What's the best spray foam gun?

We get asked this very question on a daily basis. What is the top spray foam gun? There's a lot of factors that play into the answer of that question along with personal preference. The Graco Fusion AP has been among the most popular and user friendly guns in the industry for the past 15 years. While the AP gun has been relied on for years, there's always room for improvement right? The release of the new Fusion ProConnect gun aim's at just that.

This new gun keeps all of the great features of the AP gun like it's great performance, pattern, and ergonomics while GREATLY reducing the amount of parts and labor required to perform a rebuild. Imagine a complete fluid section, factory quality, rebuild in minutes. The old days of soaking parts and the effort of scrubbing each part until spotless are gone. The new PC gun features a replacement cartridge head that replaces multiple individual parts with a single component.

With ProConnect technology in the Fusion PC gun (right), the entire fluid section including the side seals and all associated o-rings are replaced in a single cartridge compared to individual parts like the Fusion AP (left). This allows you to rebuild you gun like a pro and finish your job every time.


  • Crossover containment
    • The ProConnect replacement cartridge includes A & B check valves as well as an air-purge check valve to keep any crossovers contained inside the cartridge.
  • Factory quality rebuild
    • The replacement cartridge comes fully assembled and factory tested to ensure a factory quality rebuild each time reducing labor cost.
  • Ergonomic
    • Keeping the Fusion AP design guarantees that comfortable Fusion AP feel making it easy to spray all day long
  • Chrome-X coated mix chamber
    • The all new PC designed mix chamber is coated with Graco's tested Chrome-X coating with near diamond like hardness with 10 times the wear resistance over a standard chamber.
