Optimum cartridges are made of a new polymer that provides exceptional clarity, chemical compatibility, impact strength and dimensional stability. The proprietary Zero Draft™ design ensures that the internal diameter is consistent from top to bottom, with no taper to restrict piston travel and affect process results.
Optimum pistons are molded so they mate perfectly with cartridge walls. Their consistent dimensions and fit prevent blow-by and leakage during filling and storage, and precision wiper edges eliminate waste as fluid is dispensed to reduce production costs.
New, see-through cartridge retainers (an industry first) permit easy visual confirmation of fluid levels. Retainer caps feature a large ergonomic gripping surface, a convenient push-in air line connector and locking tabs that snap into place with an audible click to confirm proper installation.
Optimum cartridges are available in 2.5 oz (75 ml), 6 oz (180 ml), 12 oz (360 ml), 20 oz (600 ml) and 32 oz (960 ml) capacities. All EFD Optimum dispensing components are produced silicone-free by Nordson EFD in the USA and are certified safe for industrial use.
