 Top Plugs:
The Bottom Cementing Plug is designed to exert continuous pressure on the casing wall. The core is made of special materials such as Plastic, Aluminium or Phenolic depending on the application and well conditions. The tapered base fits the cavity of the bottom plug initiating a positive seal. A solid rubber top plug is also available.

Bottom Plugs:
Like the Top Cementing Plug, the fins and tail section provide positive wiping action. Fins also serve as a seal while cementing. The core of the bottom plug also made of special materials such as Plastic, Aluminium or Phenolic depending on the application and well conditions. A rubber diaphragm at the top of the plug ruptures after the plug is seated allowing cement to flow through.


The phenolic core of the wiper plugs has a breakage design for early breakage of the core with the bit without reducing the effectiveness of the core. The second unique design is the controlled expansion engaging the wall of the casing like a packer, compressing and locking the outer body and fins of the wiper plug firmly against the inner wall of the casing with only 1000 psi differential pump pressure on the plugs.
