Plumbing – Flat PVC Cap to fit a 3″ PVC pipe

plumbingpvc

I'm looking for a flat PVC cap for 3" PVC pipe. I ordered a few 3" PVC DWV Schedule 30 Caps Amazon that were too small.

I've measured the 3" PVC pipe, and it appears the outer diameter is just over 3.5", so the cap's interior will need to be that size.

I've found some in the local hardware stores (Lowes, Home Depot…etc) that fit, but are rounded on the top. I need them to be flat. I know they exist, but can't figure out what they're called, or how to find them for sale anywhere (online or other).

Question:

What is the name of this PVC product and how/where can I find them for sale?
