The PurpleSeal™ PS-C is an all-composite frac plug with ceramic buttons in the upper and lower slips, rated at 10,000 psi (68.9 MPa). Proprietary high-strength composite materials ensure uniform performance and durability. 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. Zero metallic content and less material volume will result in outstanding drill-out performance.  PurpleSeal PS-C frac plugs consistently drill out in 6 minutes or less
