    These plugs work
  

*by M***B on Reviewed in the United States on July 27, 2022*

Got these to plug some tomato watering stakes so that water is released over time.  Outside in the heat, they are working just fine.  Edges are not rough and material has some give.

Was having trouble with my exhaust sitting on my frame for some reason.  Put one of these in between while I figured out the problem.  Didn't melt, didn't even deform or discolor.  Impressive!
