3M™ Performance Gravity HVLP Atomizing Heads Variety Refill Kit includes nozzles in six sizes ranging from 1.2 to 2.0. Replaceable nozzles are built exclusively for gravity feed applications with the 3M™ Performance Spray Gun System and 3M™ PPS™ Series 2.0 Spray Cup System. Designed to deliver premium spray performance for coatings, including paints, clear coats and topcoats.What makes the 3M Performance Spray Gun system different is the technology inside the quick-change replaceable nozzles. Because paint and coatings never pass through the body of the spray gun, and only the atomizing head, it's like getting a brand-new spray gun every time you swap the nozzle. Get the pattern control, atomization and transfer efficiency you expect from a premium spray gun, all while helping to drive more consistent spray performance across each job, every day.
