High-strength 00SO slip-on stop collars are engineered to deliver exceptional performance in the most demanding well conditions. Designed for use with Centek’s premium range of centralizers, the 00SO provides a reliable and high-performance method for securing and protecting centralizers on the casing string. Made from the same ultra-high-strength material as Centek’s top-tier centralizers, these stop collars are heat-treated to enhance strength and durability while minimizing brittleness. Their robust design withstands high axial forces, ensuring reliable performance in challenging wellbore environments.

The 00SO stop collars feature a unique set screw design that delivers industry-leading holding forces while reducing damage to wellbore tubulars. Available in single and double-row HD set screw configurations, they are optimized for various casing sizes and perform exceptionally well on casing grades up to P110. With anti-vibration screw retention and the ability to exceed API 10D-2 performance standards without requiring 4 inches of axial slippage, the 00SO stop collars are a premium choice for operators seeking maximum reliability and efficiency in demanding onshore and offshore applications.
