Carrier EC39EZ067 Valve Core

Carrier EC39EZ067 is a Schrader valve core used on refrigerant access ports throughout Carrier HVAC/R equipment. It provides the internal seal that retains refrigerant charge while allowing gauge or hose connection during service, charging, or recovery operations. This OEM component is suited for both residential and commercial applications, covering split systems, heat pumps, package units, mini-splits, and chillers. It is a non-hazmat, DIY-friendly part that any technician can swap without specialized tools. As a direct OEM replacement, this valve core matches Carrier equipment specifications for proper seat sealing and pressure retention, reducing the risk of refrigerant leaks from worn or damaged cores. It is compatible with Carrier systems across the listed equipment types, making it a straightforward stock item for routine maintenance, leak repair, or service port rebuilds. Installation involves removing the depleted core with a valve core tool and threading in the replacement, then verifying a proper seal before recharging the system.
