Plunger illustration for die casting lubricants pageSemi-synthetic Oil-based Lubricant for Diecasting Foundry

Plunger Lube™ 3000 is a semi-synthetic, oil-based lubricant for plunger tips and sleeves for casting aluminum and magnesium alloys. Plunger Lube™ 3000 contains unique additives to promote adhesion of the lubricant to the plunger tip for unsurpassed lubrication without graphite. 

Plunger Lube™ 3000 provides exceptional performance while minimizing smoke emissions and the evolution of gasses. Plunger Lube™ 3000 has a honey-like appearance with a desirable consistency for manual or automatic application.


  • Tenacious film minimizes usage.
  • Excellent wetting and lubrication properties.
  • Outstanding tip adhesion avoids waste and mess.  
  • Improves tip and sleeve life.
  • Minimizes flame and smoke emissions.
  • Reduces plunger lubricant related porosity.



Apply neat with bush or through automated spray or drip systems.
