Unfortunately, it's not made anymore. The 618253/ 640908 single port valve and its later replacements have all been discontinued, and Norcold hasn't released a newer part. We'll let you know if we come across 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.
