Dependability meets performance in the GX-7 and GX-8 spray-foam guns. Graco has cemented its reputation as the leading manufacturer of high-quality spray-foam guns. At SPF Depot, we carry an extensive selection of Graco replacement parts, including parts for the GX-7 and GX-8 models. Take a look at our full inventory of factory OEM and aftermarket parts for repairing your spray-foam gun.
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
