Patriot Pistons

Patriot Oilfield Expendables has introduced three high quality bonded urethane pistons designed to operate in the harshest drilling conditions around the world. All three mud pump pistons are unique in their own way and are designed to outperform in performance against all other piston in the market. The Patriot Piston line is trusted both domestically and internationally by the largest contractors in the world. Patriot Pistons maintain continued success from the smallest land rigs to the world’s largest newly built high specification drill ships entering the market facing today’s toughest drilling environments.

Standard Features for Patriot Piston Line:

  • Dual-Durometer bonded urethane
  • Resistant to high pressure, abrasion, heat and extrusion
  • ½” Piston surface area reduces friction and liner wear
  • Solid bullnose lip design seals for less squirt
  • Cut back hub design reduces liner wear

Patriot HPHT

Patriot’s HPHT piston is the standard and most commonly offered piston. Patriot HPHT Piston is built to be compatible with and deliver superior performance in today’s oil based and synthetic based drilling muds. Longer piston life equates to longer liner life greatly reducing the operating cost associated with mud pump expendables and the time involved in making necessary changes. The Patriot HPHT has competed against all other like manufacturers and has outperformed every time.
