Make Life Good in the Pump Room
Engineered to outperform all other polyurethane pistons on the market today, Patriot™ ST Pistons are built to be compatible with and deliver superior performance in today’s OBM and synthetic drilling mud. Longer piston life equates to longer liner life, greatly reducing the costs associated with mud pump expendables and the time involved in making the necessary changes.

Designed to meet pressures of 7500 psi and temperatures up to 220°F, the Patriot ST Piston difference is in the solid lip bullnose designed head which is composed of two different durometer urethane compounds bonded together for superior performance.
