Piston Assemblies

Our Sapphire, Ruby, or Ceramic Piston Assemblies are manufactured using a proprietary "press fit" or "heat set" process that ensures the tightest piston OD and ferrule ID tolerances in the industry. Most competing products use adhesives to assemble the piston rod into the ferrule, which can impede pump performance. We provide ODs down to ± 0.00001" with surface finishes down to 0.25 microinch (Ra). We offer exclusive grinding and lapping processes for cost effective, quality components in high volumes Custom piston diameters from 0.015" to +2.0".
