TC-1W Wraparound Pack-offs
The TC-1W is a split, wraparound pack-off that allows tubing-string manipulation to displace fluid while maintaining complete control of annular pressure. Like all TC Series pack-offs, tubing string weight must be suspended from a tubing suspension adapter or coupling adapter. The TC-1W has a compression-type seal which is actuated by lockdown screws.
- Considered a primary annulus seal
- The compression seal is actuated utilizing lockdown screws
- Lockdown screws also retain the pack-off in position
- Seats in the TCM, TC and TC-60 tubing head bowl
