Elite Ceramic Buttons

Elite™ Ceramic Buttons are made from proprietary yttria stabilized zirconia, which is the toughest ceramic commercially available on the market. This offers high strength and toughness as well as exceptional corrosion resistance. With a maximum application temperature of 900F, they also provide superb resistance to high heat. Used extensively in downhole tools, they have become widely chosen for mud pump liners, bottom sleeves in drilling, bridge and frac plugs and many other new multi-stage frac systems.
