Upstroke Jar
Alloy Steel&Nickel Alloy

The Upstroke jars are used for jarring upwards during wireline pulling operations. The advantage of using an upstroke jar as compared to a hydraulic jar, is that it is fully mechanical and has no seals, permitting its use in gas wells.
Size | Fishing neck | Connection |
1.5＂ | 1.375＂ | 15/16UN |
1.5＂ | 1.375＂ | 1.5QLS |
1.875＂ | 1.75＂ | 1-1/16UN |
1.875＂ | 1.75＂ | 1.875QLS |
Note: More customized parts are available upon request.
The upstroke jar incorporates a ball locking mechanism and a compression spring tensioning system. The central shaft is abruptly unlocked when the compression force of the spring is reached, so delivering an upward jarring impact to the tool string.
Different tension rated springs are fi tted to give optimum performance depending on the depth in the well.
