Product summary

Mechanical Link Jars, also referred to as “Spang jars” are designed to act like a sliding hammer.

Utilising the weight of the Stem Bars, located immediately above to convey powerful jarring impacts, bi-directional impact forces (jarring actions) are achieved by controlling the direction and speed of the Slickline at surface

The effect of a given jarring action will depend on the speed of movement, stem weight, the jar’s stroke length, tubing size and deviation, fluid viscosity and well pressure.
