O-ring for Febco 765-1

The vacuum breaker of my Febco 765-1 system leaks. It seems the black O-ring (the larger of the two, diameter 2 1/4 inches) needs to be replaced. I check the Febco online a number of times but cannot locate the part. Is there a way I can order a replacement? HomeDepot does not carry them.

You can go through a company out of california called "Bavco" the stock parts for every backflow assembly ever made. They will also ship your parts overnight. The sales staff is very helpful they know all parts for all vackflow assemblies. Their phone # is 1-800-458-3492. The website

Hope this helps.
