ELIMINATING CRACKED ACRYLIC RESERVOIRS
Optimus uses only cast acrylic tubes from premium name-brand suppliers like Plexiglas® by Arkema and Polycast™ by Spartech. Cast acrylic tubing is one of the most difficult types of acrylic to make, but the quality is second to none.
The benefits of cast aren't small: extremely fracture resistant, highly stain resistant and excellent optical clarity.In fact, our cast acrylic is much stronger than acetal and nearly impossible to break. Feel free to allen wrench your fittings in place, our block won't blink.
CAST VS EXTRUDED ACRYLIC TUBE
Unlike cast, extruded acrylic tubing can be extremely cheap to purchase and it's easy to manufacture. That’s why extruded is used by nearly every watercooling company.But extruded acrylic isn't suited for liquid cooling parts. Extruded is prone to stress and spider web fractures from machining and expanding/contracting during temp fluctuations.
CAST VS INJECTION MOLDED NYLON TUBE
Like extruded acrylic, injection molded nylon feature similar downsides, including a +/- 10% expansion variation and high fluid retention, all sources of stress. Injection molding requires self-tapping screws, rather than CNCed threads, meaning the accuracy and service life of nylon is very low.
CAST VS BOROSILICATE GLASS TUBE
Borosilicate glass, while it looks great, has its own challenges. Glass can't be machined, thus requiring additional support to create the seal, opening a new host of potential leak issues. While borosilicate glass is much cheaper than cast acrylic, cast offers incredible durability and reliability while matching the clarity of glass.
