Stem

Purpose

The stem is a device that essentially helps to add weight to the tool string. It provides the hammering action to the tool string which in return allows the jars to transmit force produced by the movement of stem bars. Extra large and extra small OD stems are used based on different well conditions.

  • Inquire about quick connect stems and higher weight tungsten filled stems. *
