Cayman™ LB Wellhead Penetrator System

Cayman LB Wellhead Penetrator

PFT's Cayman™ LB Wellhead Penetrator System is our innovative alternative to low-tier systems that use epoxy putty, resulting in a non-positive gas barrier. In the Cayman™ system, existing cable terminates below the wellhead, inside the lower connector. Solid PEEK™ insulators create a positive barrier, blocking any migration of gas or fluids to the surface. Our Cayman™ Lower Connector is field-attachable and in most cases can be assembled on a cable in less than 20 minutes. The Cayman™ LB surface junction is fully sealed and certified for hazardous locations worldwide.
