The Graco 249587 Reactor Heated Hose (25 ft, ¼″, 2000 psi) is a low-pressure, externally-heated hose assembly designed for use with Reactor 1/2 proportioners, featuring a ¼″ inside diameter, 25 ft length, and a thermocouple or ground-wire variant with scuff jacket for isocyanate or resin lines.
The Graco 249587 Reactor Heated Hose (25 ft, ¼″, 2000 psi) is engineered for premium
spray-foam and polyurea applications using Reactor 1 & 2 proportioner systems. With a 25-foot length and ¼-inch inside diameter, this
low-pressure hose assembly is rated to 2000 psi (≈138 bar), designed to maintain consistent fluid temperature through its external heating system and thermocouple feedback loop. The new multi-strand copper heating element delivers up to ten times the flex life of previous flat-copper designs, ensuring long-term durability and uniform heating without hot spots. Different fittings for isocyanate and resin lines help prevent mis-connection, while available scuff guard options (mesh or Xtreme-Wrap) protect the hose in rugged jobsite conditions. Proudly compatible with existing
Reactor heated hose systems, the 249587 model delivers reliable temperature control and serviceability for demanding spray‐foam or polyurea contractors.
