The corrosion-resistant coating has passed the standard corrosion test required by the approving agencies indicated in the Approval Chart. These
tests cannot and do not represent all possible corrosive environments. Prior to installation, verify through the end-user that the coating is compatible
with or suitable for the proposed environment. For automatic spray nozzles, the coating is applied to the exposed exterior surfaces only. Note that
the spring is exposed on sprinklers with PTFE coatings. For PTFE coated open spray nozzles only, the waterway is coated.
