Heated B-side fluid hose designed to maintain consistent temperature and material viscosity in Graco Reactor systems for stable high-pressure spray performance.
The Graco 24M671 Reactor Heated Hose, B, 50', 3/8" is a high-performance heated fluid transfer hose designed for use in Graco Reactor proportioning systems. It maintains precise temperature control of the B-side material, ensuring proper chemical reaction, consistent viscosity, and stable spray performance in demanding polyurethane and polyurea applications.
Built for industrial spray environments, this 50-foot heated hose delivers reliable thermal regulation and fluid delivery under high-pressure conditions. It supports continuous operation in insulation, roofing, and protective coating systems where material temperature consistency is critical for application quality.
In plural-component spray systems, temperature stability directly affects chemical reaction quality and final coating performance. This heated hose helps maintain optimal material conditions from proportioner to spray gun, improving efficiency, adhesion, and overall system reliability.
