Bundle of two EPDM 104x114x6mm D-Rings and two 1x35mm silicon seals for the handles. Seals should last for many many years so there's no reason to change them unless you damage or lose one.
Note: The Silicon washers are custom made. But if you only need D-Rings, they are 104x114x6mm D-Rings and you might find them at a store near you. Other food-grade Silicone, EPDM, NBR, FKM black, transparent or blue of the same size will work as well.
