It is an elastomeric polymer that is NSF/ANSI 61 certified, the toughest standard governing products coming into contact with potable water. It also meets the BS 6920 standard. Chlorazone was designed to prevent premature product degradation by resisting harmful environmental elements, including:

  • Chloramines
  • Household cleaning chemicals
  • Acids and bases
  • Sunlight and ultraviolet radiation
  • Ozone
