Cementing Plugs

We manufacture a complete line of downhole oilfield wiper plugs. Sizes range from 2-3/8” tubing plugs to 16” casing plugs. We offer standard rubber covered plugs with aluminum cores and premium, PDC drillable, plugs molded from urethane.

Our standard elastomer for our rubber plugs is SBR. We also offer Nitrile, HNBR and Fluorocarbon (FKM) for higher temperature applications and XNBR (Carboxylic-acrylonitrile-butadiene) for higher wear resistance. These materials are available in both our top and bottom plugs.
