B-1 Tubing Head Adapters

Sentry’s B-1 adapters can hang tubing utilizing tubing threads machined into the bottom ID of the flange. These are employed when an operator wants to reciprocate tubing as part of the completion process. Additionally they can be used as a non-suspension adapter when employed with the TC-1A or TC-1A-BP tubing hangers. They are used with threaded valves in low pressure applications.
