Good To Know

Q: Does this adapter contain a core depressor? A: Yes, it features an integrated core depressor to safely actuate the Schrader valve on the service port.

Q: Is this adapter compatible with older R22 systems? A: R22 systems typically use 1/4-inch service ports, so this 5/16-inch adapter is specifically meant for modern high-pressure R410a systems.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
