BONDED RUBBER PISTONS
REPLACEABLE RUBBER KIT
F&CO OILFIELD SOLUTIONS distributes the benefits of our bonded-piston design with a nitrile-based elastomer compound for water-based drilling fluids. While urethane pistons can be used in water-based muds, they perform best in oil-based and synthetic fluids. The best option for water-based drilling fluids is the nitrile-rubber compound.
Bonding the rubber to the metal hub provides the strongest, most extrusion-resistant style of piston available also minimizes any leak paths from forming on the inner diameter of the piston. The bonded-lip design has an open inner sealing lip that also enables the rubber to expand inward as a result of thermal expansion without excess loading of the sealing lip.
With proper cooling and lubrication from the liner-wash system, the bonded-nitrile piston can be used successfully at temperatures up to 250°F (121°C).
