00SO Slip on Stop Collar

00SO Slip on Stop Collar

High strength 00SO slip on stop collars are developed for use in challenging wells. They provide a high-performance method of securing and protecting centralizers on the casing string.  

Made from the same material as our ultra-high strength centralizers, the 00SO robust design can withstand high axial forces, making them suitable for demanding well conditions. They are heat treated to increase strength and reduce brittleness. 

Unique set screw design provides industry leading holding forces without excessive marring of wellbore tubulars. 

Available with single and double-row HD set screw configurations depending on casing size. 


00SO stop collars are designed for applications with Centek’s premium range of centralizers for challenging wellbore sections.

Performance ratings

Stop collar performance depends on the ability of the stop collar to hold the centralizer in place. This aids 'runability' and is measured by holding force and integral strength. To help with product selection we've added a rating to all our stop collar products for runability and strength.


00SO stop collars are available in sizes from 2 7⁄8" to 20"
