi in potable water service. The EPDM seals maintain integrity at this pressure when the press joints are made correctly. Systems exceeding 200 psi or using incompatible fluids are beyond the rated capacity of this tee.

Questions about this item

What copper tube sizes must already be installed for the 4 in press-fit ends to connect?

Both press-fit ends require 4 in copper tube size to make a proper connection.

Will the 3/4 in FNPT branch accept existing 3/4 in threaded pipe without an adapter?

Yes, the branch is a 3/4 in FNPT thread that mates directly with 3/4 in male pipe threads.

How can I confirm the joint is holding pressure after pressing the 4 in connections?

Pressurize the system up to the 200 psi maximum operating pressure and verify no leaks at the press-fit joints and threaded branch.
