Description
CarbonPress® Carbon Steel Press Couplings without Stop
CarbonPress® Carbon Steel Press Couplings without Stop provide a straight connection between two sections of compatible carbon steel pipe while allowing the fitting to slide along the pipe during installation. The no-stop design is especially useful for repair work, cut-ins, and installations where the coupling must be positioned after both pipe ends are aligned.
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 coupling 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.
Coupling without Stop Design
Unlike a coupling with an internal pipe stop, this configuration allows the fitting to slide completely over the pipe before being positioned across the joint. This makes it useful for repair work, replacement sections, and piping modifications where movement of the existing pipe is limited.
Leak Before Press Technology
CarbonPress® fittings incorporate Leak Before Press (LBP) Technology, helping identify connections that have not been properly pressed during system testing.

Selection & Application Guidance
- Select the coupling size to match both sections of carbon steel pipe.
- 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.
- Mark the required insertion depth on both pipe ends before final positioning because the fitting has no internal stop.
- Center the coupling over the joint before pressing both ends.
- 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.

Frequently Asked Questions
What is a CarbonPress® coupling without stop used for?
It is used to join two equal-size sections of compatible carbon steel pipe and is especially useful for repairs, cut-ins, and installations where the coupling needs to slide over the pipe.
How is a coupling without stop different from a coupling with stop?
A coupling with stop has an internal pipe stop that limits insertion depth. A coupling without stop can slide along the pipe, allowing it to be positioned over an existing joint or repair section.
Why would I use a coupling without stop?
The no-stop design is useful when existing pipe cannot be moved enough to install a standard coupling or when the fitting must slide completely onto one pipe before being centered over the joint.
What pipe can CarbonPress® fittings be used with?
CarbonPress® is suitable for black iron, epoxy-coated, and galvanized Schedule 10 through Schedule 40 carbon steel pipe.
What sizes does the CarbonPress® system cover?
The CarbonPress® system covers sizes from 1/2" through 2".
What is the EPDM temperature range?
The EPDM temperature range is -40°F to 300°F (-40°C to 148°C).
What is the HNBR temperature range?
The HNBR temperature range is -40°F to 200°F (-40°C to 93°C).
Do CarbonPress® fittings have Leak Before Press technology?
Yes. CarbonPress® fittings incorporate Leak Before Press (LBP) Technology.
What press tools can be used with CarbonPress®?
CarbonPress® fittings can be pressed with Milwaukee or RIDGID tools and the associated jaws or rings for carbon steel applications.
What warranty is provided?
CarbonPress® fittings have a 15-year limited warranty.
