P seal is constructed from an elastomer with back up rings for anti-extrusion. Energized by the injection of sealant, it is a static seal that is used to seal rough casing and tubing. Backup rings are available in Mesh Stainless Steel or Solid Carbon Steel.

The standard P Seal is a one-piece molded seal utilizing molded-in anti-extrusion device. This design enhances assembly by eliminating the loose anti-extrusion devices used in other designs.

P seal is installed in the lower sealing area of casing spool or tubing head. It is used to provide redundant well safety between casing annulus and flange connection of casing head, casing spool or tubing head. In some cases, it can also provide special sealing capacity for fracturing equipment.
