Not Your Average Piston: Behind the Scenes of Our Custom Builds

Written by mearthane | Apr 15, 2025 8:19:29 PM

Ever wonder what goes into making a high-performance piston that can take a beating and keep on pumping?  We’ll give you a hint—it’s not mass production, it’s not cutting corners, and it’s definitely not one-size-fits-all.

At MPC, custom pistons aren’t just “parts”—they’re precision-engineered, performance-tested workhorses. We’re pulling back the curtain to show you how we build pistons that hold up under pressure—literally.


Behind the Scenes: From Concept to Completion

Whether it’s destined for a mud pump facing extreme heat and pressure—or another punishing environment—each piston goes through a carefully controlled build process:

  • Custom Mold Creation - We start with your design—or even a napkin sketch. Need help refining it? We’ve got you.
  • Urethane Bonding - Using oil-resistant polyurethane, our pistons expand with fluid pressure to maintain a tight seal—even in worn liners.
  • Inspection & Quality Control – Every part is inspected for flawless bonding, tight tolerances, and rugged reliability. “Good enough” isn’t in our vocabulary.

Built for Performance

Our custom-molded pistons are designed to:

  • Withstand pressures up to 7,500 PSI
  • Perform in standard and high-temperature environments
  • Work with oil-based, synthetic, and water-based mud systems
  • Deliver long-term durability—lasting longer than rubber and reducing replacement costs
These pistons are made to last—no shortcuts, no compromises.

Proven in the Field

We’ve made thousands of custom pistons for some of the biggest names in oil and gas. While we can’t name names, we can say this: when customers need something that works, they come to us.  Whether you’re looking to extend run life, reduce downtime, or just want a part you can count on, we’re ready to help.
