The Graco Gusmer GX-7 400 Spray Gun (295540) is a professional-grade, mechanical-purge plural-component spray gun designed for fast-setting polyurea and polyurethane applications. Its shortened stroke reduces the time material remains inside the gun, while impingement mixing, adjustable pattern control, and a self-cleaning purge mechanism support consistent spraying and easier maintenance. Rated for up to 3,500 PSI with an output range of 3.5–8 lb/min, the GX-7 400 is ideal for protective coatings, waterproofing, and compatible spray foam applications.
