Replaceable Rubber Pistons

Our replaceable rubber piston is made with HNBR to resist extrusion and abrasion. The two piece design allows for rubber replacement at lower operating pressures, while the robust construction makes it suitable for running at pressures up to 7500 PSI. In a very wide range of drilling conditions, the replaceable rubber piston can run in fluids from clear water up to heavy weight drilling mud. These pistons are fully interchangeable with most other manufactures products. Available sizes range from 3" through 7-1/2”.

Premium bonded PU piston

Premium bonded PU piston apply advanced polymer compound, which provides strength to withstand chemical attack from additives used in today's oil, synthetic and water based drilling fluids. The compound also has improves abrasion resistance from drilling solids , capable of operating in fluid temperature up to 300°F.

Applications

High Pressure Drilling.

Elevated Mud Temperature.

Synthetic Drilling Fluid.

Ceramic and Zirconia Liners.

Chrome Sleeved Liners.

BONDED RUBBER PISTON

Bonded rubber pistons are constructed of HNBR, bonded to a solid metal hub. The oil resistant rubber is designed to provide optimum performance in oil base or water base mud and high drilling pressures.

The oil resistant rubber is designed to provide optimum performance in oil base or water base mud and high drilling pressures.
