LEAD FILLED STEMS

ACT  Lead Filled Stems are used to provide additional weight to the tool string, without a change in & length. These are normally used in well bores with high pressures, to counter the force created by well pressure on the cross section of the wireline. However, these should not be used for heavy jarring.
