3M™ PPS™ Series 2.0 adapter provides four points of connection from lid to gun and converts typical spray guns into ones that work with the 3M™ PPS™ Series 2.0 spray cup system. Specifically designed adapters allow painters to use PPS™ with virtually any spray gun model. To use this adapter, remove the existing spray gun cup. Then simply thread the correct PPS™ adapter into the spray gun.
