I can't confirm the right fitting to connect your old compression line to the threaded port on the new 640908 valve from here. A hardware store adapter usually does it.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
