First off, only one comes with this page, even though it says, "2-pack" with the little Amazon smile under it, so don't get your hopes up. I though I was getting a good deal and ended up paying twice as much as it's worth.

The inside diameter of the larger bell end is 3.977 inches. It tapers to 3.665 inches, which is the ID of the small end, which is straight walled as opposed to the tapered bell end.

The OD of the straight section is 3.91 inches.

Overall length is 3.98 inches.

It'll work. I'm a little miffed that it said 2 and only 1 arrived.
