Pressure Control W2 Casing Head with S4 Surelok
 Connector
The S4 Surelok™ weldless casing connection offers a simple 
and quick alternative to welded bottom casing heads. With 
the ability to be installed without welding, this connector is 
ideal for applications where an open flame is a safety or time 
lost concern. Most sizes can be safely installed in less than 60 
minutes.
Rated for the loads imposed by the casing head and BOP 
operations, this readily reversible connection is ideal for 
the most demanding temporary or permanent wellhead 
installations. Field-proven, API qualified elastomer seals on the 
casing stub are externally testable. The slip system is easily 
activated to provide full locking engagement with the casing 
stub even under tension, compression and/or bending loads.
With the use of the optional adjustable baseplate, subsequent 
casing and drilling loads can be transferred to the larger  
conductor pipe.
