Apollo Blue High-Solids "C" Cap for 7500 & 7700 Series Spray Guns

Apollo Gold High-Solids “B” Cap for the Apollo 7500 & 7700 Series Spray Guns

The Apollo Blue High-Solids “C” Cap is an air cap (atomizing cap) designed for use on Apollo Sprayers 7500 and 7700 series HVLP spray guns, specifically for spraying high-viscosity / high-solids coatings.

Here’s what it is and how it fits in:

• It’s the “C” size high-solids air cap (HS version)
• Designed for larger fluid delivery and heavier materials like:
  • latex paints
  • primers
  • thick industrial coatings
• Typically paired with:
  • 1.8 mm and 2.0 mm needle/nozzle sets
• Part of Apollo’s High Solids (HS) system, which improves atomization of thick coatings in turbine HVLP setups

Key purpose

This cap changes how the spray gun atomizes paint:

• More air + fluid handling than standard caps
• Better breakup of thick coatings so they spray smoother
• Helps avoid “spitting” or poor atomization with heavy materials

Important compatibility note

• Works only with Apollo 7500 / 7700 series guns
• It’s part of a matched system (cap + needle + nozzle must be compatible for best results)

If you're spraying heavy-bodied coatings (latex, primers, thick finishes) on a 7500/7700 gun, the Blue HS “C” cap is the correct high-output atomizing cap for that job.
