The PurpleSeal™ Bridge Plug is a hybrid-slip “kill” plug that provides temporary wellhead isolation from the zones below after a frac. The plug contains a cast-iron upper slip and powdered-metal buttons in the lower slip. The plug is rated to 10,000 psi from above and 8,000 psi below. Proprietary high-strength composite materials ensure uniform performance and durability at temperatures up to 200° F. Interlocking castellations on the slips and end caps and a contoured interface between the slips and cones eliminate component rotation to ensure even, concentric slip expansion. The plug ID is sealed by a trapped composite component that is drilled out prior to the upper slips to equalize pressure.
