I needed these caps to be more flexible because the holes to be filled were same size as caps. I will just have to find another use for them.

I’m using these to plug the stock gauge mounts on a 2015 FXDL. These fit snugly and blend in perfect. Saved me quite a bit of $ also! No issues at all.

These fit on my 2005 Ford Truck F150 1/2 ton P/U 2WD 5.4L EFI SOHC 8cyl with 4" Putco Boss Bars side rails. Much less expensive than OEM. We'll see how they hold up!

Advertised that is would fit onto a 4" PVC pipe but is did not, it slid into the pipe. Miss leading. Very disappointed.

read their description of the range of dimensions of the cap. i wanted to seal a 4" cast iron toilet pipe for permanent covering. this cap and 1/4 tube of loctite clear silicone sealant did the trick.
