      OMG! Black rubber plugs!!!!!!. I got out the old laser micrometer and measured them. They were within .000165 of 1 inch accuracy. I have bought thousands of other plugs in my life and none compared to these. You just have to get some... actually get many of many assorted size. you won’t believe this I stuck it in the hole of a big lawn roller filled with water, hit it one time with rubber mallet, and it has not leaked for two weeks now! This rubber plug is an absolute game changer. Don’t know how I ever got along without it.
