Description
CarbonPress® Carbon Steel Press Reducing Coupling
CarbonPress® Carbon Steel Press Reducing Couplings provide a straight transition between two different carbon steel pipe sizes without welding or threading. The reducing design allows a larger press-connected pipe run to transition directly to a smaller pipe size in a compact fitting.
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 each end of 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 Coupling Design
The reducing coupling combines two different-size press connections in one fitting, allowing the piping system to transition from a larger nominal pipe size to a smaller nominal pipe size while maintaining a straight-line configuration.
Leak Before Press Technology
CarbonPress® fittings incorporate Leak Before Press (LBP) Technology, helping identify connections that have not been properly pressed during system testing.
EPDM & HNBR Seal Options
- EPDM: -40°F to 300°F (-40°C to 148°C)
- HNBR: -40°F to 200°F (-40°C to 93°C)
Select the sealing element appropriate for the intended system and application.
Pipe Compatibility
CarbonPress® is suitable for use with:
- Black iron carbon steel pipe

Selection & Application Guidance
- Select both the larger and smaller press sizes required for the piping transition.
- Verify both pipe sizes are within the supported CarbonPress® system range.
- Verify the pipe is within the supported Schedule 10 through Schedule 40 range.
- Confirm whether EPDM or HNBR is appropriate for the intended application.
- Verify temperature and media compatibility before installation.
- Use compatible Milwaukee or RIDGID press tools with the appropriate carbon steel jaws or rings.
- Follow the applicable CarbonPress® installation requirements when preparing and pressing each connection.
