Description
CarbonPress® Carbon Steel Press Cap
CarbonPress® Carbon Steel Press Caps provide a secure end closure for compatible carbon steel piping systems without welding or threading. The CarbonPress® system is designed for 1/2" through 2" black iron, epoxy-coated, and galvanized Schedule 10 through Schedule 40 carbon steel pipe.
When the fitting is pressed, an internal grab ring deforms so its sharp edges grip the outside diameter of the pipe, securing the fitting axially and helping prevent movement. At the same time, the elastomeric sealing element impinges on the pipe to create 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 cap 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 end connection.
Press Cap Design
The cap configuration is designed to close the end of a compatible carbon steel pipe run. It provides a compact press-connected termination without requiring a threaded plug, welded cap, or additional adapter fitting.
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.
