When I replaced a check valve the old one had a rubber gasket that I used on the new one since the new one didn’t come with one!
Good Luck
Same thing with mine. Look at your old check valve. Mine had a rubber piece that inserted into one end. Put that in the new one and everything worked fine. If you already tossed the old one you should be able to find a close replacement washer at a hardware store.
