| Graco XP Plural-Component Sprayers | Retrofit for heated hopper circulation systems |
| Graco XP-hf Systems | Heat circulation through dual 20-gallon (75 L) hoppers |
The Graco 26C078 Kit, Retrofit, Hopper Heat Circ is a genuine retrofit package designed to add heated fluid circulation capability to compatible Graco XP and XP-hf plural-component systems. The kit provides the fittings, tubing, and connection components required to circulate heated fluid through dual 20-gallon hoppers, helping maintain material temperature during spraying operations.
By circulating heat through the hopper system, the kit helps keep temperature-sensitive coatings at a consistent viscosity, improving material flow and application performance in demanding industrial environments.
Maintaining coating temperature is critical when spraying high-viscosity epoxies, polyurethanes, and protective coatings. Continuous hopper heat circulation reduces temperature fluctuations, supports more consistent mixing, and helps improve overall spray performance.
This retrofit kit is commonly used in protective coating, marine, infrastructure, industrial maintenance, and other plural-component spray applications where material temperature control is essential for proper application and performance.
