Graco is excited to announce the launch of new HFR packages for sealants and adhesives available for sale as of March 2012.

The HFR proportioner packages, designated HFRS, for sealant and adhesive materials include; a HFR proportioner, inlet fluid regulator, MD2 valve and material hoses. Complete systems including; HFR proportioner package, Check-Mate™ pumps and supply hoses are also available. Both the proportioner package and the complete systems are available in either carbon steel or stainless steel. The HFR packages are available from a matrix of part numbers starting with HFRS01. These part numbers are shipped complete, but require installation.

These new packages are designed to handle the following sealant and adhesive materials including; silicones, epoxies, modified silane and urethane with viscosities exceeding 2 million centipoise. Most common ratios are available; 1:1, 2:1, 4:1, 5.33:1, 6:1 and 10:1, additional ratios are available through our systems engineering group.

In addition to the proven performance of the HFR proportioner and Check-Mate supply pumps, these new packages provide the following benefits:


  • Uniform bead assures proper adhesion or seal
  • Meets demands for low-flow precision beads
  • Ratio assurance reduces waste and improves quality
  • Data reporting
