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