Chemfluoro Convoflex WCSR Multipurpose Chemical Transfer Hose is designed for bulk-chemical transfers where corrosive chemicals, such as acids, may damage the stainless-steel braid commonly used as a cover on transfer hoses. The new hose is said to provide longer service life while enhancing plant and worker safety. The new hose’s highly engineered, low-profile helical convoluted inner-core design provides superior flexibility without kinking. This hose is constructed of a chemically resistant, high-purity Chemfluor PTFE inner core and is reinforced with 304 high-tensile strength stainless-steel braids and an acid-resistant EPDM (ethylene diene monomer) outer cover. — Saint-Gobain Performance Plastics, Akron, Ohio
