Choosing a dildo for harness briefs

I’m thinking of getting this for the wife as a surprise (not complete surprise, we have talked about pegging in the past)

I’m a bit confused about which toys are compatible. It says it’s suitable for dildos with a 4.75" dia, but it doesn’t say the o ring size. Meanwhile, many of the toys say a desirable O ring size. How do I know what to choose?

We have the briefs. Don’t choose a dildo with a massive suction cup as you can hear the ring cracking as you try to insert the cup through the hole.

If it fits a 4.75 inch circumference dildo then it should be a 1.5 inch o ring.

You can filter dildos by circumference size (although it will show you 4-5 inches) but the product page should also list the circumference size in the specification section.
