The PurpleSeal™ PS-X is an all-composite frac plug with powdered-metal buttons in the upper and lower slips, rated up to 10,000 psi (68.9 MPa). Proprietary high-strength composite materials ensure uniform performance and durability at temperatures up to 250° F (121° C). 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. With minimal metallic content—approximately 1%—PurpleSeal frac plugs consistently drill out in 8 minutes or less.
