The Graco GX-7A spray foam gun and GX-7A 400 remain trusted tools for professional spray foam contractors who need consistent performance and durability in roofing and concrete jacking. Keeping your equipment running efficiently requires access to high-quality replacement parts, including seals, filters, and internal handle components.

At SPF Depot, we stock a full range of GX-7A and GX-7A 400 parts designed to support routine maintenance and full rebuilds. This includes parts to prevent material crossover, O-ring kits to maintain pressure integrity, filter screws and screens to protect internal passages, and check valves to ensure proper chemical separation. Whether you are troubleshooting a spray issue or performing scheduled maintenance, having the right parts on hand helps reduce downtime and improve spray consistency.

Many GX-7A performance issues can be traced back to normal wear items. Worn valve rods and modules that may lead to crossover, clogged filter screws can restrict flow, and aging O-rings can cause pressure loss or leaks. Replacing these components regularly is one of the most effective ways to extend the life of your spray gun and maintain optimal performance in the field.

SPF Depot offers both OEM and high-quality aftermarket GX-7A parts, giving contractors the flexibility to choose cost-effective solutions without sacrificing reliability. Our SPF Depot brand components are engineered for durability and are often available at significant savings compared to OEM pricing. With a large inventory in stock, most GX-7A parts are available for same-day shipping so you can get back up and running quickly.
