The DuraMORe wheel is a cushion rubber tread molecularly bonded to a new HardCore technology glass-filled nylon core. Hardcore tech cores will not rust, oxidize, or decay as cast-iron does. It resists chemicals, solvents, salts, grease, alkalines, and steam cleaning. HardCore wheels are replacing steel core wheels. Due to the nature of the compound's flex memory, test results show HardCore technology wheels absorb much more shock impact and abuse.
Temp range: -40°F to +160°F
No rust or wheel core decay
