Hydraulic Fishing Jar

The hydraulic fishing jar combines optimal impact characteristics
with high-endurance construction to provide reliable fishing performance in harsh downhole environments. Tool seals are temperature rated to 500 degF and pressure rated to 20,000 psi, and the temperature compensation system in the detent permits prolonged jarring without loss of impact force. The closed drive system prevents wellbore fluid from entering into the drive section, improving tool performance and reliability.
