Optimum® Cartridge Pistons


Optimum® cartridge pistons are precision molded from high-density polyethylene for a consistent fit that perfectly matches Nordson EFD cartridge walls for smooth travel and consistent results in fluid packaging and fluid dispensing processes.

Unique channels help dissipate air during the filling process, reducing or eliminating the need to centrifuge. Dual wiping edges eliminate fluid waste.

Capacities include 2.5 oz (75ml), 6 oz (180ml), 12 oz (360ml), 20 oz (600ml) and 32 oz (960ml).

Note: Optimum cartridges are backward-compatible with most retainers on the market today.

Follow these guidelines for safe operation.
