| Optimum cartridges are molded from a proprietary FDA- and RoHS-compliant polymer that provides exceptional clarity, chemical compatibility and dimensional stability.
The new design features Zero DraftTM internal walls, improved fluid flow characteristics and reduced turbulence. External ribs at the outlet end prevent splitting when installing fittings or nozzles.
The ¼” NPT outlet has precision molded threads and a tapered counterbore for a secure, leakproof seal. A molded hex around the outlet fits into a matching orifice on the cartridge retainer to permit fast, tool-free installation of fittings and nozzles.
Optimum cartridges are available in clear, UV-blocking amber, and light-blocking black configurations. Capacities include 2.5 oz (74ml), 6 oz (177ml), 12 oz (355ml), and 20 oz (591ml).
Note: Optimum cartridges are backward-compatible with most retainers on the market today. |
