Tubular Jars Guiberson tubular jars make swabbing safer by allowing a
full 20 in. or 30 in. stroke to jar loose accidentally stuck swabs.
These steel jars provide heavy hammer surface that will not kink or lock
up due to twist. Their piston construction allows both swivel and
knuckle action, ensuring trouble free operation and longer swab cup
life. Large ports allow free circulation and eliminate sanding up.
