Expansion Plugs
expansion plugs are mechanical sealing devices that are inserted into a hole and then expanded so they press tightly against the surrounding material, creating a secure, often leak‑tight and long‑term seal. They are commonly used to close or seal machined or cast holes in components, piping, or pressure‑containing parts by using a mechanical action (such as driving or tightening an internal element) that causes the plug body to expand radially and lock in place.
