Centek UHD Stop Collar — Ultra Heavy Duty Holding Power for the Toughest Wells
The Centek UHD Stop Collar is engineered for the most demanding well environments, delivering exceptionally high holding forces where reliability is non-negotiable. Designed specifically for challenging applications — including flush casing joints, where traditional stop collars struggle — the UHD provides a robust, dependable solution without requiring specialist installation procedures.
Built on Centek’s proven approach to heavy-duty casing equipment, the UHD Stop Collar uses a precision-machined design with multiple sets of high-strength set screws, delivering ultra-high holding force while maintaining a secure, slip-resistant connection under extreme axial and lateral loads. This makes it a formidable competitor to other high-holding-force devices on the market.
The UHD Stop Collar is ideal for operators who need absolute confidence that their centralizers will remain securely positioned throughout running, rotation, and cementing operations without the need for specialist installation equipment.
UHD stop collars are developed as counterparts to the S2-HD heavy duty centralizer.
UHD stop collars are available in sizes from 7" to 11 7/8"
