3M™ PPS™ Series 2.0 Lids are designed for the next generation 3M™ PPS™ Series 2.0 Spray Cup System. A ¼-turn locking system replaces a separate collar, letting you attach the lid to the hard cup with a quick twist. A domed design allows up to 90 ml (3 oz) of fluid below the filter, reducing inconsistent spray and sputter. Full-diameter filters and a wider fluid spout improve flow and filtration.
