Critical to your Reactor system

Graco’s heated hoses are designed specifically for use with Reactor Equipment. Hoses are a key component to the total system, making it important to achieve accurate and uniform heating for the best application possible.

New multi-strand copper heating element has greatly increased hose quality

  • Provides 10-times* the flex life compared to previous flat copper heating element
  • Long-term, even heating without hot spots
  • Backwards compatible with existing Reactor heated hoses

*Testing based on 1/4 in. 2000 psi heated hose


  • Copper-heated hoses are designed specifically for use with Graco proportioners
  • Covered with proprietary butyl cover for protection against moisture sensitive isocyanate
  • Hoses are covered with foam insulation for heat retention
  • Different fitting sizes on the isocyanate and resin hoses prevent accidentally connecting the wrong hoses together
  • Hoses use custom designed splice kit to electrically connect hoses without having to run copper under the fittings
  • Helix-design whip hose uses braided copper wires for added flexibility and longer life
  • Whip hoses 246050 and 246055 come standard with the new Xtreme-Wrap Scuff Guard
  • Other selected hoses may be ordered with the Xtreme-Wrap Scuff Guard for added protection and prolonged life


Joint Protectors

Joint Protectors provide additional protection at the most vulnerable section of the hose: the electrical connections, hose fittings, and fluid temperature sensors. All 50 ft hoses with the new Xtreme-Wrap will come with one Joint Protector.
