Hydraulic Jar
The DTI Hydraulic Jar impacts upwards using is a timed delay oil feeder system. This system enables pull resistance so that the time taken to fire is directly proportional to the amount of pull tension on the wireline. Often used in conjunction with Link Jars, the effectiveness of the jarring impact is largely dependent upon the tension placed on the wireline and the weight of stem bar attached immediately above the Link Jar.
- Field proven firing mechanism
- Firing load determined by Wireline pull load and can be varied by the Wireline Operator
- Precision manufactured body and piston generates consistent firing time
- Each tool is fully tested prior to leaving DTI manufacturing
- Balance piston increases operating window
- Advanced material selection increases service life of the Jar
DTI offer alternate sizes, materials and thread connections. Please contact us for more information.
