About GX-7 and GX-8 Spray Guns

While both Graco models offer unbeatable spray-foam gun technology, the GX-7 and GX-8 have unique features, making them ideal for different situations. One of the biggest differences is that the GX-8 model is for low-output applications and aims to reduce overspray, leading to a more contained consumption of materials. The GX-7 comes in three different models to better fit your specific job needs.

Graco GX-7 Spray-Foam Gun Features

  • Performs in challenging conditions
  • Best for applying two-component foam systems
  • Superior pattern control
  • Ideal for working with polyurethane foam and elastomeric coatings
  • Applications: Residential (roofing, concrete and insulation), tank and pipe coatings, water and waste-water treatment
  • Internal impingement design leads to optimal mixing and pattern control
  • Increased spray time due to adjustable air-cap cleaning
  • A and B filters are easy to clean for less downtime between applications
  • Mechanically self-cleaning so no need for expensive or harmful solvent-flushing
  • Interchangeable pattern control disc allows for round or fan spray and different pour patterns

Graco GX-8 Spray-Foam Gun Features

  • Designed for low-output, fast-set polyurea, polyurethane and hybrid coatings application
  • Direct impingement mixing leads to high yield and a superior surface finish
  • Gun's tip stays cleaner longer due to an optimized air-volume-to-air-cap ratio
  • Solvent-free, mechanically self-cleaning
  • Enjoy optimized material consumption by reducing overspray associated with low-output spraying
