No no from core and schedule 40 are not different sizes you are totally wrong.
If foam core and schedule 40 were different size od you would have to buy different fittings. IVE BEEN A PLUMBER FOR 36 YEARS. EVEN THIN WALL PIPE HAS THE SAME OD. The od of foam core and schedule 40 pressure are EXACTLY THE SAME. Folks these things work perfectly but yes it’s a bitch to get them inserted but that’s why they don’t leak. Put grease or soap on them and use a lever to force it into place. YOU MUST CHAMFER THE PIPE on the end to get it through!!! To the guy that said schedule 40 and foam are different sizes…….NOPE

Purchased 3" pipe grommet. Instructions said to cut a 4" hole (using hole saw), but did not seem very tight in hole.

With a slight redesign this would be a 5-star product instead it's a 1-star
If these were engineered slightly better it would be a great product. I don't understand how the manufacturer can be so incompetent and so clueless about their own product. This 3 inch uniseal is designed to work with a 3-inch PVC pipe. But not schedule 40 PVC which is the standard it's designed to work with the foam core. The foam core is way smaller diameter than the standard schedule 40 PVC. Unfortunately the 4 inch hole that they instruct for you to drill for these is slightly too big to accommodate the foam core PVC. The schedule 40 PVC is so much bigger that it will form a tight fit as long as you are trying to shove the pipe into something that can deform its shape. Mainly thin plastic. The fitting will be so tight you will not be able to get it back apart without destroying whatever you had it inserted into. If the manufacturer had designed these with a slightly larger diameter it would be a near-perfect products. But most of their uniseals have bad information supplied with them and they are not capable of being used as advertised. For instance a one and 1/2 inch uniseal will not fit a 1 and 1/2 inch pipe like they say it is actually for 1 and 1/4 inch pipe.
