Apollo Standard "D" Cap for 7500 & 7700 Series Spray Guns

Apollo Standard  Cap for the Apollo 7500 & 7700 Series Spray Guns

The Apollo StandardCap for the Apollo 7500 Series Spray Guns and Apollo 7700 Series Spray Guns is a fluid/air cap designed for the highest material flow in the standard cap lineup.

Here's a clear breakdown of what it is and what it does:

What it is

• A  size standard air cap (not high-solids unless specified as HS)
• Used on Apollo HVLP turbine spray guns in the 7500 and 7700 series
• Typically paired with a 2.5 mm needle/nozzle set

What it's used for

The  cap is the heaviest-output standard cap, meaning it's built for thicker coatings and high-flow spraying, such as:

• Thinned latex paints
• Heavy primers
• High-viscosity enamels
• Some solvent-based adhesives or coatings

Key performance characteristics

• Largest fluid delivery in the standard cap lineup
• Designed to atomize thicker materials without excessive thinning
• Produces a wide, wet spray pattern
• Optimized for fast coverage on large surfaces

Compatibility note

• Standardcap ≠ High Solids (HS)cap (HS version is for even thicker materials)
• Works across both 7500 and 7700 Apollo turbine guns as long as needle/nozzle match

If the smaller caps are for fine finishes, the cap is the "heavy hitter"; it's what you use when you want to push more material quickly, and you're spraying something too thick for the smaller caps to handle efficiently.
