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 Refill Kit includes five 1.4 size nozzles, ideal for clearcoat, solvent base color, single stage top coat, direct gloss, primer sealer, wet on wet primer, primer surfacer, high build primer. Nozzle recommendations are starting points only; refer to paint manufacturer for recommendations on fluid tip size. 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.
