• Minimum number of parts

• Packoff is automatically energized with casing  weight

Available in standard API casing sizes.

Secondary Seals

TVC’s PE secondary seal is inserted in the bottom preparation of a casing spool or tubing spool and retained with a snap wire. The seal is energized when the spool is installed over the casing stub and the flange connection is made up.

TVC’s HPE secondary seal is designed for high­pressure applications. The bottom compression plate is threaded and is inserted in the bottom preparation of casing spools or tubing spools with threaded preparations.

Available in standard API casing sizes.
