Intensifier Jar

Two-in-one acceleration tool and wireline shock absorber

The Impact Selector Intensifier Jar delivers powerful functionality; it can be used as an acceleration tool or a shock absorption device, depending on where it’s positioned in the toolstring. It can also be used as a wireline stretch simulator device when used with an Impact Selector Jar.

When positioned below the rope socket, the Intensifier Jar provides highly effective shock absorption to help prevent tool or wire damage, ultimately improving efficiency.
