Tube Jar

Tube Jar


The tube jar is used for special tasks when spang jars are not practical.


Tubular jars have five components:

1. Fishneck

2. Barrel

3. End Cap

4. Nut

5. Stroke Rod


Tubular jars operate and serve the same tasks as the spang jar. Tubular jars are often used in casing for wireline fishing jobs and sand bailing.


As with other jars do not remove toolstring from bottom of hoisted lubricator with jars still connected.
