Yes, the Single Port Water Valve 640908/637580/618253/633325 is listed as the replacement for the 618253. It has been discontinued by Norcold, so it's only available while our remaining stock lasts. Newer versions may use a quick-connect fitting instead of a threaded one.
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.
