The O-ring is the part that seals the filter cap to the engine itself. It is re-usable many times if there is no damage or it isn't starting to get flattened or squashed. The Hi-Flo HF-136 oil filters I bought for the GZ did not have an O-ring and I never had a problem using the original. Most larger auto parts stores have a selection of O-rings so you don't have to find a dealer and pay their prices.
The Hi-Flo oil filter fits many different engines and it wouldn't be cost effective to include the rings to fit every application.
