I'm not sure which model you mean by "55." The Single Port Water Valve 640908/637580/618253/633325 is the standard Norcold ice maker valve. It has been discontinued by Norcold, so it's only available while our remaining stock lasts.
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.
