The Graco 55311 Asm Tip, Zip, 311 is a reversible airless spray tip assembly engineered for controlled paint application on narrow surfaces and detailed finishing work. Its 311 tip size delivers an approximately 6-inch spray fan with a 0.011-inch orifice, making it well suited for stains, sealers, lacquers, enamels, and other light to medium-viscosity coatings. The reversible ZIP design allows clogs to be cleared quickly by rotating the tip, helping minimize downtime during spraying.

Typical Applications
The 311 tip size is commonly selected when precision is more important than maximum coverage. It performs well on trim, moldings, cabinetry, furniture, doors, railings, and other smaller surfaces where accurate spray control helps reduce overspray while maintaining an even finish. It is recommended for thinner coating materials that flow efficiently through a 0.011-inch orifice.
