Paint spray tip 521 is a spray nozzle designed for working with wall paints, facade paints, and primers, where fast coverage of large surfaces is important. The 521 designation means a spray angle of approximately 50° and an orifice size of 0.021” (approx. 0.53 mm), which translates into a wide working fan of about 25–30 cm at a standard distance from the surface. This size allows for smooth operation without constantly going back over the same areas or dealing with uneven coverage.
