Optimum cartridge systems, 12 fl oz (360 ml)

Optimum® cartridges are molded from a proprietary polypropylene formulation and offer exceptional transparency, chemical compatibility, impact resistance and dimensional stability.
The Zero Draft™ design features a uniform inner diameter along the entire cartridge length with no stem-reducing or result-impairing plug movement, allowing for improved material flow characteristics and reduced turbulence. Unique reinforcing ribs at the outlet prevent cracking when installing fittings or nozzles. The 1/4" NPT outlet has a precision-molded thread and tapered counterbore for a tight, leak-proof seal.
The hexagonal outlet fits into the corresponding opening of the cartridge container, allowing fittings and nozzles to be installed quickly without the use of tools.



Optimum cartridges are available in transparent, green, amber with UV blocker and opaque black. Possible filling quantities are 2.5 oz (75 ml), 6 oz (180 ml), 12 oz (360 ml), 20 oz (600 ml) and 32 oz (960 ml).
