Wireline Spring Jar

Wireline Spring Jars are used to provide upward jarring impact during wireline fishing operations. Spring Jars can be used in place of Hydraulic Jar. These Jars are run between Stem and Mechanical Jar in tool string.
A Hydraulic Load Calibration Tool is available as an optional extra to allow the Spring Jar to be surface load set and tested prior to running in the well.

Other sizes are available on request.
