Maybe I'm wrong but I don't think the hole should be 1 3/4 inch and should be able to accommodate that size pipe, when advertised as hole 1 1/2 inch. The 3 inch side seems closer to 3 inches. If you look at my photo you will see that I had to overtighten the yoke for quite a large portion of its length. I mean the rubber plays pretty well since it had to squeeze quite a bit to get the 1 1/2" tube to seal. It works but I was hoping to play around a bit, not literally add an extra 1/4 inch Space.As I said maybe that's what they meant and I'm not familiar with this type of connection.Overall it works as intended and is made from excellent materials.
