Plastic Reusable plugs are also known as Re-Plugs. They are removable for inspection and maintenance and can be reinserted multiple times. They come in black, beige or bright yellow for easy identification in places like bridges, marinas or docks. While they are threaded, they can be tapped in with a hammer, but you need a special tool to remove them. The tool is about $7.00. Plastic plugs should be used whenever Bor8 Rods or Impel Rods or any internal treatment is used.

These come in black, beige or bright yellow for easy identification in places like bridges, marinas or docks. The 5/8" size is to seal holes for the 1/2" Bor8 Rods. This price is for a single plug.
