Pin and Collar Tube Plug

For permanent plugging of condenser and heat exchanger tubes and tube sheet holes, the two-piece tapered design of the Type 2 Pin Plug is machined to match specific tube sizes ranging from 5/8” to 1-1/4”. The pin and collar plug provides an exceptional full-length seal at high temperatures and isolates leaking tubes from the system, allowing continued use of the unit without major overhaul. The two-piece design is a snap to install using a mallet, and can even be welded into place. For applications where a collar isn’t necessary, consider the Conco Type 1 Pin plug.

  • Available in brass, bronze, stainless steel and titanium
  • Special materials and sizes can be custom manufactured
  • Can be machined to your drawing specifications.
How It Works

The two-piece design of the pin and collar plug provides a tapered pin plug matched with the positive full-length seal of a collar to provide a permanent plugging solution for tubes or tubesheet holes.
