3M performance gravity HVLP atomizing heads variety refill kit includes nozzles in six sizes ranging from 1.2 to 2 mm. 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. 3M performance gravity HVLP atomizing head variety refill kit includes one of each size: 1.2 mm, 1.3 mm, 1.4 mm, 1.6 mm, 1.8 mm and 2 mm. Used for spraying a wide range of industrial and automotive coatings, including high viscosity coatings, sprayable fillers, high build primers, primer surfacers, sealers, single stage top coats, solvent based paints, waterborne paints and clear coats. The replaceable nozzles are used exclusively with the gravity fed 3M PPS series 2.0 spray cup system, which helps to reduce material waste, mess and contamination compared to traditional metal paint cups. Forget about tearing down spray guns and soaking in solvent. Our complete, integrated spray system is your path to smarter cleanup. The atomizing heads attach to the 3M performance spray gun needle and are tightly secured to the spray gun with a specially designed locking collar. No additional tools required for changeouts. Simply remove the nozzle from the spray gun and either appropriately clean the fluid tip or replace it to keep your spray gun performing like new.
