Description
CarbonPress® Carbon Steel Press Reducing Tee
CarbonPress® Carbon Steel Press Reducing Tees provide a three-way branch connection with a reduced branch size for compatible carbon steel piping systems. The reducing tee design allows the main run to continue through the fitting while transitioning to a smaller branch connection.
CarbonPress® is a 1/2" through 2" carbon steel press fitting system suitable for use with black iron, epoxy-coated, and galvanized Schedule 10 through Schedule 40 carbon steel pipe. When pressed, an internal grab ring grips the outside diameter of the pipe while an elastomeric sealing element creates a leak-tight seal.
CarbonPress® fittings can be installed using Milwaukee or RIDGID press tools with the associated jaws or rings designed for carbon steel applications.

CarbonPress® Connection Technology
When the fitting is pressed, a grab ring deforms and its sharp edges grip the outside diameter of the pipe, securing the fitting axially and helping prevent movement.
At the same time, an elastomeric sealing element impinges on the pipe to create a leak-tight connection.
Reducing Tee Design
The reducing tee provides three press connection points, with the branch connection sized smaller than the main run. This allows the piping system to continue through the tee while creating a reduced 90° branch from the main line.
Leak Before Press Technology
CarbonPress® fittings incorporate Leak Before Press (LBP) Technology, helping identify connections that have not been properly pressed during system testing.
