Petersen can manufacture Annular Seals and inflatable seals for almost any size, pressure, chemical, and temperature requirements.

Annular seals can be made with a continuous seal to slip over the end of a pipe or open-ended to form around a pipe already in place.

The Petersen® Multi-Flex® Annular Seals are very flexible, easy to install, and have many inflation connection options.

These seals are ideal for bypassing a pipeline during repairs or any other temporary small to large pipeline connection.

For a quote please provide:

  • Inner seal diameter
  • Outer seal diameter
  • Head pressure to hold back
  • Any unusual chemical or temperature requirements

Warning: All pipe plugs must be blocked or anchored adequately against a force equal to the head pressure times the cross-sectional area of the pipe.

Debris or protrusions in the pipeline can damage a seal or rupture inflatable plugs.

NEVER use an inflatable plug when its failure could cause injury or catastrophic damage or as the only means of protection for personnel working downstream.

NEVER use a test pressure greater than the capacity of the weakest pipe or component in the system.

Actual conditions vary so user must accept full risk and responsibility for the selection and use of any product.

Please review the Warranty, Terms and Conditions.

Note 1: Mechanical and Molded Rubber Plugs are generally used for testing because fabricated Multi-Flex® style plugs may allow some seepage unless customized for a positive seal.

Note 2: We are constantly upgrading our products and while we try to keep the websites up to date it is possible more current specifications may be on a quote or confirming order. Images are typically representative and may not be an exact representation especially of the item size.
