Square-Profile Chemical-Resistant Viton® Fluoroelastomer Cord Stock

The flat edges of this cord stock contact more surface area than round-profile cord stock, forming a tighter seal in faucets and other stationary parts. It’s also less likely to twist or shift in equipment with repeated pressure changes, such as molding machines. Made of Viton® fluoroelastomer, this cord stock resists a wide range of chemicals, including benzene, boric acid, and ethylene glycol.
