Can I use them on a round surface like the side of a 5 gallon bucket?

Yes, I believe they were made for that very thing! I used mine on the cover of a 5 gallon bucket. It's a tight fit, but works very well.

Will a 1 inch OD work?

No, your pipe OD must be 1.315'' (33mm) just like 1 inch pvc pipe.

How many pcs for 1 order?

You will receive two Uniseals. (2 pack)

Are these seals NSF certified?

There is nothing that would indicate a NSF rating on the packaging or product. My answer is NO.
