Product details
Best-all pistons with replaceable rubbers is one of the oldest and most widely used piston styles worldwide. It offers an economical option for drilling low-to-medium-pressure wells with water-based fluids, fully compatible with API standards.
Our proven rubber piston is the heart of this design. Only the finest raw materials are used to ensure optimal performance, and our rigid quality-control standards ensure consistent, repeatable performance-piston after piston. The design of the seal has been refined over many years to deliver optimal field performance. The fabric-backed heel provides additional stiffness and acts as a reservoir to hold and distribute liner wash fluid to the piston-seal area.
The piston hub is manufactured from high-grade steel, and extra care is taken to ensure concentricity. Replacement rubber assemblies come complete with rubber, snap ring, and washer plate.
Designed to meet pressures of 5,000 psi and temperatures up to 220°F for superior performance.
100% interchangeable with Mission Premium, Southwest RNR pistons.
Available from 4" to 7".
