kelly saver subs are stocked or manufactured to our customers request, based on API requirements.

A kelly saver sub is used to prolong the life of the kelly by taking the connection wear each time it is made up to a drill stem component. The saver sub connection is sacrificed because it can be easily repaired or replaced.

The saver sub can be equipped with a rubber protector to reduce BOP equipment and casing wear resulting from contact damage with the lower kelly configuration.
