Lubricated Bumper Sub

Bumper Sub

Lubricated bumper subs provide axial movement and bumping action in a fishing string to help free stuck equipment and engage or release fishing tools. They can deliver upward or downward bumps and help maintain controlled weight on milling and cutting tools.

A sealed, lubricated spline drive transmits torque while the tool strokes, reducing friction and wear. Tungsten-carbide-coated external sealing surfaces provide added resistance to wear and corrosion.
