Next Generation Skwezloc Concentric Locking Collar Design

 

The Skwezloc® concentric locking collar design first debuted in 1966.  In the early 2000’s, more competitive designs with concentric locking collars were introduced.

 

These designs require Turned, Ground, and Polished (T&P) shaft tolerances.

 

The Sealmaster next generation Skwezloc Concentric Locking Collar has been redesigned to accommodate “Commercial” Turned and Polished (T&P) shaft tolerances with improved lock reliability of T&P shaft tolerances.
