The SPIR-O-LIZER is a die cast, zinc alloy, solid blade centralizer designed to reduce torque & drag while running casing. The blade design will create turbulence, promoting 360° cement coverage.


  • Manufactured from zinc alloy providing:
    • High strength - allowing thinner wall sections giving maximum flow-by
    • Exceptional wear resistance - maximum standoff
    • Low coefficient friction - reducing torque & drag
    • Withstands temperatures up to 400° F
  • 360° spiral blade configuration gives maximum standoff assisting with hole cleaning and cement placement
  • Self-cleaning blade design to reduce the risk of packing off
  • Over one million units run


  • Centralizer placement/T&D analysis available
  • Fully machinable allowing for custom ODs
  • Split units available
  • Size range from 2-7/8" through 13-3/8"
