The safety joint provides quick release of the test string if the string below the packer becomes stuck. The tool string and downhole gauges above the safety joint can then be recovered; the lower stuck portion can be retrieved by either fishing over the OD of the box section or by reengaging the pin section into the box section.

This Model is drifted with the corresponding API tubing drift size.

NOTE: Additional size, weight, end connection etc. are also available on request.
