Properties

A rubber plug is a machine building element used for sealing openings:

• ends of pipes and holes in plates or sheets
• also oval and other non-circular forms
• plugs for holes in sheets usually have a groove that matches the thickness of the sheet and secures the plug in the hole

Stoppers and base plugs are used to receive impacts; they are of bulky rubber. Common application is stoppers for outer doors.
