HFR Metering System for Sealants and Adhesives 

Hydraulic fixed ratio system for two-part epoxies, silicones, adhesives

Designed for flexibility, the Graco HFR Metering System handles two-component materials including epoxies, silicones, resins and more. With its accuracy and repeatability, the Graco HFR lets you hit a specific ratio and volume – the first time, and every time. You reduce scrap and rework with accurate, on-ratio dispensing.

Configure the components essential for your application

  • Select what you need for your material and application – no more, no less
  • Faster lead times – configured equipment solutions are delivered to your door faster than a custom engineered solution
  • Easier maintenance with standard parts
  • Service is there when you need it through Graco's global distribution network


  • Precision, on-ratio dispense reduces material waste for a better bottom line
  • More technology for less money
  • Fully configurable
  • Stores 100 shot sizes and five sequences of 20 positions each
  • Compact footprint saves space in your plant
  • Intuitive, easy-to-use controls simplify training
  • Integrated USB lets you download process data onto a flash drive for further analysis
